Growth Factors, Cytokines Storage: -20CShipping: Blue Ice
Human EGF is produced by genetically engineered yeast, and purified by sequential chromatography and reverse-phase HPLC. This polypeptide is identical to gamma-urogastrone, or equivalent to human.

Source:
EGF1-52

Biological Activity:
The mitogenic activity of human EGF is measured by the stimulation of 3H-thymidine incorporation into human foreskin fibroblast cells. In addition, EGF activity has been determined by a receptor-binding assay (RBA) using A-431 cells.

Storage and Stability:
Lyophilized powder may be stored at -20C. Reconstitute to with sterile dH2O or buffer, aliquot and store at -20C. Reconstituted product is stable for 6 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
Source: EGF1-52
Purity: Purified. 97% pure by N-terminal aa sequencing, aa composition, HPLC analysis, and SDS gel electrophoresis
Concentration: As reported
Form: Supplied as a lyophilized powder in PBS
