Scientific Data Images for Human Protein Disulfide Isomerase/P4HB Antibody

Detection of Human Protein Disulfide Isomerase/P4HB antibody by Western Blot.

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 Goat Anti-Human Protein Disulfide Isomerase/ P4HB Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4236) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). 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 antibody in HeLa Human Cell Line by Immunocytochemistry (ICC).

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 Goat Anti-Human Protein Disulfide Isomerase/P4HB Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4236) at 1.7 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Detection of Human Protein Disulfide Isomerase/P4HB by Simple WesternTM.

Simple Western lane view shows lysates of PANC-1 human pancreatic carcinoma cell line and MCF-7 human breast cancer cell line, loaded at 0.2 mg/mL. A specific band was detected for Protein Disulfide Isomerase/P4HB at approximately 59 kDa (as indicated) using 10 µg/mL of Goat Anti-Human Protein Disulfide Isomerase/P4HB Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4236) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

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 hydroxylase. 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.
