Anti-Macrosialin CD68 Antibody Picoband®, Carrier-free

About this product

<p class="text-grey mb-2"><strong>Superstar antibody:</strong> 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 href="/anti-cd68-rabbit-monoclonal-antibody-m00602-1-boster.html" target="_blank">a rabbit monoclonal anti CD68 antibody (M00602-1)</a> targetting a similar epitope.</p> <p class="text-grey mb-2"><strong>High specificity:</strong> 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. </p> <p class="text-grey mb-2"><strong>Great for CD68 IHC:</strong> 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.

It is a transmembrane protein that binds to electins and selectins and plays a role in macrophage homing movement.

Background

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 ed 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.

Concentration

Adding 0.2 ml of distilled water will yield a concentration of 500 μg/ml.

Form

Lyophilized

Reconstitution

Add 0.2ml of distilled water will yield a concentration of 500ug/ml.

Function

Could play a role in phagocytic activities of tissue macrophages, both in intracellular lysosomal metabolism and extracellular cell-cell and cell-pathogen interactions. Binds to tissue- and organ-specific lectins or selectins, allowing homing of macrophage subsets to particular sites. Rapid recirculation of CD68 from endosomes and lysosomes to the plasma membrane may allow macrophages to crawl over selectin-bearing substrates or other cells.

Components

Each vial contains 4mg Trehalose, 0.9mg NaCl and 0.2mg Na2HPO4.
