CD163 serves as a critical hemoglobin scavenger receptor expressed predominantly on monocytes and macrophages, where it mediates the clearance of hemoglobin-haptoglobin complexes from circulation. This receptor has emerged as a valuable marker for alternatively activated M2 macrophages, making it particularly relevant for researchers investigating tumor microenvironments, inflammatory conditions, and cardiovascular disease. The soluble form of CD163 has also gained attention as a biomarker for macrophage activation in various pathological states.
This recombinant monoclonal antibody, clone 26F9, offers the consistency and reliability that demanding research applications require. Developed using recombinant technology with a defined human IgG1 framework, this antibody provides sequence-defined specificity against human CD163, ensuring reproducible results across experiments and eliminating the lot-to-lot variability often encountered with traditional hybridoma-derived antibodies. The antibody was generated using recombinant human CD163 protein as the immunogen, supporting precise epitope targeting.
Validation studies demonstrate effective performance in immunohistochemistry applications, with testing conducted on paraffin-embedded human breast cancer tissue. Using a Leica Bond system with citrate buffer antigen retrieval, the antibody produced clear staining at dilutions ranging from 1:50 to 1:200, with successful detection observed at 1:300 dilution. This flexibility in working concentration allows researchers to optimize staining intensity for their specific tissue types and experimental conditions. The antibody is also validated for ELISA applications, expanding its utility across different experimental workflows.
For investigators studying macrophage biology, tumor-associated immune populations, or cardiovascular pathology, this CD163 antibody provides a reliable tool for characterizing tissue macrophage phenotypes in human samples.
