Produktinformation: Active protein produced in the endosperm tissue of barley grain. This production system uses barley endosperm storage cell which is characterised by its biochemically inert environment and lack of endotoxins. The barley endosperm tissue has a very low protease activity in comparison to most other cellular organisms, resulting in the unique protein storage function of the seed, that can maintain the proteins, including recombinant proteins, intact for years. The recombinant product is Aminal and Serum-free and therefore void of any human or animal viral contaminants that could jeopardize your cell culture. The purified recombinant protein carries no pyrogenic or pro-inflammatory contaminants. The Endotoxin level is less than 0.005ng per µg of recombinant protein (0.05EU/µg). Recombinant human VEGF165 contains 165 amino acids and a 16 a.a. histidine-based tag for a total length of 181 a.a. and has a predicted molecular mass of 20.9 kDa. As a result of glycosylation, the recombinant protein migrates with an apparent molecular mass of 30 kDa in SDS-PAGE.
