Overview
Anti-Macrosialin CD68 Antibody Picoband® is an antibody targeting CD68. Common applications include WB, IHC, IF, Flow Cytometry, ELISA. Key specifications include host: Rabbit; clonality: Polyclonal; isotype: Rabbit IgG; reactivity: Mouse,Rat; observed MW: 90-100 kDa; calculated MW: 34818 MW.
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.

The brand Picoband indicates this is a premium antibody that guarantees superior quality, high affinity, and strong signals with minimal background in Western blot applications. Only our best-performing antibodies are designated as Picoband, ensuring unmatched performance.Key elements and design rationale

Biological background
Protein function (datasheet): 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.
Scientific background (datasheet): 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.
Cellular localization (datasheet): Isoform Long: Endosome membrane; Single-pass type I membrane protein. Lysosome membrane; Single-pass type I membrane protein.
Tissue details (datasheet): Expressed in tissue macrophages and to a lesser extent in dendritic cells.
Sequence similarities (datasheet): Belongs to the LAMP family.
Research relevance and current trends
- Commonly studied in contexts related to Cell Type Markers,Immunology.
- Supports comparative expression analysis across conditions, genotypes, or treatments when paired with appropriate controls.
- Useful for confirming target presence and subcellular distribution using orthogonal readouts (e.g., microscopy vs. immunoblotting).
Common research applications
- Western blot (WB): Compare relative target abundance and apparent size/isoforms across samples; interpret bands in light of expected MW and potential PTMs.
- ELISA: Measure target abundance in compatible matrices using a standard-curve readout; ensure dilution linearity and appropriate controls.
- Immunohistochemistry (IHC): Assess tissue distribution and cell-type patterns; interpret staining with appropriate negative controls and antigen context.
- Immunofluorescence / ICC: Visualize subcellular localization and co-localization patterns; consider fixation/permeabilization compatibility and controls.
- Flow cytometry: Quantify target-positive populations in single-cell suspensions; pair with viability and isotype/FMO controls conceptually.
Notes for experimental interpretation
- Consider isoforms, post-translational modifications, and processing that can shift apparent molecular weight or localization.
- Cross-reactivity (datasheet): No cross-reactivity with other proteins
- Use appropriate positive and negative controls (e.g., KO/KD, blocking peptide, or isotype controls) to support specificity interpretation.
As a polyclonal antibody, this reagent may recognize multiple epitopes on the target, which can improve detection robustness but may require careful specificity controls.
