表達(dá)區(qū)間及表達(dá)系統(tǒng)（Source）

Biotinylated Human Sortilin Protein, His,Avitag (SON-H82E9) is expressed from human 293 cells (HEK293). It contains AA Ser 78 - Asn 755 (Accession # Q99523-1).

Predicted N-terminus: Ser 78

蛋白結(jié)構(gòu)（Molecular Characterization）

This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag?).

The protein has a calculated MW of 79.3 kDa. The protein migrates as 90-100 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

標(biāo)記（Labeling）

Biotinylation of this product is performed using Avitag? technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.

蛋白標(biāo)記度（Protein Ratio）

Passed as determined by the HABA assay / binding ELISA.

內(nèi)毒素（Endotoxin）

Less than 1.0 EU per μg by the LAL method.

純度（Purity）

>95% as determined by SDS-PAGE.

制劑（Formulation）

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