来源

Recombinant DNA expressed in Human Embryonic Kidney Cells (HEK293)

纯度

Greater than 95% as determined by SDS-PAGE by a combination of ion exchange and size exclusion chromatography
Endotoxin < 1 EU/µg

生物活性

Typically <0.5 ng/ml (15.6 pM), measured by its dose dependent stimulation of the proliferation of CTLL-2 cells

缓冲液

Phosphate buffered saline (PBS) containing 0.1% bovine serum albumin (BSA)

内毒素

< 1 EU/μg

纯度

> 95% as determined by SDS-PAGE

纯化方法

A combination of ion exchange and size exclusion chromatography
