蛋白结构(Molecular Characterization)

Online(Cys 24 - Glu 189) P01562-1

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.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>95% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

背景(Background)

Interferon alpha-1 is also known as IFN-alpha-1/13, Interferon alpha-D, LeIF D and IFNA1, belongs to the alpha / beta interferon family. Interferons alpha-1 and alpha-13 have identical protein sequences. Produced by macrophages, IFN-alpha have antiviral activities. Interferon stimulates the production of two enzymes: a protein kinase and an oligoadenylate synthetase. IFN-alpha can either suppress or promote the development of autoimmune diabetes. It is likely that IFN-alpha plays a complex role in the etiology of type 1 diabetes.
