Anti-IGF1R (phospho Y1131) Antibody

Rabbit polyclonal antibody from Antibodies.com that selectively recognizes IGF1R when phosphorylated at tyrosine 1131 (Y1131), an activation-loop residue in the kinase domain of the insulin-like growth factor 1 receptor. This unconjugated IgG reagent is validated for Western Blot (WB) applications and reacts with human IGF1R. Provided in a 50 µl vial, the antibody supports research on IGF1R signaling dynamics, receptor autophosphorylation, and downstream pathways linked to cell proliferation, growth regulation, and oncology. The polyclonal format detects multiple epitopes around the phospho-Y1131 site, enabling reproducible readouts of activated receptor in cell lysates and tissue homogenates. Store at -20°C and aliquot to limit freeze-thaw cycles, preserving antibody binding activity for repeated use.
