Product Description |
Recombinant Human Latent TGF beta 2/TGFB2 Protein is expressed from HEK293 with His tag at the N-Terminus.It contains Leu21-Ser414. |
Product Background |
Transforming growth factor beta(2) (TGF-beta(2)), a growth regulator of human lens epithelial cells (HLECs), also regulates the death of these cells. TGF-beta(2)-induced apoptosis in HLECs was preceded by an induction of reactive oxygen species (ROS) and a decrease in glutathione in the intracellular content, indicating that this factor induces oxidative stress in HLECs. |
