Surface-Active Agents

Surface-Active Agents, also known as surfactants, are compounds that lower the surface tension of a liquid, allowing easier spreading and penetration.
They are widely used in a variety of industrial and consumer applications, including detergents, emulsifiers, wetting agents, and dispersants.
Surface-Active Agents can be derived from natural sources, such as plant oils or animal fats, or synthetically produced.
These versatile compounds play a crucial role in enhancing the effectiveness and efficiency of many products and processes.

Improving Single-Cell RNA-Seq Sensitivity
Cited 86 times
In single-cell RNA-Seq, small amounts of sample loss during a number of steps can lead to significant decreases in transcript detection sensitivity. A decrease in assay sensitivity results in data that is only accurate and reproducible for highly expressed genes, limiting the scope and confidence of gene expression analyses. Further complications in assay sensitivity arise from an uneven distribution of sequencing reads along a transcript; usually, in SMARTer, there is a bias towards more reads at the 3′ end of the transcript. Even coverage along a transcript improves the accuracy of analytical tools used to quantify gene expression and transcript isoform abundance. A method published by Picelli et al (Nature Methods, 2013) modified the traditional SMARTer protocol to address this by improving transcript detection, coverage, accuracy, yield, and cost. Following the same strategy as SMARTer library construction, Smart-seq2 uses several alternative reagents to generate whole-transcriptome full-length cDNA libraries.
Avoiding small-volume, bead-based SPRI cleanups of each sample is an effective way of reducing loss and increasing assay sensitivity. Lysing single cells in a guanidine thiocyanate buffer necessitates SPRI cleanup due to the protein denaturing effects of the compound, which will affect downstream reactions, like reverse transcription. Multiple alternative lysis buffers exist that address this. The Ambion Single Cell Lysis buffer (Life technologies, #4458235), often used for single-cell RT-PCR, only requires the addition of a stop solution to inactivate its lytic activity before subsequent reactions. A hypotonic lysis buffer with small amounts of RNase-inhibitor and surfactant, as described in Smart-seq2, is the preferred buffer due to the lack of a need for a post-lysis cleanup or the addition of a stop solution prior to reverse transcription. However, the optimal lysis strategy will depend on the experimental system being analyzed.
Smart-seq2 takes additional steps to minimize sample loss during library construction. The reverse transcription is improved by the addition of betaine and additional magnesium chloride to the reaction mix and by the use of a template-switch oligonucleotide with one locked nucleic acid (LNA) riboguanosine base. These improvements assist in the hybridization between the template-switch oligonucleotide and the cDNA product, thereby increasing the probability of successfully introducing a second PCR adapter onto the cDNA product (see Figure 1). A second key improvement was made in the preamplification PCR step, which can be heavily biased against either long transcripts or those containing regions with high G/C content. Picelli et al found that the preamplification PCR is improved by using the KAPA HiFi HotStart ReadyMix, which dramatically improved coverage and sensitivity, particularly for GC-rich transcripts.

Arabidopsis Transformation via Floral Dip
Cited 39 times
- Grow healthy Arabidopsis plants until they are flowering (see Figure 1A).
Optional: Clip first bolts to encourage proliferation of many secondary bolts. Plants will be ready roughly 4–6 days after clipping. Optimal plants have many immature flower clusters and only few fertilized siliques, although a range of plant stages can be successfully transformed.
- Transform the DNA construct of interest into the appropriate Agrobacterium strain. Grow the transformed Agrobacterium on YEB (or LB) plates containing the appropriate antibiotics in a 28°C incubator.
- Select a colony and resuspend bacteria in 10 μl H2O. Plate half of the volume immediately as a lawn onto a YEB plate with the suitable antibiotics and incubate at 28°C for (2–3 days), and use the other half to verify the presence of your DNA construct by PCR analysis.
- Collect the densely grown bacteria from the plate by scraping, and resuspend them in 30 ml YEB in a sterile Falcon tube. The OD600 should be about 2.0.
- Per transformation prepare 120 ml of 5% sucrose solution containing 0.03% of Silwet L-77 (surfactant; Lehle Seeds), pour solution into a disposable plastic bag and add the bacteria.
- Dip the inflorescences of the plants into the Agrobacterium solution for 10 seconds, under gentle agitation. You should observe a film of liquid coating the plants. The bacteria are distributed to all plant parts including very young flower shoots by gently pressing the outside of the bag with your hands.
- Place dipped plants under a lid or cover for 16 to 24 hours to maintain high humidity (plants can be laid on their sides if necessary). Do not expose to excessive sunlight (the temperature under the lid can get high).
- Water and grow the plants as normal, tying up loose bolts with wax paper, tape, stakes, twist-ties, or by other means. Stop watering as seeds become mature.
- Harvest dry seeds.
- Select for transformants using appropriate antibiotics or herbicides.

Three identical transcriptional cassettes for luxI, aiiA, and yemGFP were constructed by replacing a modular pZ plasmid’s promoter 47 (link) (with yemGFP) with the lux operon from the native Vibrio Fischeri operon (luxR up to luxI stop codon) 48 (link). LuxI and aiiA49 genes were cloned in place of yemGFP and a degradation tag was added to the carboxy-terminal of each. A previously used MG1655 strain of Escherichia coli1 was transformed with plasmids pTD103luxI/GFP(colE1,Kan) and pTD103aiiA(p15A,Amp) to create strain TDQS1 (Suppl. Info).
Each experiment started with a 1:1000 dilution of overnight culture grown in 50mL LB (10g/L NaCl) with antibiotics 100µg/ml ampicillin(Amp) and 50µg/ml kanamycin(Kan) for approximately 2 hours. Cells reached an OD600 of 0.05–0.1 and were spun down and concentrated in 5mL of fresh media with surfactant concentration of 0.075 Tween20 [Sigma-Aldrich, St.Louis,MO] before loading in a device.

DNA samples were purchased from Sigma-Aldrich as desalted ss oligomers at 100 μM concentration in water. SPR measurements were recorded at 20°C with a Biacore T200 system (GE Healthcare). All experiments described herein were performed using ReDCaT with a single Sensor Chip SA (GE Healthcare), which has four flow cells each containing SA pre-immobilized to a carboxymethylated dextran matrix. Two types of protocol were followed (detailed in Supplementary Methods): ‘affinity’ protocols were used to determine the dissociation constants for specific protein–DNA interactions, and ‘screening’ protocols were used for all other types of experiment. For the screening experiments, flow cells 1 and 2 were used as the reference (FCref) and test flow cells (FCtest), respectively. For the affinity experiments, flow cells 3 and 4 were used as FCref and FCtest, respectively. Throughout the SPR procedures, all samples were prepared, and all experiments were performed, in HBS-EP+ buffer [150 mM NaCl, 3 mM EDTA, 0.05% (v/v) surfactant P20, 10 mM HEPES (pH 7.4); GE Healthcare]. A cartoon representation of the ReDCaT Chip methodology and a typical SPR sensorgram are shown in Figure 2.

EXAMPLE 1

In an AISI 316 steel vertical autoclave, equipped with baffles and a stirrer working at 570 rpm, 3.5 liter of demineralized water were introduced. The temperature was then brought to reaction temperature of 80° C. and the selected amount of 34% w/w aqueous solution of cyclic surfactant of formula (VI) as defined above, with Xa=NH4, was added. VDF and ethane were introduced to the selected pressure variation reported in Table 1. A gaseous mixture of TFE-VDF in the molar nominal ratio reported in Table 1 was subsequently added via a compressor until reaching a pressure of 20 bar. Then, the selected amount of a 3% by weight water solution of sodium persulfate (NaPS) as initiator was fed.

In particular, the polymer (F) of the present invention as notably represented by the polymers (F-1), (F-2), surprisingly exhibits a higher elongation at break at 200° C. as compared to the polymers (C-1) and (C-2) of the prior art.

Also, the polymer (F) of the present invention as notably represented by the polymers (F-1), (F-2), despite its lower tensile modulus, which remains nevertheless in a range perfectly acceptable for various fields of use, surprisingly exhibits a higher strain hardening rate by plastic deformation as compared to the polymers (C-1) and (C-2) of the prior art.

Finally, the polymer (F) of the present invention as notably represented by the polymers (F-1) and (F-2) surprisingly exhibits higher environmental stress resistance when immersed in fuels as compared to the polymers (C-1) and (C-2) of the prior art.

Yet, comparison of polymer (F) according to the present invention with performances of polymer (C-3) comprising perfluoromethylvinylether (FMVE) as modifying monomer shows the criticality of selecting perfluoropropylvinylether: indeed, FMVE is shown producing at similar monomer amounts, copolymer possessing too high stiffness, and hence low elongation at break, unsuitable for being used e.g. in O&G applications.

Example 2

Thuricide BT Caterpillar Control (Southern Ag) was used as the source of viable Bacillus thuringiensis spores (6 million spores/mg). A dilution series was produced from Thuricide BT to show that the material is viable and could be readily cultured on Petrifilm plates. Three DEE chemical compositions were evaluated: (1) about 0.06 M copper (II) chloride in water, (2) about 1 wt.-% surfactant and about 10 wt.-% PCSR in water, and (3) about 1 wt.-% surfactant and about 1 wt.-% PCSR in water. OxiClean was used as the PCSR and Tween 80 as the surfactant. During testing of each DEE composition, the DEE composition was added to the spores to yield a 1:100 dilution of spores and exposed to 2.45 GHz microwave radiation for about 10 s. After exposure, the cells were centrifuged and washed to remove the DEE composition and then plated on Petrifilm and cultured for 24 h at 30° C. When using each of the three DEE compositions shown above, the decontamination method destroyed BT spores at 6-7 log kill levels and demonstrated the efficacy of bleach-free treatments.
