TGF-alpha hFc Chimera, Human

TGF-alpha hFc Chimera, Human

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 Introduction
Species Human
Protein Construction
hFc TGF-alpha (Val40-Ala89)_x000D_
Accession # P01135-1
N-term C-term
Purity > 95% as determined by Bis­Tris PAGE 
> 95% as determined by HPLC
Endotoxin Level Less than 1EU per μg by the LAL method.
Biological Activity Measured by its binding ability in a functional ELISA. Immobilized TGF-alpha hFc Chimera, Human at 0.2μg/ml (100μl/well) on the plate can bind Biotinylated Anti­TGF­alpha Antibody, hFc Tag. Test result was comparable to standard batch.
Expression System HEK293
Theoretical Molecular Weight 32.9 kDa
Apparent Molecular Weight Due to glycosylation, the protein migrates to 38-45 kDa based on Bis-Tris PAGE result.
Formulation Lyophilized from 0.22μm filtered solution in 50mM Tris,100mM NaCl (pH 8.0).
Reconstitution Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
Storage & Stability Upon receiving, the product remains stable up to 6 months at -20 °C or below. Upon reconstitution, the product should be stable for 3 months at -80 °C. Avoid repeated freeze-thaw cycles.
