Overview:

This product is a lateral flow chromatographic test strip with two bands: a lower control line and an upper test line. Streptavidin (SA) is coated at the control line, and goat anti-mouse antibody is coated at the test line. Complete CAS system probes (labeled with both Biotin and FITC) can link all the colloidal gold to the control line. When a probe is cut by the CAS enzyme, the colloidal gold bound with the cut fragment will not be captured at the control line, resulting in the formation of the test line. The presence or absence of the test line indicates the activation of the CAS enzyme.
