Application

Esterase Isoenzymes may be used to identify the monocytic element in normal and leukemic cells. They may be used for the biochemical characterization of different hematopoietic cell lineages and stages of differentiation when studying leukemias and lymphomas. Esterase Isoenzyme 1, product 43388, is recombinant and from porcine liver. It is expressed in E. coli.

Biochem/physiol Actions

An esterase is a hydrolase that splits esters into acids and alcohols.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Unit Definition

1 U corresponds to the amount of enzyme which converts 1 μmol 4-nitrophenyl-L-acetate per minute at pH 7.5 and 30°C.
