Description
Galectin-1 plays a critical role in tumor immune evasion and T-cell apoptosis, making functionally validated protein essential for mechanistic cancer immunology studies. This tag-free recombinant human Galectin-1 (LGALS1), covering residues 2–135 of the mature protein, demonstrates potent chemotactic activity on human blood monocytes at 1.0–10 ng/ml, confirming its biological relevance for functional cell migration assays and immune cell recruitment experiments. Expression in *E. coli* preserves the native non-glycosylated state of this lectin, ensuring physiologically appropriate homodimer formation critical for β-galactoside binding studies. With purity exceeding 95% by SDS-PAGE and endotoxin levels below 1.0 EU/μg, this preparation satisfies the quality criteria typical for monocyte and T-cell functional assays, carbohydrate-binding studies, and tumor microenvironment modeling where endotoxin contamination would confound innate immune readouts.
