Interleukin-3 drives multilineage hematopoietic cell survival and proliferation, making it indispensable for studies of myeloid differentiation, mast cell biology, and cytokine-dependent cell line maintenance. This tag-free protein, spanning the full mature sequence (aa 20–152), demonstrates robust bioactivity in TF-1 erythroleukemic cell proliferation assays with an ED50 of 0.02–0.1 ng/mL, providing quantitative evidence of receptor engagement at physiologically relevant concentrations. The low endotoxin specification (≤10 EU/mg) meets the quality thresholds commonly required for immune cell functional assays, including primary PBMC activation studies and JAK/STAT signaling pathway analyses, where LPS contamination would confound cytokine-specific responses. Purity exceeding 95% by SDS-PAGE, combined with the validated proliferative potency, supports use in antibody development workflows, cytokine detection assay standardization, and in vitro hematopoiesis models where precise dose-response relationships are critical.
