The CYP21A1 (Steroid 21-Hydroxylase) BioAssay™ ELISA Kit (Rat) is a quantitative sandwich assay for the detection of CYP21A1 in serum, plasma, tissue homogenates and other biological fluids.
Sensitivity:0.094ng/ml
Detection Range:0.156-10ng/ml
Specificity:This assay has high sensitivity and excellent specificity for detection of rat CYP21A1. No significant cross-reactivity or interference between CYP21A1 and analogues was observed.
Precision:Intra-Assay: CV<8%Inter-Assay: CV<10%
Test Principle:This ELISA kit employs the sandwich enzyme-linked immune-sorbent assay technology. Anti-CYP21A1 antibody was pre-coated onto 96-well plates. The biotin conjugated anti-CYP21A1 antibody was used as detection antibodies. The standards, test samples and biotin conjugated detection antibody were added to the wells subsequently, and washed with wash buffer. HRP-Streptavidin 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 toproduce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the CYP21A1 amount of sample captured in plate. Read the O.D. absorbance at 450nm in a microplate reader, and then the concentration of CYP21A1 can be calculated.
Storage and Stability:Store unopened kit at 4ºC; store at -20ºC once opened. Store unopened standard at 4°C; once reconstituted, store at 4°C for up to 12 hours or at -20°C for up to 48 hours. Store other components at 4°C. Kit is stable for 6 months after receipt. For maximum recovery of product, centrifuge the original vials after thawing and prior to removing the cap.
