特异性
Optimal preservation of protein structure, post-translational modifications and functions.
产品特性
Recombinant human Interleukin-7 / IL7 protein expressed in Insect cells.
Produced with end-sequenced ORF clone
Tested for bioactivity.
纯度
> 95 % , as determined by Coomassie stained SDS-PAGE.
内毒素水平
Less than 0.01 ng per μg protein as determined by the LAL method.
Biological Activity Comment
The ED50 is 1.0 - 5 ng/ml, corresponding to a specific activity of 0.2 - 1 x 10^6 units/mg, determined by PHA activated PBL proliferation induced by IL-7 in a dose dependent manner. Under this condition the bioactivity is equivalent
