CD244,2B4,SLAMF4,NKR2B4,NAIL,h2B4

表达区间及表达系统（Source）

Human 2B4, Llama IgG2b Fc Tag (2B4-H5256) is expressed from human 293 cells (HEK293). It contains AA Cys 22 - Arg 221 (Accession # Q9BZW8-2).

Predicted N-terminus: Cys 22

蛋白结构（Molecular Characterization）

This protein carries a llama IgG2b Fc tag at the C-terminus.

The protein has a calculated MW of 50.1 kDa. The protein migrates as 65-70 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素（Endotoxin）

Less than 0.01 EU per μg by the LAL method / rFC method.

纯度（Purity）

>95% as determined by SDS-PAGE.

制剂（Formulation）

Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, 25 mM Arginine, 150 mM NaCl, pH7.5 with trehalose as protectant.
