ProteSEEKER™ identifies specific types of proteases with a panel of twelve protease inhibitors and a sensitive colorimetric protease screening assay. ProteSEEKER™ allows researchers to screen their protein samples and establish which specific class of proteases are present and therefore design a highly specific protease inhibitor cocktail using the minimal number of protease inhibitors. Alternatively, ProteSEEKER™ can be used to test existing protease inhibitor cocktails and identify their inadequacies and therefore supplement in additional protease inhibitors.

Cell proliferation dyes diffuse passively into cells and covalently label intracellular proteins, resulting in long term cell labelling. They are non-fluorescent until they are hydrolysed by intracellular esterase's. The dyes then react with intracellular amines forming fluorescent conjugates that are retained in the cell. Immediately after staining, a single, bright fluorescent population will be detected by flow cytometry. With each cell division, daughter cells inherit roughly half of the fluorescent label, allowing the number of cell divisions that occur after labelling to be detected by the appearance of successively dimmer fluorescent peaks on a flow cytometry histogram compared to cells analysed immediately after staining. Staining is formaldehyde fixable.
