The RAB27B (Ras-Related Protein Rab-27B) BioAssay™ ELISA Kit (Human) is a quantitative sandwich assay for the detection of RAB27B 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 RAB27B. No significant cross-reactivity or interference between RAB27B 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-RAB27B antibody was pre-coated onto 96-well plates. And the biotin conjugated anti-RAB27B antibodywas 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 RAB27B amount of sample captured in plate. Read the O.D. absorbance at 450nm in a microplate reader, and then the concentration of RAB27B 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.
