Cells were seeded in tissue culture dishes as described above. For labelling, the cells were starved using IM medium (Glasgow minimal essential medium buffered with 10 mM Hepes, pH 7.4). After 1 h, the medium was replaced by IM with 3H-palmitate at 200 µCi/mL (American Radiolabeled Chemicals, US) for 2 h at 37 °C. Cell lysis, immunoprecipitation and SDS-PAGE were performed as above. The gels were fixed for 30 min with 10% acetic acid, 25% isopropanol in water and the signal was amplified for 30 min with NAMP100 (GE Healthcare, US). The gels were then dried and applied to an Amersham Hyperfilm MP (GE Healthcare, US). The radioactivity was visualized and quantify using a Typhoon TRIO (GE Healthcare, US).

Comprehensive Western Blot Analysis Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
Western blotting was carried out as described previously [11 (link), 12 (link)]. Whole cell extracts (50 µg/lane) were dissolved on 7.5% acrylamide gels and transferred onto Polyvinyl difluoride (PVDF) membranes (Immobilon-P, 0.45 µm, Merck Millipore). Primary antibodies (Table 1) were diluted 1:1000 (except anti-ARNT 1:2000) and applied overnight. Determination of Lamin A/C was done for normalisation and the appropriate antibody was applied for 1 h at room temperature. Afterwards PVDF membranes were incubated with HRP-conjugated secondary antibodies (1:5000, DAKO) for 1 h at room temperature. Chemoluminescence development was achieved using the ECL reagent (Clarity™ Western ECL, Bio-Rad). Subsequently membranes were exposed to X-ray films (Amersham Hyperfilm MP, GE Healthcare) and signals were quantified using the AIDA Image Analyzer (Version 4.27, Raytest).

Quantifying Serotonin Transporter Binding

Check if the same lab product or an alternative is used in the 5 most similar protocols
Serotonin transporter (SERT) binding was determined on brain sections, cut as above, using (3H)-paroxetine (Perkin Elmer, UK) as previously described [61 (link)]. Slides were then exposed to (3H)-sensitive film (Amersham Hyperfilm MP, GE Healthcare, UK) at −80°C for 6 weeks. Analysis of autoradiographs was performed by measuring the signal over the area of interest with densitometry software (MCID Basic 7.0, Imaging Research, Inc.). The background was subtracted.

Ethidium bromide-stained gels and western blots were imaged with a BioRad ChemiDoc XRS + system.
Gels containing radioactive samples were dried onto chromatography paper (GE Healthcare, 3030-861) and imaged with a Typhoon FLA 7000 phosphorimager (GE Healthcare) for quantitative analyses. Dried gels were also exposed to Amersham Hyperfilm MP (GE Healthcare, 28906843) and scanned for data presentation.

Protein expression on immunoblots was quantified on 8-bit gray-scale-transformed.tiff images of either scanned Amersham Hyperfilm MP (GE Healthcare, 28906838) or.tiff images obtained by the Bio-Rad ChemiDoc imaging system. Fiji ImageJ was used to select a region of interest for the respective proteins for densitometric analysis. Protein expression for each protein was normalized to the loading control of the respective sample.

Northern Blot Assay for RNA Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Northern blot experiments were essentially performed as described (Vasiljeva & Buratowski, 2006 (link)). RNA was prepared as described in Kilchert et al (2015) (link). 8 μg of RNA were resolved on a 1.2% agarose gel containing 6.7% formaldehyde in MOPS buffer. After capillary transfer in 10× SSC onto a Hybond N+ membrane (GE Healthcare), RNA was UV-crosslinked and stained with methylene blue to visualise ribosomal RNAs. Gene-specific probes were generated by random priming in the presence of ATP [α32P] using the Prime-It II Random Primer Labeling Kit (300385; Agilent) using PCR-generated DNA templates produced from genomic DNA isolated from a wild type S. pombe strain (YP71) with the oligonucleotides listed in Table S11. Probes were added to the membrane and hybridised at 42°C overnight. After repeated washes in 2× SSC, 0.1% SDS, blots were exposed to Amersham Hyperfilm MP (28-9068-44; GE Healthcare).

After separation by electrophoresis using a 15% polyacrylamide gel, proteins was blotted to a 0.45 µm nitrocellulose membrane (GE Healthcare, Uppsala, Sweden). Blotting was performed at 150 mA for 45 min. at 4 °C. Patients sera were diluted in TBS-T containing 1% BSA and 100 µg HRP as for ELISA. The secondary antibody, HRP conjugated goat anti-human IgE (KPL, Gaithersburg, MD, USA) was diluted 1:10000 in TBS-T + 1% BSA and incubated for 2 h at room temperature on the membrane. Blots were developed using the Clarity ECL Western Blot Substrate (Bio-Rad Laboratories, Inc.) following the manufacturers instruction. The membrane was placed in a light protected cassette (Hypercassette, Amersham, GE Healthcare, Japan) and exposed to an X-ray film (Amersham Hyperfilm™ MP; GE Healthcare, Japan) in the dark. Depending on the signal, films were exposed between 0.5 and 10 min and developed using a CP1000 AGFA film processor (Superior Radiographics, LTD., Madison, WI, USA).

Western blot analysis was performed on total crude protein lysates from cultured hiPSC-CMs in the different conditions. Same amount of proteins (20 μg/lane) of single samples or pooled samples (n = 5–6) were separated on a 10% SDS-polyacrylamide (29:1) mini-gels (Bio-Rad) and transferred by wet-electroblotting to nitrocellulose membranes. Membranes were stained with the primary antibodies directed against the M-motif of cMyBP-C (polyclonal, 1:10,000, custom made) and α-actinin (monoclonal, 1:10,000, Sigma). Peroxidase-conjugated secondary antibodies against mouse (1:20,000, Dianova) or against rabbit (1:20,000, Sigma) were used. Proteins were visualized using Amersham ECL Prime Western Blotting Detection Reagent (GE Healthcare), and the signals were detected on Amersham Hyperfilm MP (GE Healthcare).

Check if the same lab product or an alternative is used in the 5 most similar protocols
RNA extraction, gel electrophoresis, blotting, and detection with a radiolabeled probe were performed as described previously (29 (link)) but with the following adjustments. Ten micrograms of total RNA for each cell line was loaded onto the gel. The probes were labeled with the DecaLabel DNA labeling kit (Thermo Fisher Scientific), and the membrane was exposed to Amersham Hyperfilm MP (GE Healthcare) for 8 days (in the case of the SERINC5-specific probe) or for 8 h (glyceraldehyde-3-phosphate dehydrogenase [GAPDH]-specific probe) at −80°C. The SERINC5-specific probe of 870 bp was prepared by digestion of a plasmid bearing the SERINC5 cDNA with XbaI and NotI. For the loading control, a GAPDH plasmid (a gift from K. Habers, Heinrich-Pette-Institut, Hamburg, Germany) was digested by EcoRI, generating a 1.3-kbp GAPDH-specific probe.

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.
