Product overview

Human V-set and immunoglobulin domain-containing protein 4 (VSIG4) ELISA Kit (Catalog No. SL4226Hu) is an enzyme-linked immunosorbent assay kit for detection of the target in Serum, plasma, cell culture supernatants, body fluid and tissue homogenate.

Assay principle

This ELISA kit uses Sandwich-ELISA as the method. The Microelisa stripplate provided in this kit has been pre-coated with an antibody specific to VSIG4. Standards or samples are added to the appropriate Microelisa stripplate wells and combined to the specific antibody. Then a Horseradish Peroxidase (HRP)-conjugated antibody specific for VSIG4 is added to each Microelisa stripplate well and incubated. Free components are washed away. The TMB substrate solution is added to each well. Only those wells that contain VSIG4 and HRP conjugated VSIG4 antibody will appear blue in color and then turn yellow after the addition of the stop solution. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm. The OD value is proportional to the concentration of VSIG4. You can calculate the concentration of VSIG4 in the samples by comparing the OD of the samples to the standard curve.
