Specificity
Natural and recombinant human TGF-beta 2
Subcellular Localization
Secreted.
Sample Type
Cell culture supeatants, Serum, Plasma
Assay Procedure Summary
Activate the sample
Cell culture supeatants: add activating reagent pro rata, i.e. add 20?l of Solution A into 100?l of sample, 10 min later, add 20?l of Solution B. PH 7.0-7.6.
Serum, plasma(heparin, EDTA or citrate): add activating reagent pro rata, i.e. add 20?l of Solution A into 40?l of sample, 10 min later, add 20?l 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.
Anticoagulant
heparin, EDTA or citrate
Activating Reagent
TGF beta 2 is mostly contained as inactive form in samples, please activate it before assay. Don't activate recombinant TGF beta 2. Solution A: 1N HCI: add 8.33ml of 12N HCI into 91.67ml of H2O. Solution B: 1.2N NaOH/0.5M HEPES: add 12ml of 10N NaOH and 11.9g HEPES into 75ml of H2O, add H2O to adjust volume to 100ml.

Protein Function
TGF-beta 2 has suppressive effects on interleukin-2 dependent T-cell growth.
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.
