Human PFN1 (Profilin 1) Microsample ELISA Kit

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human PFN1. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human PFN1. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Human PFN1, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Human PFN1 in the samples is then determined by comparing the OD of the samples to the standard curve.Detection Range: 78.13-5000 pg/mL. Sensitivity: 32 pg/mL. Assay Type: Sandwich. Standard: 5000 pg/mL. Sample Type: stissue homogenates, cell lysates and other biological fluids. Assay duration: 3.5h. Protein Function: Binds to actin and affects the structure of the cytoskeleton. At high concentrations, profilin prevents the polymerization of actin, whereas it enhances it at low concentrations. By binding to PIP2, it inhibits the formation of IP3 and DG. Inhibits androgen receptor (AR) and HTT aggregation and binding of G-actin is essential for its inhibition of AR [The Uniprot Consortium]
