Chromogenic substrate assay test

WebThe chromogenic assay consists essentially in the measurement of the anti-FXa activity of the test preparation against the USP Heparin Sodium Reference Standard. All of the chromogenix heparin kits meet this specification. Antithrombin, FXa, and the chromogenic substrates from Chromogenix are suitable for the USP guidelines. The anti-FXa assays ... WebThe most common type of ELISA detection uses a colorimetric assay. Generally, horseradish peroxidase (HRP-) or alkaline phosphatase (AP-) conjugated antibodies are used in combination with a chromogenic substrate (eg, TMB) solution. This detection method uses absorbance to determine the readout and compares samples to each other …
