Synonyms

CD1d & B2M

Source

Biotinylated Human CD1d&B2M Monomer Protein (CDM-H82E9) is expressed from human 293 cells (HEK293). It contains AA Glu 20 - Ser 301 (CD1d) & Ile 21 - Met 119 (B2M) (Accession # P15813 (CD1d) & P61769 (B2M)).

Predicted N-terminus: Glu 20 & Ile 21

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 39.0 kDa and 15.7 kDa. The protein migrates as 50-55 kDa and 17 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

Labeling

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

Protein Ratio

Passed as determined by the HABA assay / binding ELISA.

Endotoxin

Less than 0.1 EU per μg by the LAL method / rFC method.

Purity

>90% as determined by SDS-PAGE.

>90% as determined by SEC-MALS.

Formulation

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