Scientific Data Images for Human Protein Disulfide Isomerase/P4HB Antibody
Detection of Human Protein Disulfide Isomerase/P4HB by Western Blot.
Western blot shows lysates of PANC-1 human pancreatic carcinoma cell line and MCF-7 human breast cancer cell line. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human Protein Disulfide Isomerase/P4HB Monoclonal Antibody (Catalog # MAB4236) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for Protein Disulfide Isomerase/P4HB at approximately 57 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Protein Disulfide Isomerase/P4HB in HeLa Human Cell Line.
Protein Disulfide Isomerase/P4HB was detected in immersion fixed HeLa human cervical epithelial carcinoma cell line using Mouse Anti-Human Protein Disulfide Isomerase/P4HB Monoclonal Antibody (Catalog # MAB4236) at 25 µg/mL for 3 hours at room temperature. Cells were stained using the Northern-Lights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.
Detection of Human Protein Disulfide Isomerase/P4HB by Western Blot.
Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line and human peripheral blood mononuclear cells (PBMC). PVDF Membrane was probed with 2 µg/mL of Human Protein Disulfide Isomerase/P4HB Monoclonal Antibody (Catalog # MAB4236) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for Protein Disulfide Isomerase/P4HB at approximately 60 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.Applications for Human Protein Disulfide Isomerase/P4HB Antibody

Background: Protein Disulfide Isomerase/P4HB
P4HB (Prolyl 4-hydroxylase beta chain; also PDI) is a 60 kDa member of the protein disulfide isomerase family. As an intracellular homodimer, it forms a tetrameric complex with P4H alpha chains to form an active prolyl 4-hydrolyase. This catalyses the hydroxylation of proline in collagen. On the cell surface, it reduces disulfide bonds in HIV that allow the virus to fuse with CXCR4 and enter susceptible cells. Mature human P4HB is 491 amino acids (aa) in length. It contains two TRX domains (aa 25-134 and 368-475) plus an ER retention sequence (aa 505-508). There is one potential isoform that shows an 11 aa substitution for the first 162 amino acids. Over aa 18-505, human P4HB shares 94% aa identity with mouse P4HB.
