Anti-Macrosialin CD68 Antibody

CD68/SR-D1 antibody

Superstar antibody: Boster’s anti mouse CD68 antibody (PA1518) is among its top 10 bestselling antibodies, and one of the most cited mouse/rat CD68 antibodies on the market. Because of this antibody’s high demand, we have subsequently developed a rabbit monoclonal anti CD68 antibody (M00602-1) targetting a similar epitope.

High specificity: PA1518 reacts with murine macrosialin/CD68, and has been validated with Western blotting and confirmed its stellar specificity. CD68 is a highly glycosylated protein, and its expected western blot molecular weight is between 80kDa to 110kDa, depending on glycosylation level. PA1518’s observed MW in WB is near 90-100kDa. Testing on negative control tissues showed no significant bands (images available on request) or staining. See more info in the positive and negative control design section. Based on immunogen sequence homology, this antibody is not expected to cross react with other proteins from the LAMP family, which complies with QC testing observations.

Great for CD68 IHC: This antibody produces clean and specific immunobiological stains in both mouse and rat tissues. Our QC team has validated it on spleen and liver tissues of both mice and rats. Click product images for more details on experiment conditions.

More about CD68: CD68 is a cell surface marker often used to identify macrophages and other cell types in the monocyte lineage. It is a transmembrane protein that binds to electins and selectins and plays a role in macrophage homing movement.

Background of CD68/SR-D1

CD68 is a heavily glycosylated glycoprotein that is highly expressed in macrophages and other mononuclear phagocytes. Macrosialin, if not glycosylated, has the main sequence that consists of 354 amino acids with an expected molecular weight of 37.4 kD. CD68, which can be located in the cytoplasmic granules of a variety of blood cells and myocytes, can be detected via immunohistochemistry. It's particularly effective as a marker for monocytes, histiocytes, giant cells, Kupffer cells, and osteoclasts, all of which belong to the macrophage lineage. CD68 is expressed in tissue macrophages and to a lesser extent in dendritic cells. CD68 is involved in tissue macrophage phagocytic activities, as well as intracellular lysosomal metabolism and extracellular cell-cell and cell-pathogen interactions. It works by binding to tissue and organ-specific lectins or selectins, enabling macrophage subsets to be directed to specific locations. Macrophages may be able to crawl over selectin-bearing substrates or other cells if CD68 is rapidly recirculated from endosomes and lysosomes to the plasma membrane.

HPMA–Copolymer Nanocarrier Targets Tumor-Associated Macrophages in Primary and Metastatic Breast Cancer

The immunofluorescence detection of the CD68 was performed on tumor specimens using the Discovery XT processor to confirm the co-staining of macrophages with the HPMA copolymer P-Alexa647-FA. Using IF and confocal microscopy the P-Alexa647-FA signal within TAMs costained with CD68 from both primary and metastatic tumor tissue specimens.

A somatic mutation in erythro-myeloid progenitors causes neurodegenerative disease

Immunostaining for CD68, IBA1, YFP and phosphorylated (p)ERK demonstrated that microglial clusters represented the accumulation of EMP-derived (YFP+) pERK+ microglia. The pathophysiological consequences of a somatic BRAF(V600E) mutation in different haematopoietic lineages are markedly distinct. BRAF(V600E) expression in HSCs can cause a tumoral disease, but results in a neurodegenerative inflammatory disorder when expressed in EMP, thereby linking the pathophysiology of clonal and neurodegenerative disorders.

Protective effects of Longhu Rendan on chronic liver injury and fibrosis in mice

Authors: Guizhi Yang,Shengwen Li,Jiahua Jin,Yuanyuan Xuan,Liqin Ding,Minxia Huang,Jun Liu,Biye Wang, Tian Lan

This study aimed at assessing the effects of Longhu Rendan (LHRD), a Chinese traditional patent medicine, on liver fibrosis and its potential mechanism. Immunohistochemical staining of CD68 showed positive staining to investigate the effect of LHRD on hepatic inflammation in mice. CD68, which was used as the marker of Kupffer cells, was downregulated after the treatment of LHRD. Through the activation of Kupffer cells, TNF-α and IL-1β are produced and then amplified chronic liver inflammation leading to liver fibrosis and cirrhosis. This suggests that LHRD is a potential medicine for the treatment of liver fibrosis.

Schistosoma japonicum-derived peptide SJMHE1 promotes peripheral nerve repair through a macrophage-dependent mechanism

Authors:Ma Y,Wei C,Qi X,Pu Y,Dong L,Xu L,Zhou S,Zhu J,Chen X,Wang X,Su C

This study investigated whether helminths or helminth-derived molecules might have the potential to improve peripheral nerve repair. It was demonstrated that schistosome-derived SJMHE1 promoted peripheral myelin growth and functional regeneration via a macrophage-dependent mechanism and simultaneously increased the induction of M2 macrophages. The CD68 antibody from Bosterbio was used as the macrophage marker for this study. The findings indicated that schistosome-derived SJMHE1 enhances damaged peripheral nerve repair in a macrophage-dependent manner and concomitantly increases M2 macrophage polarization, highlighting the therapeutic potential of SJMHE1 for promoting peripheral nerve repair.

High-Fat Diet-Related Obesity Promotes Urethane-Induced Lung Tumorigenesis in C57BL/6J Mice.

Authors: Shi D,Wu J,Wu Y,Lin X,Xu C,Lian X.

The study aimed to investigate whether high-fat diet (HFD)-induced obesity influences the susceptibility to chemical-induced lung tumorigenesis, a HFD feeding condition was combined with a multi-dose urethane-induced lung tumorigenesis model using C57BL/6J mice. Lung tissue slices were incubated with antibodies against CD68 from Bosterbio for the IHC assay. The findings showed that the role of HFD-induced obesity on lung tumorigenesis was elucidated both in vivo and in vitro in this study, and highly expressed leptin mediated the activation of STAT3 pathway was likely involved in the mechanism.
