This document describes the recombinant human TGF‑β2 protein (GMP‑TL645) produced by Beijing T&L Biological Technology. The protein is expressed in human HEK293 cells and includes a C‑terminal Fc tag. It is intended for research use only and provides information on its sequence, molecular weight, purity, endotoxin level, biological activity and mechanism of action.
Key specifications include a predicted molecular weight of 42.1 kDa, purity of ≥95 % (SDS‑PAGE and HPLC), endotoxin ≤0.01 EU/µg, and an ED50 ≤0.5 ng/mL for inhibition of IL‑4‑dependent HT‑2 cell proliferation. The lyophilized product is stable for 24 months at 4 °C, and the reconstituted solution can be stored at –20 °C for 6‑12 months, avoiding repeated freeze‑thaw cycles. This manual is written in Chinese.
