TMPRSS2 Fluorogenic Assay Kit 返回列表頁

The TMPRSS2 Fluorogenic Assay is a homogeneous assay that takes advantage of a specific fluorogenic substrate which emits fluorescence upon cleavage by the protease. Only one step is required to assess TMPRSS2 activity: TMPRSS2 protease is incubated with the fluorogenic substrate and fluorescence is measured using a plate reader (λex = 383 nm, λem = 455 nm). Camostat, a known TMPRSS2 inhibitor, is supplied as a protease inhibitor control.

Figure: Illustration of the principle behind the fluorogenic TMPRSS2 protease assay. The peptide substrate is labeled with a fluorophore on one end and an acceptor on the other end. The fluorescence emitted by the donor fluorophore is quenched due to the proximity of the acceptor in the intact peptide. The protease cleaves the peptide and generates a highly fluorescent peptide fragment.
