Description
Prokineticin-1 functions as a potent angiogenic mitogen structurally related to VEGF, making it a critical tool for dissecting endocrine-gland vascular biology and tumor angiogenesis signaling. This tag-free recombinant protein spans the full mature sequence (residues 20–105) and demonstrates robust bioactivity, with an ED50 below 2.0 μg/ml in bovine EJG cell proliferation assays corresponding to a specific activity exceeding 500 IU/mg — data that supports use in cell proliferation and survival assays, angiogenesis models, and receptor-ligand binding studies via ELISA or SPR. The E. coli expression system yields a non-glycosylated form that provides a well-defined baseline for experiments where glycosylation-independent PROKR1/PROKR2 signaling is under investigation. Purity exceeding 98% by SDS-PAGE combined with endotoxin levels below 1.0 EU/μg satisfies the criteria typical for sensitive in vivo tumor biology models and primary cell-based wound healing assays.
