PSGL-1 mediates leukocyte rolling and tethering to activated endothelium through high-affinity interactions with P-selectin, a process central to immune surveillance and cancer metastasis. This recombinant fragment spanning residues 18–320 captures the functionally critical N-terminal region and demonstrates robust binding activity in functional ELISA, achieving an EC50 of 2.420–2.733 ng/mL against anti-SELPLG antibody when immobilized at 2 μg/mL—quantitative evidence that supports its use in selectin-ligand binding studies and antibody development workflows. Mammalian expression preserves the native glycosylation and post-translational modifications essential for physiologically relevant selectin recognition, enabling researchers to model leukocyte adhesion dynamics in cell migration assays and investigate PSGL-1's role in tumor metastasis. The protein meets quality thresholds commonly required for functional assays, with purity exceeding 90% by SDS-PAGE and endotoxin levels below 1.0 EU/μg, criteria that align with standards expected in cell-based adhesion and invasion experiments.
