Test principle : This assay employs a two-site sandwich ELISA to quantitate RBP in samples. An antibody specific for RBP has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyRBP present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conj µgated antibody specific for RBP is added to the wells. After washing, Streptavidin conj µgated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of RBP bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview : Retinol binding protein (RBP) 4 is the only specific transport protein for vitamin A in the circ µLation whose function is to deliver vitamin to target tissues. In obesity and type 2 diabetes, expression of Glut4 is significantly impaired in adipocytes. Glucose transport via Glut4 is the rate-limiting step for glucose use by muscle and adipose tissue.Yang et al. noted that adipocytespecific deletion of Gluts led to notable elevation of RBP4 causing systemic ins µLin resistance, and that reduction of RBP4 improved ins µLin resistance. This identified a novel role of RBP4 in reg µLating ins µLin action and RBP4 is recorded as an adipocytederived hormone. Thus, measurement of serum or plasma RBP4 is a usef µL means for understanding of metabolic disorders.
Stability : The stability of ELISA kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. The loss rate was determined by accelerated thermal degradation test. Keep the kit at 37°C for 4 and 7 days, and compare O.D.values of the kit kept at 37°C with that of at recommended temperature. (referring from China Biological Products Standard, which was calc µLated by the Arrhenius equation. For ELISA kit, 4 days storage at 37°C can be considered as 6 months at 2 - 8°C, which means 7 days at 37°C equaling 12 months at 2 - 8°C).
