Recombinant Human Siglec-2/CD2

Recombinant Human Siglec-2/CD22  (CC03)

产品说明(Description)

Recombinant Human B-cell Receptor CD22 is produced by our Mammalian expression system and the target gene encoding Asp20-Arg687 is expressed with a 6His tag at the C-terminus. 

Accession #: P20273

Known as: B-cell receptor CD22; BL-CAM; B-lymphocyte cell adhesion molecule; CD22 antigenMGC130020; CD22 molecule; CD22; sialic acid binding Ig-like lectin 2; Siglec-2; SIGLEC2FLJ22814; T-cell surface antigen Leu-14

 

制剂(Formulation)

Lyophilized from a 0.2 μm filtered solution of PBS,1mM EDTA,pH7.4.

 

质量控制(Quality Control) 

Purity:        Greater than 95% as determined by reducing SDS-PAGE.    

Endotoxin: Less than 0.1 ng/ug (1 EU/ug) as determined by LAL test.

Bioactivity-BLI:

 

Loaded Anti-Human Siglec-2 mAb-Fc(Cat#NC013) on Protein A Biosensor, can bind Human Siglec-2(Cat#CC03) with an affinity constant of 177.9nM as determined in BLI assay.	______	Loaded Anti-Human Siglec-2 mAb-Fc(Cat#NC013) on Protein A Biosensor, can bind Human Siglec-2(Cat#CC03) with an affinity constant of 177.9nM as determined in BLI assay.

 

复溶(Reconstitution)

Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
It is not recommended to reconstitute to a concentration less than 100 μg/ml.
Dissolve the lyophilized protein in distilled water.
Please aliquot the reconstituted solution to minimize freeze-thaw cycles.    

 

保存(Storage)

Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7°C for 2-7 days.Aliquots of reconstituted samples are stable at < -20°C for 3 months.
