gene id	Uniprot ID: O95750
alias	Fibroblast growth factor 19, FGF-19, FGF19
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 20mM Tris-HCl, 150mM NaCl, 1mM EDTA, pH 8.0.
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.
shipping	Shipped at ambient conditions.
storage	Lyophilized form is stable for 1 week at room temperature. Store at -20 °C to -80 °C for 12 months in lyophilized form. After reconstitution, store at 4 °C for 2-7 days or at below -20 °C for up to 3 months.
