In Western blot, a band is observed at ~70-80 kDa. The theoretical molecular weight of CD36 is ~53 kDa. The difference in theoretical MW and actual MW, as seen in Western blot, is most likely due to the heavy glycosylation and palmitoylation of this protein.
Theoretical MW
110 kDa. Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Background
Originally discovered in platelets, cluster of differentiation 36, CD36, (also known as thrombospondin receptor, fatty acid translocase (FAT), platelet membrane glycoprotein IV (GPIV), and scavenger receptor class B, member 3 (SR-B3)) is a plasma membrane glycoprotein belonging to the class B scavenger receptor family (1,2). Human, mouse, and rat CD36 is synthesized as a 472 amino acid (a.a.) protein with a theoretical molecular weight of 53 kDa for the canonical isoform (3). Its domains include a short cytoplasmic tail at the N-terminal and C-terminal and a large extracellular loop flanked on each side by a transmembrane domain. The extracellular domain facilitates the update of fatty acids (FFAs), phospholipids, and cholesterol by forming two hydrophobic cavities, which was first modeled in the CD36 homologue, LIMP-2/ SCARB2 (4).
The expression of CD36 has been reported in platelets, erythrocytes, monocytes, differentiated adipocytes, skeletal muscle, mammary epithelial cells, spleen cells, some skin microdermal endothelial cells, and in cancer. Circulating levels of soluble CD36 (sCD36) has also been reported in chronic inflammatory disease such as type 2 diabetes and chronic kidney disease. CD36 participates in angiogenesis, innate immunity, and the clearance of apoptotic phagocytes. In lipid metabolism, CD36 functions as a macrophage receptor for oxidized LDL and as an adipocyte receptor/transporter for long-chain FFAs. Plasmodium falciparum, the parasite that causes malaria, binds CD36 via PfEMP1 proteins, tethering parasite-infected erythrocytes to endothelial receptors (5). Anti-CD36 isoantibodies have been detected in Type 1 CD36-deficient mothers and is implicated as the cause of fetal/neonatal alloimmune thrombocytopenia (6).

Details: CD36/SR-B3 antibody was used for WB application on lysates of liver tissue from rats that were fed different diet regimns as - normal diet control/NC, high-fat diet control/HC or HC+ MLB/Magnesium lithospermate B (MLB5-20/HC+5-20?mg/kg/day of MLB). Primary antibody was used at 1:1000 dilution in 5% skim milk and detected with HRP-conjugated secondary antibody - chemiluminescent HRP substrate (data shown in Fig. 4A).
