Anti-gp91-phox Antibody

Cytochrome b-245, beta polypeptide (chronic granulomatous disease), also known as CYBB and P91-PHOX, is a human gene encoding a glycoprotein.
Cytochrome b (-245) is composed of cytochrome b alpha (CYBA) and beta (CYBB) chain. It has been proposed as a primary component of the microbicidal oxidase system of phagocytes. CYBB deficiency is one of five described biochemical defects associated with chronic granulomatous disease (CGD). In this disorder, there is decreased activity of phagocyte NADPH oxidase; neutrophils are able to phagocytize bacteria but cannot kill them in the phagocytic vacuoles.

Detects gp91-phox, Mr 75 kDa. Depending on the type of lysate, the amount loaded, the gel and the blotting conditions, gp91-phox may run as a sharp band, Mr 75 kDa, or appear as a smear between 75-91 kDa.

Predicted to cross react with mouse.

KLH-conjugated, synthetic peptide corresponding to amino acids 548-560 of human gp91-phox (KQSISNSESGPRG). The immunizing sequence is identical in mouse, and it shares 11/13 sequence homology in bovine and 10/13 in porcine.

Anti-gp91-phox Antibody is an antibody against gp91-phox for use in WB.

Immunoprecipitation:
Not recommended.

Routinely evaluated by Western Blot on human neutrophil membranes.

Western Blot Analysis:
1-4 µg/mL of this lot detected gp91-phox in a HL60 membrane and RIPA cell lysate. A previous lot detected gp91-phox in human neutrophil membranes.

Varies. Depending on the type of lysate, the amount loaded, the gel and the blotting conditions, gp91-phox may run as a sharp band, Mr ~75 kDa, or appear as a smear between 75-91 kDa

Format: Purified

Protein A purified

Purified rabbit polyclonal IgG in buffer containing 0.07 M Tris-glycine, pH 7.4, 0.105 M NaCl, 0.035% sodium azide and 30% glycerol. Liquid at -20°C.

Stable for 1 year at -20°C from date of receipt.
For maximum recovery of product, centrifuge the vial prior to removing the cap.
Handling Recommendations: Upon first thaw, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance. Note: Variabillity in freezer temperatures below -20°C may cause glycerol containing solutions to become frozen during storage.

Control
Lung tissue, human neutrophil membrane, HL60 membrane and RIPA cell lysate.

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.
