Activity Assay

The activity was measured by its ability to inhibit the IL-4 induced proliferation in mouse HT-2 cells (BALB/c spleen activated by sheep erythrocytes in the presence of IL-2).

Reconstitution

Briefly  centrifuge  the  vial  before  opening.  It  is recommended to reconstitute the protein in sterile 4 mM  HCl  containing  at  least  0.1%  human  or bovine serum albumin.

 

Stability & Storage

Use a manual defrost freezer and avoid repeated freeze-thaw cycles. In general: 12 months from date of receipt, -20 to -80°C as supplied. 1 month, 2 to 8°C under sterile conditions after reconstitution. 3 months, -20 to -80°C under sterile conditions after reconstitution.

 

Protein Description

Transforming growth factor beta 2 (TGF-β2) is one of three closely related mammalian members of the large TGFβ superfamily, TGF-β1, β2, and β3, signal through the same receptor and elicit similar biological responses.  TGF-β2 is expressed in keratinocytes, granulosa cells, astrocytes, osteoblasts, mammary cells, and various cancer cells. TGF-β2 is secreted and complexed with two other proteins, LAP and TGFBP, and requires proteolytic cleavage to be active. Human TGF-β2 is a secreted, homodimer linked by intermolecular disulfide bonds that plays a role in many cellular processes,including embryogenesis and angiostasis. TGF-β2 also plays an extensive role in prenatal development.
