产品特性
Recombinant human Interleukin 12b (Il12b) protein expressed in Sf9 cells.
Produced with end-sequenced ORF clone
Tested for bioactivity.
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 0.10 to 0.20 ng/ml, corresponding to a specific activity of 1.0 - 0.5 x 10^7 units/mg, determined by the dose dependent stimulation of IFN&gamma production by mouse splenocytes.
