Sample Type:Serum,plasma,tissue homogenates and other biological fluids.Intended Use:Sandwich ELISA,Double AntibodySensitivity:<0.281ng/mlRange:0.469-30ng/mlSpecificity:HumanTest Principle:This BioAssay kit was based on sandwich enzyme-linked immune-sorbent assay technology. Visfatin C termina antibody was pre-coated onto 96-well plates. And the biotin conjugated anti-Visfatin C termina 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 Visfatin C termina amount of sample captured in plate. Read the O.D. absorbance at 450nm in a microplate reader,and then the concentration of Visfatin C termina 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.
