Enzyme Activity Measurement of Lipoprotein Lipase

The outstanding reputation of Creative Enzymes as an enzyme service provider is built on both modern laboratory instruments and technical knowledge. Our laboratory services for enzyme activity measurement are endorsed by thousands of customers. We provide activity assays for lipoprotein lipase with the most suitable and efficient methods.

Lipoprotein lipase (LPL, EC 3.1.1.34) is first synthesized in the tissues and then transported to the surface of endothelial cells of the capillary beds where it presents the natural functions. LPL hydrolyzes chylomicrons and very low-density lipoproteins to release free fatty acids (FFAs), generates remnant lipoproteins, and gives rise to the formation of high-density lipoproteins (HDL). ApoC-II is an important cofactor for its catalysis activity.

Lipoprotein lipase exists widely in human bodies. It is distributed in adipose, heart, skeletal muscle tissue, as well as in lactating mammary glands. It participates in the metabolism of glycerolipid and it is a rate-limiting enzyme for the hydrolysis of triglyceride (TG)-rich lipoproteins. Changes in tissue lipoprotein lipase activities occur in response to a variety of conditions and are subject to hormonal control. In general, these activity variations correlate closely with changes in the rate of triacylglycerol uptake by tissues. The deficiency and overexpression of lipoprotein may lead to different diseases. For example, the activity deficiency causes hypertriglyceridemia, whereas overexpression of LPL may increase insulin sensitivity and promote obesity. Although the crystal structure has not been identified yet, this enzyme is always the hotspot on the researches. Due to the suggestive roles in many clinical diseases, the activity of lipoprotein lipase has become a key monitoring target in diagnosis. Creative Enzymes helps to determine the enzyme activity at protein levels. We can achieve activity measurement for enzymes in tissues, cells, plasmas, and stains. Our unparalleled professional advantage is strong back for the precise results.
