gene name	IGF2
gene id	Uniprot ID: P01344
alias	Insulin-Like Growth Factor II, IGF-II, Somatomedin-A, IGF2, PP1446
host species	Human
production host	E.coli
tags	None
purity	Greater than 95% as determined by reducing SDS-PAGE.

endotoxin	No endotoxin was detected in final prodcut using LAL method to the method's sensitivity level (< 1.0 EU/ug).
formulation	Lyophilized from a 0.2 um filtered solution of 5mM HAc, pH 3.0.
reconstitution	Reconstitute lyophilized powder with water to a concentration of no less than 100 ug/ml, solubilize at RT for 30 min with occasional gentle mixing. It is recommended that 0.1% of HSA be added as a carrier protein for long term storage.
