We know how important it is to your research to have access to antibodies specific for your model. As it is often impossible to know which antibody will work best for a specific sample and application, we now offer SuperNovus Packs. These packs include different antibodies to the same protein to give you the ability to decide for yourself. The SuperNovus Packs are all offered at a discount price compared to purchasing each antibody individually. High density lipoproteins (HDLs) play a critical role in cholesterol metabolism and their plasma concentrations are inversely correlated with risk for atherosclerosis. The Scavenger Receptor, Class BI (SR-BI) binds HDLs and mediates selective uptake of HDL cholesteryl ester. SR-BI binds HDL with high affinity, is expressed primarily in liver and nonplacental steroidgenic tissues, and mediates selective cholesterol uptake by a distinct mechanism. In mice, it seems that SR-BI plays a key role in determining the levels of plasma lipoprotein cholesterol and the accumulation of cholesterol stores in the adrenal gland.
