85-4558-59　Heparan Sulfate Proteoglycan (HSPG) BioAssay™ ELISA Kit (Human) 48Tests　356400

特徴

• The Heparan Sulfate Proteoglycan (HSPG) BioAssay™ ELISA Kit is a quantitative sandwich assay for the detection of HSPG in human serum, plasma and other biological fluids. Cell lysates and tissue homogenates, though not tested, may potentially be used as samples.
• Detection Range:0.313-20ng/ml
• Sensitivity:0.188ng/ml
• Precision:Intra-Assay: CV<8%Inter-Assay: CV<10%
• Assay Principle:The microtiter plate provided in this kit has been pre-coated with an antibody specific to HSPG. Standards and samples are added to the appropriate microtiter plate wells followed by a biotin-conjugated antibody specific to HSPG. Streptavidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain HSPG, Biotin-conjugated antibody and enzyme-conjugated Streptavidin complex will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulfuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of HSPG in the sample is then determined by comparing the O.D. of the sample to the standard curve.
