Anti-CSF1R (phospho Y699) Antibody

Rabbit polyclonal reagent from Antibodies.com specifically recognizes Colony Stimulating Factor 1 Receptor (CSF1R) when phosphorylated at tyrosine 699, a site within the receptor's activation loop that reports ligand-driven kinase activity. This selectivity makes the antibody useful in studies of macrophage and monocyte signaling, myeloid lineage differentiation, and downstream receptor tyrosine kinase cascades in human cells and tissues. The product is supplied as 200 µl of unconjugated IgG and has been validated for Western blot detection of the phospho-protein. For best stability, keep the vial refrigerated and store aliquots at -20 °C; avoid repeated freeze-thaw cycles. The reagent is intended for research use only.
