Assays

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.

Pierce™ BCA™ Protein assay kits and reagents

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.

Live bacterial gram stain kit

Supplier: Biotium

Wheat germ agglutinin binds specifically to N-acetylglucosamine in the peptidoglycan layer of gram-positive bacteria. The Live Bacterial Gram Stain Kit contains wheat germ agglutinin (WGA) conjugated to CF™594 to stain the surface of gram-positive cells with red fluorescence. The kit also includes DAPI to stain the DNA of all bacteria with blue fluorescence. Gram-positive bacteria stained using this kit will show a fluorescent blue interior and fluorescent red cell surface, while gram-negative bacterial will be stained with blue fluorescence only.
