Human IFN-alpha 1 Protein, His Tag
IFN-alpha 1,IFNA1,IFNalpha 1,IFN-alpha-1,LeIF D
Human IFN-alpha 1, His Tag is expressed from human 293 cells. It contains AA Cys 24 - Glu 189
Predicted N-terminus: Cys 24
Request for sequence
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 21.3 kDa. The protein migrates as 22-24 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Less than 1.0 EU per μg by the LAL method.
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
