Product Description	Recombinant Human TGF-alpha Protein is expressed from HEK293 with hFc tag at the N-Terminus.It contains Val40-Ala89.
Product Background	Transforming growth factor-alpha (TGFA) has been proposed as a candidate gene in the etiology of nonsyndromic cleft lip with or without cleft palate (NS-CL/P) and of nonsyndromic cleft palate only (NS-CPO). Biologic support for a role of TGFA arises from its presence at high levels in the epithelial tissue of the medial edge of the palatal shelves at the time of shelf fusion in mice.
Product Category	Recombinant Protein

Target	TGF-alpha
Synonyms	ETGF; TGF-alpha; TGF type 1; TGFA
Gene/Protein ID	P01135-1
Species	Human
Exact Sequence	Val40-Ala89
Molecular Weight	The protein has a predicted MW of 32.9 kDa. Due to glycosylation, the protein migrates to 38-45 kDa based on Tris-Bis PAGE result.
