Human RBP-4 PharmaGenie ELISA Kit (SBRS1032)

Quantify Retinol Binding Protein 4 (RBP-4), a 21 kDa circulating carrier of retinol (vitamin A) secreted by hepatocytes and adipocytes, with this 96-assay immunoassay kit from Assay Genie. The kit processes cell culture supernatant samples and accommodates human specimen workflows. Within metabolic disease, obesity, type 2 diabetes, and renal function research programs where RBP-4 serves as an adipose-derived candidate biomarker, plasma-type specimens are processed in dedicated wells alongside serum-type specimens measured in parallel wells of the same plate run. All components are packaged together for in vitro research use, and absorbance readings are captured on a standard microplate reader following the enclosed protocol. Reagents are supplied in individually sealed vials, and the procedure accommodates standard laboratory workflows under the storage conditions specified in the product insert.
