Sourdough Fermentation Kinetics

Check if the same lab product or an alternative is used in the 5 most similar protocols
Competition between GFP-labelled and unlabeled strains and single strain fermentations kinetics were performed in a sourdough synthetic medium (SSM) that was adapted from [64] to better mimic the average composition of sourdoughs. The SSM contained, per liter: wheat peptone, 24 g; MgSO 4 .7H 2 0, 0. (Accuri, BD Biosciences). For competition experiments, 5.10 5 cells/mL of each strain were then inoculated in 15 mL SSM medium. For single strain analysis of fermentation kinetics, 10 6 cells/mL of pre-culture were inoculated in 15 mL SSM media.
Fermentations were carried out at 24 °C with constant magnetic stirring (300 rpm) in 20 mL glass tubes closed with a filter tip to allow release of CO 2 . Fermentations were monitored during 24 h for CO 2 release, by measuring weight loss every 40 min using an automated robotic system [65] .
At the end of fermentation, cultures were centrifuged and pellets were resuspended in PBS for flow cytometry analysis (C6 cytometer, Accuri, BD Biosciences). Population size and cell viability were determined as described in [66] (link). Relative fitness of tetraploid vs diploid strains was estimated based on the proportion of GFP-labelled vs unlabelled strains in mixed cultures. GFP fluorescence (excitation 488 nm, emission 530 nm) was collected in the FL1 channel.

Check if the same lab product or an alternative is used in the 5 most similar protocols
To determine CCL2 binding levels for ACKR2-WT and ACKR2-V41A, cells were incubated with conjugated CCL2-AF647 (ALMAC, Cat# CAF-02-D-2) at 37 °C for 45 minutes at different concentrations ranging between 100 to 750 nM. After two washes receptor expression was analyzed on a BD Accuri. To determine the levels of ACKR2-WT and ACKR2-V41A receptor expression, cells were stained with anti-CD16/32 (Fc block) on ice for 20 minutes. After two washes, cells were stained for 30 minutes at 37 °C with anti-human ACKR2 polyclonal IgG antibodies, washed twice, and then stained for 30 minutes at 4 °C with anti-human IgG conjugated with PE. In the CCL2 competitive binding assay levels for ACKR2-WT and ACKR2-V41A, cells were incubated with unconjugated CCL2 (PEPROTECH, Cat #300-04100UG) at 37 °C for 45 minutes. After two washes and an Fc block as described above, cells were stained for 30 minutes at 37 °C with anti-human ACKR2 polyclonal IgG antibodies, washed twice, and then stained for 30 minutes at 4 °C with anti-human IgG conjugated with PE. After two washes, levels of binding of the ACKR2 antibody was analyzed in BD Accuri.

Binding of yeast-displayed hVISTA (Phe33-Ala194, Uniprot #Q9H7M9) to soluble SG7, BMS767, and VSTB112 antibodies (Supplementary Fig. S5A, S5B) was measured. Titrations of antibody were incubated with yeast in PBS/BSA (pH 6.0 or pH 7.4) at 4 °C for 12 h to allow interactions to reach equilibrium. Binding signal was measured on a BD Accuri and analyzed on FlowJo and GraphPad Prism as before. PBS/BSA at pH 6.0 was prepared by titrating in hydrochloric acid to standard PBS + 1 mg/mL BSA. hVISTA and mVISTA mutants were displayed on yeast for single clone analysis (Fig. 3c,e). Mutants based on wild-type hVISTA ECD (Phe33-Ala194, Uniprot #Q9H7M9) or wild-type mVISTA ECD (Phe33-Ala191, Uniprot # Q9D659) were induced for surface expression on yeast as described previously. Yeast-displayed clones were incubated with a concentration of each antibody at its estimated Kd value (SG7: 300 pM; BMS: 3 nM; or VSTB: 3 nM) in PBS/BSA at pH 7.4 (SG7, VSTB112) or pH 6.0 (BMS767) at 4 °C for 12 h to allow interactions to reach equilibrium. Binding signal was measured on a BD Accuri and analyzed on FlowJo and GraphPad Prism as before.

Cells suspended in PBS (5 × 106/mL, 100 μL) were incubated with the primary antibodies control IgG or anti-podoplanin Ab (NZ-1) at 5–10 μg/mL or the recombinant proteins (hFc2 or hCLEC-2-hFc2) at 100 ∞g/mL. After washing with PBS, these cells were resuspended with 100 ∞L of PBS and stained with 3 ∞L of secondary antibodies (anti-hamster IgG or anti-human IgG) conjugated with fluorescein isothiocyanate (FITC) for 15 min.
Where indicated, cells suspended in modified Tyrode’s buffer supplemented with vehicle, 1 mM CaCl2, or 1 mM EDTA were incubated with or without GST-tagged S100A13 recombinant protein at 20 ∞g/mL. Then the unbound recombinant proteins were washed with PBS and the binding of S100A13 protein to the cells was detected by 10 ∞g/mL anti-S100A13 antibody (63Y, Santa Cruz Biotechnology, Inc.) and anti-mouse IgG conjugated with Alexa Fluor 488.
Surface expression of endogenous S100A13 was also analyzed by flow cytometry. CASMCs pretreated with or without H2O2 as described above were incubated with 10 ∞g/mL control mouse IgG or anti-S100A13 antibody (63Y), followed by Alexa Fluor 488-conjugated anti-mouse IgG.
The stained cells were immediately analyzed using a FACScan or BD Accuri (BD Biosciences). The data were recorded and analyzed using CellQuest software or BD Accuri CFlow software.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
