Introduction
Platelet glycoprotein IV, also called CD36, is an integral membrane glycoprotein with diverse physiological roles. It is widely expressed on various cell types and belongs to the scavenger receptor family. As a multiligand pattern recognition receptor, CD36 interacts with numerous structurally distinct ligands. Moreover, it plays a crucial role in lipid metabolism, acting as a fatty acid translocase essential for the binding and cellular and tissue transport of long-chain fatty acids (LCFAs). CD36 is also implicated in the onset and progression of chronic inflammatory disorders like Alzheimer's disease and atherosclerosis. As an integral membrane protein, its primary function involves acting as a receptor for thrombospondin and collagen. Additionally, CD36 directly facilitates the cytoadherence of Plasmodium falciparum-parasitized erythrocytes.
Description
CD36, produced in Sf9 Insect cells, is a single, glycosylated polypeptide chain with 419 amino acids (30-439a.a.) and a molecular mass of 47.4kDa. However, its apparent size on SDS-PAGE is approximately 57-70kDa. This CD36 protein is expressed with a 6 amino acid His tag at the C-terminus and purified using proprietary chromatographic techniques.
Physical Appearance
A clear, colorless solution that has been sterilized by filtration.
Formulation
The CD36 protein solution is provided at a concentration of 1mg/ml and is prepared in a buffer consisting of phosphate-buffered saline (pH 7.4) and 10% glycerol.
Stability
For optimal storage, keep the entire vial at 4°C if it will be used within 2-4 weeks. For extended storage, freeze the product at -20°C. To ensure stability during long-term storage, adding a carrier protein (0.1% HSA or BSA) is highly recommended. Importantly, repeated freezing and thawing of the product should be avoided.
Purity
The purity of the CD36 protein is determined to be greater than 95.0% using SDS-PAGE analysis.
Synonyms
