Active Recombinant Human CD22 protein, His-Avi-tagged, Biotinylated

• Cat.No.: CD22-273HB
• Product Overview: Biotinylated Recombinant Human CD22 protein(Asp 20 - Arg 687), fused with His and Avi tag, was expressed in HEK293.

Specification

• Species: Human
• Source: HEK293
• Tag: Avi&His
• Protein Length: Asp 20 - Arg 687
• Form: Lyophilized from 0.22 μm filtered solution in 20 mM MES, 150 mM NaCl, pH5.5, 10% trehalose.
• Bio-activity: Immobilized Biotinylated Human Siglec-2, His,Avitag at 1 μg/mL (100 μL/well) on streptavidin precoated (0.5 μg/well) plate can bind Monoclonal Anti-Human Siglec-2 Antibody, Human IgG1 with a linear range of 1-10 ng/mL.
• Molecular Mass: This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag).The protein has a calculated MW of 78.7 kDa. The protein migrates as 100-115 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
• Endotoxin: Less than 1.0 EU per μg by the LAL method.
• Purity: >95% as determined by SDS-PAGE. >90% as determined by SEC-MALS.
• Storage: For long term, the product should be stored at lyophilized state at -20°C or lower.Please avoid repeated freeze-thaw cycles. This product is stable after at:
  -20°C to -70°C for 12 months in lyophilized state; -70°C for 3 months under sterile conditions after reconstitution.
• 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.
