The CNKSR1 (Connector Enhancer of Kinase Suppressor of Ras 1) BioAssay™ ELISA Kit (Human) is a quantitative sandwich assay for the detection of CNKSR1 in human serum, plasma and other biological fluids. Cell lysates and tissue homogenates, though not tested, may potentially be used as samples.
Sensitivity:0.188ng/ml
Detection Range:0.313-20ng/ml
Specificity:This assay has high sensitivity and excellent specificity for detection of human CNKSR1. No significant cross-reactivity or interference between CNKSR1 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-CNKSR1 antibody was pre-coated onto 96-well plates. The biotin conjugated anti-CNKSR1 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 to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the CNKSR1 amount of sample captured in plate. Read the O.D. absorbance at 450nm in a microplate reader, and then the concentration of CNKSR1 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.
