AP20144PU-N Polyclonal Antibody to CYP7B1 (C-term) - Aff - Purified

Alternate names: 25-hydroxycholesterol 7-alpha-hydroxylase, Cytochrome P450 7B1, Oxysterol 7-alpha- hydroxylase Quantity: 0.1 mg Concentration: 0.5 mg/ml Background: P450 enzymes constitute a family of monooxygenase enzymes that are involved in the metabolism of a wide array of endogenous and xenobiotic compounds including cholesterol. CYP8B1 moderates the ratio of cholic acid over chenodeoxycholic acid to control the solubility of cholesterol. P450 cholesterol 7-hydroxylase, CYP7A1, is the rate limiting enzyme of bile acid synthesis in the liver, and its expression is mediated by the bile acid receptor FXR. CYP27A1 catalyzes vitamin D3 25-hydroxylation and is localized to the mitochondria in kidney and liver. CYP7B1 (oxysterol 7-α-hydroxylase) functions as an enzyme in the alternate bile acid synthesis pathway. Specifically, CYP7B1 metabolizes 25-and 27-hydroxycholesterol. The gene encoding human CYP7B1 maps to chromosome 8q21.3. Mutations in the CYP7B1 gene may cause a metabolic defect in bile acid synthesis characterized by elevated urinary bile acid excretion, severe cholestasis, cirrhosis and liver synthetic failure. Uniprot ID: O75881 NCBI: NP_004811 GeneID: 9420 Host: Goat Immunogen: Peptide with sequence C-YPDSDVLFRYKVKS, from the C Terminus of the protein sequence according to NP_004811.1. Format: State: Liquid purified IgG fraction. Purification: Ammonium Sulphate Precipitation followed by Antigen Affinity Chromatography using the immunizing peptide. Buffer System: Tris saline, pH~7.3 Preservatives: 0.02% Sodium Azide Stabilizers: 0.5% BSA Applications: Peptide ELISA: Detection Limit: 1/128000. Western blot: Preliminary experiments in Human Liver, Kidney and Prostate lysates gave no specific signal but low background (at antibody concentration up to 1µg/ml). Immunohistochemistry on Paraffin Sections: 3-6 µg/ml. In Paraffin Embedded Human Breast shows textured Cytoplasm staining in ductal epithelial cells. Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user. Specificity: This antibody recognizes CYP7B1.
