Size: 50µg

Catalogue Number: EPT091-50

Lead times: 1-2 weeks, if manufacturer has product in stock

Manufacturer/Ship Location: China

Background: Insulin-like growth factor I (IGF1) belongs to the family of insulin-like growth factors that are structurally homologous to proinsulin. Mature IGFs are generated by proteolytic processing of inactive precursor protein containing N-terminal and C-terminal propeptide regions. Mature human IGF-I consisting of 70 amino acids with 94% identity with mouse IGF1 and exhibits cross-species activity. IGF1 binds IGF-1R, IGF-2R, and the insulin receptor and plays a key role in cell cycle progression, cell proliferation and tumor progression. IGF1 expression is regulated by growth hormone.

Description: Recombinant Human Insulin-like Growth Factor I (4-70) is produced by our E. coli expression system and the target gene encoding Thr52-Ala118 is expressed.

Alternate Names: Insulin-Like Growth Factor I, IGF-I, Mechano Growth Factor, MGF, Somatomedin-C, IGF1, IBP1

Purity: Greater than 95% as determined by reducing SDS-PAGE.

Redissolve: Always centrifuge tubes before opening.Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100μg/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. 

Endotoxin: Less than 0.05 ng/µg (0.5 EU/µg) as determined by LAL test.

Molecular Weight: 7.3 KDa

Observed Molecular Weight: 9 KDa, reducing conditions

Storage: Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
