BioAssay Systems' QuantiFluo™ Trypsin Inhibitor Assay Kit uses for evaluation of drugs and screening of potential inhibitors to trypsin proteases.

BioAssay Systems’ DUKI-100 Kit provides a convenient fluorimetric means to screen for potential urokinase inhibitors. In this assay, the fluorimetric substrate reacts with urokinase and an inhibitor will decrease the fluorescence at λex/em = 380/450 nm.

BioAssay Systems’ improved antioxidant capacity assay is based on the reduction of DPPH by antioxidant molecules in a sample, which results in a drop in absorbance at 517 nm. The antioxidant capacity can be quantified and expressed using a Trolox standard.

BioAssay Systems Developing & Manufacturing Assay Products in the San Francisco Bay Area since 2003

Parallel Artificial Permeability Assays (PAMPA) offer researchers a quick, inexpensive method of evaluating the gastrointestinal (GI) permeability of test compounds. BioAssay Systems’ PAMPA Kit provides all the necessary components to run a Parallel Artificial Permeability Assay.

BioAssay Systems triglyceride assay uses a single Working Reagent that combines triglyceride hydrolysis and glycerol determination in one step, in which a dye reagent is oxidized to form a colored product.

BioAssay Systems’ α-Amylase Inhibitor Screening Kit utilizes fluorescence polarization (FP), a highly reliable and robust technique that significantly reduces background matrix interferences, enabling the effective identification of potential α-amylase inhibitors.

BioAssay Systems’ DASN-100 Kit provides a convenient fluorimetric method to measure asparaginase activity in biological samples. In this assay, o-phthalaldehyde reacts with liberated ammonia where the increase in fluorescence at λex/em = 415/475 nm is directly proportional to enzyme activity.
