Description
The Boster One Step Picokine™ Human CST3 Pre-Coated ELISA (Enzyme-Linked Immunosorbent Assay) kit is a solid phase immunoassay specially designed to measure Human CST3 with a 96-well strip plate that is pre-coated with antibody specific for CST3. The detection antibody is a HRP conjugated antibody specific for CST3. The capture antibody is monoclonal antibody from mouse, the detection antibody is polyclonal antibody from goat. The kit contains recombinant Human CST3 with immunogen: Expression system for standard: NSO; Immunogen sequence: M1-A146. The kit is analytically validated with ready to use reagents.
To measure Human CST3, add standards and samples to the wells, then add HRP conjugated detection antibody. Wash the wells with PBS or TBS buffer, and add TMB. TMB is substrate to HRP and will be catalyzed to produce a blue color product, which changes into yellow after adding acidic stop solution. The density of the yellow product is linearly propotional to Human CST3 in the sample. Read the density of the yellow product in each well using a plate reader, and benchmark the sample wells’ readings against the standard curve to determine the concentration of Human CST3 in the sample.

Reproducibility
To assay reproducibility, three samples with differing target protein concentrations were assayed using four different lots.
