- Background
- Transforming growth factor-beta 2 (TGF-beta 2) is a secreted protein known as a cytokine that performs many cellular functions and has a vital role during embryonic development. This gene is mapped to 1q41. It is an extracellular glycosylated protein. It is known to suppress the effects of interleukin dependent T-cell tumors. TGF-beta 2 is present at elevated levels in the aqueous humor of patients with primary open angle glaucoma (POAG) . Studies have shown that TGF-beta 2 influences cultured trabecular meshwork cells, and it reduced outflow facility when perfused into cultured human anterior segments. In POAG, elevated expression of Gremlin by TM cells inhibited BMP4 antagonism of TGF-beta 2 and led to increased extracellular matrix deposition and elevated IOP.

- Sample Activation Procedure
- Activate the sample Cell culture supernatants: add activating reagent pro rata, i.e. add 20μl of Solution A into 100μl of sample, 10 min later, add 20μl of Solution B. PH 7.0-7.6. Serum, plasma (heparin, EDTA or citrate) : add activating reagent pro rata, i.e. add 20μl of Solution A into 40μl of sample, 10 min later, add 20μl of Solution B. PH 7.0-7.6. It is unnecessary to activate the recombinant TGF-beta 2. Sample was diluted partly after adding activating reagent, so please pay attention to this when calculate target protein concentration.
