Description
KIT receptor signaling drives proliferation and survival in hematopoietic stem cells, mast cells, and multiple cancer types, making quantitative assessment of ligand binding and antibody interactions critical for therapeutic development. This mammalian-expressed extracellular domain (aa 26–520) demonstrates robust binding to its cognate ligand KITLG with an EC50 of 0.69–0.86 ng/mL and to anti-KIT antibody with an EC50 of 2.20–2.63 ng/mL in functional ELISA, providing validated performance for competitive inhibition assays, blocking antibody screening, and therapeutic antibody epitope mapping. The mammalian expression system supports native glycosylation and disulfide bond formation essential for conformational integrity in ligand-receptor interaction studies. With purity exceeding 95% by SDS-PAGE and endotoxin below 1.0 EU/μg, this protein meets the quality thresholds commonly required for surface plasmon resonance affinity characterization, biolayer interferometry kinetic analysis, and small-molecule inhibitor screening in oncology drug discovery programs.
