An assay is an investigative procedure in laboratory medicine, pharmacology, environmental biology, and molecular biology for qualitatively assessing or quantitatively measuring the presence or functional activity of the analyte, or the entity being targeted by the assay. Generally, assays involve biological materials or phenomena which tend to be intrinsically more complex in composition or in behavior than what can be handled by traditional chemical analysis and titration.

ROS Detection assay kit
Supplier: OZ BIOSCIENCES
ROS Detection Assay Kit is a cell-based assay designed for measuring Reactive Oxygen Species (ROS) activity within a cell using the cell-permeable fluorogenic probe 2', 7'-Dichlorodihydrofluorescein diacetate (DCF-DA). Once DCF-DA has diffused into cells it is deacetylated by cellular esterases to a non-fluorescent compound and rapidly oxidised by ROS into DCF. DCF is highly fluorescent and can be detected by microscopy, titration in microplate and also cytometry (ex 485/em 535). The fluorescence intensity that results is proportional to the ROS levels within the cell.

VWR® Protein Precipitation Kit
Supplier: VWR Chemicals
The Protein Precipitation Kit utilises a simple trichloroacetic acid (TCA) based method to precipitate proteins in complex mixtures. Only protein in the sample is pelleted, while interfering salts and surfactants remain in the supernatant. A gentle acetone wash removes TCA and co-precipitants allowing the end-user to recover the protein in a small volume of buffer.

Apoptosis and necrosis quantitation kits
Supplier: Biotium
Apoptosis and necrosis are two processes by which cells die. Apoptosis is an active, regulated disassembly of the cell from within. During apoptosis, phosphatidylserine is translocated from the inner to the outer surface of the cell, allowing the dying cell to be engulfed by phagocytic cells. Annexin V is a 35 kD Ca2+-dependent phospholipid binding protein with a high affinity for phosphatidylserine.

Pierce™ BCA™ Protein assay kits and reagents
Supplier: Thermo Fisher Scientific
Pierce BCA™ (bicinchoninic acid) reagents provide accurate determination of protein concentration with most sample types encountered in protein research. The Pierce BCA™ Protein Assay can be used to assess yields in whole cell lysates and affinity-column fractions, as well as to monitor protein contamination in industrial applications. Compared to most dye-binding methods, the BCA™ Assay is affected much less by protein compositional differences, providing greater protein-to-protein uniformity.
