Description
Transforming Growth Factor-beta2 (TGF-beta2) is a member of a superfamily of homologous, disulfide-linked, homodimeric proteins that regulate the proliferation and differentiation of normal and transformed cells. Human TGF-beta2 is a 25.0 kDa protein with each subunit containing 112 amino acid residues.
Product Specific Information
Reconstitution: We recommend a quick spin followed by reconstitution in water to a concentration of 50 ug/ml.
Storage: This solution can then be stored at 4°C for 1 month. It is recommended that further dilutions be made in PBS containing 2mg/ml albumin and stored at -20°C.
