Lyophilized powder.

Formulation
Lyophilized after extensive dialysis against PBS.

Endotoxin Level
<0.2 EU/μg, determined by LAL method.

Reconstitution
Reconstitute the lyophilized recombinant Human Transforming Growth Factor alpha (rHuTGF-α) to 100 µg/mL using ddH2O or diluted with PBS.

Storage & Stability
Lyophilized recombinant Human Transforming Growth Factor alpha (rHuTGF-α) is stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping
Room temperature in continental US; may vary elsewhere.

Background
Transforming growth factor alpha (TGF-α) is a principal molecule in the normal and neoplastic development of the mammary gland. Binding of TGF-α to the epidermal growth factor receptor (EGFR), activates the EGFRs' endogenous tyrosine kinase activity and stimulates growth of the epithelium in the virgin and pregnant mouse mammary gland. TGF-α expression can be detected in breast cancer cells in vivo and in vitro and overexpression can elicit partial transformation or immortalized human and rodent mammary epithelial cells[1][2].
