Recombinant Human CD22 protein, C-hFc-His Tag
Product Description
Cat
IMP-2018
Official Symbol
CD22
Product Overview
Recombinant Human CD22 protein(20-687aa), fused with C-hFc-His Tag, was expressed in HEK293.
Expression System
HEK293
Species
Human
Tag
C-hFc-His Tag
Form
Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8% trehalose is added as protectants before lyophilization. Please see Certificate of Analysis for specific instructions.
Molecular Mass
The protein has a predicted molecular mass of 102.1 kDa after removal of the signal peptide. The apparent molecular mass of CD22-hFc-His is approximately 130-180 kDa due to glycosylation.
Protein length
20-687aa
Purity
The purity of the protein is greater than 95% as determined by SDS-PAGE and Coomassie blue staining.
Biological Activity
ELISA plate pre-coated by 2 μg/ml (100 μl/well) Human CD22, hFc-His tagged protein can bind Anti-CD22 Neutralizing antibody in a linear range of 3.2-400 ng/ml.
Storage
Store at -20°C to -80°C for 12 months in lyophilized form. After reconstitution, if not intended for use within a month, aliquot and store at -80°C (Avoid repeated freezing and thawing).Lyophilized proteins are shipped at ambient temperature.
Reconstitution
It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
