Description
Interleukin-7 is a critical regulator of T and B lymphocyte development, survival, and homeostatic proliferation, making precise recombinant sourcing essential for mechanistic immunology studies. This tag-free recombinant mouse IL-7 encompasses the full mature sequence (residues 26–154) and demonstrates exceptional signaling potency, with an ED50 below 0.2 ng/mL in murine 2E8 cell proliferation assays—corresponding to a specific activity exceeding 5.0 × 10⁶ IU/mg—providing a reliable basis for JAK/STAT signaling pathway dissection, thymocyte differentiation assays, and lymphocyte survival or apoptosis studies. Endotoxin levels below 1.0 EU/μg minimize LPS-driven artifacts that can confound immune cell functional readouts, supporting use in sensitive in vivo models of inflammation or infection as well as serving as a quantitative reference standard in cytokine detection assays. Purity exceeding 96% by SDS-PAGE, combined with this endotoxin profile, satisfies the quality criteria typical for primary T and B cell proliferation assays and antibody validation workflows including ELISA.
