Dyes and Labeling Reagents

This category comprises chemicals for permanent and temporary labeling of organelles, proteins, and other molecules. For example, this includes the covalent linkage of a target protein, such as an antibody, with a fluorescent dye/fluorophore, allowing detection of the target protein in microscopic experiments. For the purpose of detection, proteins can also be coupled with reporter enzymes (e.g. HRP) or radioactive isotopes. To facilitate the purification of a target protein, biotinylation followed by streptavidine affinity binding has proven to be effective.

Calcein AM
Calcein AM

Item number: Cay14948-1

Calcein AM is a cell-permeable dye that, upon entering live cells, is cleaved by intracellular esterases, leaving membrane-impermeant calcein (Cay-16221), a fluorescent indicator with absorption and emission maxima of 494 and 517 nm, respectively. It can be used as an indicator of cell viability, cell-cell...
