BP000145-CYT-095: Recombinant Human Interleukin-2 (IL-2) Protein, HEK
Source: HEK-derived.
The specific activity was determined by the dose-dependent stimulation of the proliferation of mouse CTLL-2 cells (mouse cytotoxic T cell line) and is typically 0.2-2 ng/ml.
Purity: > 95% as obsereved by SDS-PAGE.BP000145-CYT-624: Recombinant Mouse Interleukin-2 (IL-2) Protein, His Tag
