Anti sox10 antibody

Manufactured by Santa Cruz Biotechnology
Sourced in United States

The Anti-SOX10 antibody is a laboratory tool used to detect the presence of the SOX10 protein in biological samples. SOX10 is a transcription factor that plays a crucial role in the development and function of various cell types, including neural crest cells and Schwann cells. This antibody can be used in techniques such as Western blotting, immunohistochemistry, and immunocytochemistry to identify and analyze the expression of SOX10 in research applications.

ChIP Assay for Transcription Factor Binding Analysis

ChIP assay was performed according to the protocol supplied with a premix kit (Merck, 17-295). B16-F0 cells were reacted with 1% formaldehyde for 10 min to cross-link between DNA and proteins. Cell extracts were sonicated to yield chromatin fragments with about 200-500 base pairs (bp) in size. Chromatin fragments were incubated with anti-CRTC1 (Cell Signaling, 2587), anti-β-catenin (Cell Signaling, 9562) or anti-SOX10 antibody (Santa Cruz, sc-17342) at 4℃ overnight, and precipitated with protein A-sepharose bead-sheared salmon sperm slurry for 4 h. To reverse the cross-links, ChIP elutes were incubated with 80 mM NaCl for 6 h at 65℃, and supplemented with 40 mM Tris-HCl containing 0.4 mg/ml proteinase K (Sigma-Aldrich, P2308) and 10 mM EDTA in another incubation for 1 h at 45℃. Input and precipitated DNAs were subjected to quantitative PCR encompassing CREB-, LEF1- or SOX10-responsive element at the MITF-M promoter in mice. Nucleotide sequences of PCR primers are described in Table S2. Quantitative PCR with SYBR green (Qiagen 204054) was subjected to 40 cycles in a condition of denaturation for 10 s at 95℃ and combined annealing-DNA extension for 30 s at 60℃.

ChIP Assay in Rat Schwann Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
We performed ChIP assays in primary rat Schwann cells with an EZ ChIP kit (Upstate) as described by the manufacturer. Briefly, we obtained DNA, crosslinked to protein with formaldehyde, and sheared the DNA by pulsed ultra-sonication. For immunoprecipitation, we used an anti-SOX10 antibody (Santa Cruz) or a rabbit IgG antibody (negative control). Primer sets, spanning the identified response element, ranged from −421 to −157 bp (site AB), from −421 to −224 bp (site A), from −285 to −46 bp (site B), and from −78 to +169 bp (site D) relative to the transcriptional start site.

ChIP-PCR of CREB and SOX10

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cells were incubated with 1% formaldehyde (Sigma-Aldrich, F8775) to cross-link between DNA and proteins, and sonicated to yield chromatin fragments with about 200-500 base pairs. Chromatin fragments were reacted with anti-CREB antibody (Cell Signaling, 9197) or anti-SOX10 antibody (Santa Cruz, sc-17342) at 4℃ overnight, and precipitated with protein A-sepharose bead-sheared salmon sperm slurry (Merck, 17-295) for 4 h. Input and precipitated DNAs were subjected to PCR encompassing CREB- or SOX10-responsive element at the MITF-M promoter. Nucleotide sequences of PCR primers are previously described 35 (link). PCR products were resolved on agarose gels by electrophoresis and stained with EcoDye.

ChIP assays were performed as described previously (20 (link)). Antibody used was anti-RNA polymerase II serine2 phosphorylation (Abcam, MA, USA) or anti-SOX10 antibody (Santa cruz). Primers used were; 5’- GAG GAA ACT GAG GTC CAA AGA A −3’ (sense) and 5’- GCC CAG ACT TCA GAG CTA ATC −3’ (antisense) for the PD-L1 intron 3 gene region, 5’- GCA AAG GCA TTC CAC TGT TC −3’ (sense) and 5’- GCA TCT TCT ACC TCC ATC CAT AC −3’ (antisense) for the PD-L1 exon 7 gene region, 5’- TGG AGG GAA TCG TGA CCT A −3’ (sense) and 5’- GCT AAG ACC AGG ACG CTA AC −3’ (antisense) for the IRF1 intron 1 gene region, 5’- AGG GCA GCT GAT CTC TTC A −3’ (sense) and 5’- GGC TAA ACC TGG CAC CAA A −3’ (antisense) for the IRF4 intron 4 gene region, and 5’- TGG GCT GTT TCT GGT AAT CA −3’ (sense) and 5’- CAC CTT GGA ATT TCC TGT GC −3’ (antisense) for the MIA gene region.

Whole-cell extracts (10 μg/lane) or nuclear extracts were prepared using the method of Schreiber, E. et al.(19 (link)) and then subjected to Western blotting analysis using anti-SOX10 antibody (Santa Cruz), anti-MITF antibody (C5), anti-IRF4 antibody (Santa Cruz), anti-IRF1 antibody (Cell Signaling Technology, Danvers, MA, USA), anti-α-tubulin antibody (Sigma), or anti-Histone H3 antibody (Abcam). The band intensities were measured by ImageJ and normalized to that of each control lane.

Immunohistochemistry was performed as described previously slight modifications57 (link),58 (link). Coronal sections were permeabilized with 0.3% Triton X-100/PBS and incubated overnight with primary antibodies in 2% bovine serum albumin (BSA)/PBS, then washed with 0.3% Triton X-100/PBS three times for 5 min each. The sections were incubated with secondary antibodies and Hoechst 33342 in 2% BSA/PBS for 2 h, and then washed with 0.3% Triton X-100/PBS three times for 5 min each. The sections were mounted on slides with Mowiol (Sigma-Aldrich). For immunohistochemistry using anti-Sox9 and anti-Sox10 antibodies, sections were incubated in antigen retrieval solution (10 mM citrate, pH 6.0) for 30 min at 70℃ before the incubation with primary antibodies. Antibodies used here were as follows: anti-NeuN antibody (Cell Signaling Technology), anti-Sox9 antibody (R&D systems), anti-Sox10 antibody (Santa Cruz Biotechnology), anti-Pax6 antibody (Millipore), anti-Tbr2 antibody (R&D systems), secondary antibodies conjugated with Alexa Fluor 647 (Molecular Probe), and secondary antibodies conjugated with Cy3 (Jackson ImmunoResearch).

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.
