分子别名（Synonym）

IFN-alpha 2a, IFNA2a, IFN-alpha 2 (alpha 2a), interferon alpha 2a

表达区间及表达系统（Source）

Human IFN-alpha 2a (R46K) Protein, Fc Tag (IFA-H5253) is expressed from human 293 cells (HEK293). It contains AA Cys 24 - Glu 188 (R46K) (Accession # P01563 (R46K)).

Predicted N-terminus: Cys 24

蛋白结构（Molecular Characterization）

This protein carries a human IgG1 Fc tag at the C-terminus.

The protein has a calculated MW of 45.7 kDa. The protein migrates as 48-55 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素（Endotoxin）

Less than 1.0 EU per μg by the LAL method / rFC method.

纯度（Purity）

>90% as determined by SDS-PAGE.

>95% as determined by SEC-MALS.

制剂（Formulation）

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
