Sample Type:Serum, plasma and other biological fluids.Intended Use:Sandwich ELISA, Double AntibodySensitivity:<46.875pg/mlRange:78.125-5000pg/mlSpecificity:HumanTest Principle:This BioAssay™ kit was based on sandwich enzyme-linked immune-sorbent assay technology. Anti-INT8 antibody was pre-coated onto 96-well plates. And the biotin conjugated anti-INT8 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. 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 INT8 amount of sample captured in plate. Read the O.D. absorbance at 450nm in a microplate reader, and then the concentration of INT8 can be calculated.Kit Components:Micro ELISA Plate (Dismountable), 8x12Lyophilized Standard, 2xvialSample/Standard dilution buffer, 20mlBiotin-detection antibody (Concentrated), 120ulAntibody dilution buffer, 10mlHRP-Streptavidin Conjugate (SABC), 120ulSABC dilution buffer, 10mlTMB substrate, 10mlStop solution, 10mlWash buffer (25X), 30mlPlate Sealer, 5xpiecesProduct Description, 1xcopyStorage and Stability:Store powder at 4°C liquid at -20°C.
