Anti-CSFR (Ab-809) Antibody

Raised in rabbit against a peptide region encompassing residue 809 of human colony stimulating factor receptor (CSFR, also called CSF1R or CD115), this polyclonal antibody from Antibodies.com supports receptor-focused studies in myeloid cell biology. The reagent is supplied as 100 µl of unconjugated antisera in a single-use vial format, validated for western blot (WB), immunohistochemistry (IHC), and immunofluorescence (IF) applications on human tissue and cell preparations.

CSF1R is a receptor tyrosine kinase central to monocyte, macrophage, and osteoclast differentiation, and is widely investigated in tumor-associated macrophage biology, microglial activation models, and inflammatory disease research. Residue 809 lies within the intracellular kinase domain, making this antibody a useful tool for receptor localization and expression studies across formalin-fixed paraffin-embedded sections and cultured cell lysates. For storage, keep the vial at -20 °C in working aliquots to limit freeze-thaw cycles, allow brief equilibration to room temperature before use, and protect from light during handling. Pairing this reagent with appropriate secondary antibodies and isotype controls helps clarify receptor distribution patterns in normal and pathological samples.
