Description
This Mouse Retinol Binding Protein 4 ELISA Kit is intended for quantitative detection of mouse RBP4 in cell culture supernates, serum, plasma (heparin, EDTA) and urine. Strip well format. Reagents for up to 96 tests.
This mouse RBP4 ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from rat specific for RBP4 has been precoated onto 96-well plates. Standards (NSO, E19-L201) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for RBP4 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the mouse RBP4 amount of sample captured in plate.
The capture antibody is a monoclonal antibody from rat, the detection antibody is a biotinylated polyclonal antibody from goat. Expression system for standard: Retinol binding protein 4, plasma, also known as RBP4, belongs to the lipocalin family and is the specific carrier for retinol (vitamin A alcohol) in the blood. It is protein that it is encoded by the RBP4 gene. RBP4 gene resides just centromeric of the cluster of CYP2C genes on 10q24. The mouse Rbp4 locus is closely linked and just proximal to the locus for phenobarbital-inducible cytochrome P450-2c (Cyp-2c) at the distal end of chromosome 19. It delivers retinol from the liver stores to the peripheral tissues. In plasma, the RBP-retinol complex interacts with transthyretin, which prevents its loss by filtration through the kidney glomeruli. A deficiency of vitamin A blocks secretion of the binding protein posttranslationally and results in defective delivery and supply to the epidermal cells. The standard product used in this kit are recombinant mouse B7-1/CD80, D37—K245, consisting of dimer acids with two single straned. The standard used in this kit is recombinant protein, with E19-L201 aa sequence, the molecular weight is 22kda
