Introduction

Resistin also known as adipose tissue-specific secretory factor or C/EBP-epsilon-regulated myeloid-specific secreted cysteine-rich protein (XCP1) is a cysteine-rich protein that in humans is encoded by the RETN gene. The gene comprises 4 exons, the first of which is untranslated, and spans approximately 1,750 bp. The length of the resistin pre-peptide in human is 108 amino acid residues and in the Human and rat it is 114 aa; the molecular weight is ~12.5 kDa. Resistin is a cytokine whose physiologic role has been the subject of much controversy regarding its involvement with obesity and type II diabetes mellitus (T2DM).

Principle of the Assay  

This kit was based on sandwich enzyme-linked immune-sorbent assay technology. Anti-Resistin polyclonal antibody was pre-coated onto 96-well plates. And the biotin conjugated anti-Resistin polyclonal antibody was used as detection antibodies. The standards, test samples and biotin conjugated detection antibody were added to the wells subsequently, and wash with wash buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with wash buffer. TMB substrates were 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 Resistin amount of sample captured in plate. Read the O.D. absorbance at 450nm in a microplate reader, and then the concentration of Resistin can be calculated.
