Applications
Porcine liver esterase is used to catalyze the hydrolysis of pentaacetyl catechin and epicatechin for use in pharmaceutical and industrial applications. Pig liver esterase is commonly used for kinetic resolutions and assymetric synthesis in organic chemistry. Esterase from porcine liver has been used in a study to assess the effect of 5-aminolaevulinic acid peptide prodrugs on photosensitization for photodynamic therapy. Esterase from porcine liver has also been used in a study to investigate how site-specific atherogenic gene expression correlates with subsequent variable lesion development in coronary and peripheral vasculature. The enzyme from Creative Enzymes has been immobilised in hollow fibre ultrafiltration membrane and used for the asymmetric hydrolysis of a meso-diester. Esterase from Creative Enzymes has been used to investigate its effect on the release of methacrylic acid (MAA) and 2-hydroxyethyl methacrylate (HEMA) from adhesives formulated under conditions simulating wet bonding. It has been used to examine the ability of carboxylesterase activity to remove permethrin-and bifenthrin-ass ociated toxicity to Ceriodaphnia dubia and Hyalella azteca in a variety of matrices.
