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. The apparent molecular weight of CD68 is larger than calculated molecular weight due to post-translation modification.

Reviews
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
FH Zach (Verified Customer) (09-12-2025) | The antibody works perfectly with liver samples of MASH mice, and pancreas samples of chronic pancreatitis mice.
|
FH Emma (Verified Customer) (11-29-2021) | Works well by IF on FFPE tissue with a Tris-EDTA antigen retrieval. Also works by IHC.

FH Fabio Henrique (Verified Customer) (01-17-2019) | Figure 1. IF of CD68 (red) in human spleen. Formalin-fixed paraffin-embedded human spleen tissue was used as positive control to probe for CD68. Heat-induced antigen retrieval was performed in sodium citrate buffer pH 6.0 + Tween20 at 0.5%. Tissue incubated at 96*C for 20 min inside the buffer. Permeabilization was done with washes of TBSTritonX 0.25% for 3x 5min and blocking was done in TBS 10% Goat serum, 1% BSA, for 1 hr at RT. Anti-CD68 was used at 1:200 in blocking buffer, overnight incubation at 4*C. Secondary antibody AlexaFluor 488 was used at 1:500 for 1 hr at RT. Imaged using a Nikon A1 confocal microscope. Figure 2: CD68 (red) and CD206 (green) in human primary macrophages polarized to M2-phenotype, encapsulated in 3D hydrogel (hyaluronic acid and collagen type 1). Staining was performed as described above, except primary (CD68) was used at 1:100 and secondary antibodies were used at 1:500.
