Application

Cell Counting Kit or FCCK is used for the detection of live cells by fluorometric method.

Features and Benefits

Cell Counting Kit has the following advantages: It doesn't require any radioisotopes to function. No solubilization procedure is needed. Results are highly reproducible and accurate.

General description

Cell Counting kit, also known as FCCK, is a fluorescent cell counting product. The amount of a fluorescent dye, calcein, produced from Calcein-AM (3′,6′-Di(O-acetyl)-2′,7′-bis [N, Nbis-(carboxymethyl) aminomethyl]-fluorescein, tetraacetoxymethyl ester) by esterases in cells is directly proportional to the number of viable cells in a culture medium. Calcein-AM is highly lipophilic due to the presence of acetoxymethyl groups in the molecule, which rapidly permeates into the cell cytoplasm through the membrane.
