分子别名（Synonym）

Siglec-9,SIGLEC9,CDw329,CD329

表达区间及表达系统（Source）

Biotinylated Human Siglec-9, His,Avitag (SI9-H82E9) is expressed from human 293 cells (HEK293). It contains AA Gln 18 - Gly 348 (Accession # Q9Y336-1).

Predicted N-terminus: Gln 18

蛋白结构（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 39.6 kDa. The protein migrates as 60-70 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

标记（Labeling）

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

蛋白标记度（Protein Ratio）

Passed as determined by the HABA assay / binding ELISA.

纯度（Purity）

>95% as determined by SDS-PAGE.

制剂（Formulation）

Lyophilized from 0.22 μm filtered solution in 25 mM MES, 150 mM NaCl, pH5.5 with trehalose as protectant.
