Zinc Assay Kits

Zinc assay kits are available from a number of suppliers to quantify the amount of zinc present in a biological sample. Zinc is a metallic element that is essential in many biological functions, including enzyme function, protein stability, signal transduction, gene expression, and regulation of apoptosis. Colorimetric zinc assay kits are available in which zinc binds to a ligand to produce a measurable absorbance wavelength maximum at 560 nm. Fluorometric zinc assays are based on a high-affinity probe, generating fluorescence that is directly proportional to the amount of zinc in the sample.
