Background Information
CD68 is a type I transmembrane glycoprotein that is highly expressed by human monocytes and tissue macrophages. It belongs to the lysosomal/endosomal-associated membrane glycoprotein (LAMP) family and primarily localizes to lysosomes and endosomes with a smaller fraction circulating to the cell surface. CD68 is also a member of the scavenger receptor family. It may play a role in phagocytic activities of tissue macrophages.

Reviews
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
FH Cohen (Verified Customer) (06-02-2025)  | Received a generous test sample of 20ul which stretched far. While the suggested dilutions ranged from 1/3000 to 12000, I found that 1/3000 was optimal for human adipose tissue and ectopic endometrial tissue. This is very impressive for a primary antibody, in my experience.
