• Cat.No.: CD33-7815H
• Product Overview: Recombinant Human CD33(AAH28152.1)(Asp 18 - His 259), fused with His Tag, is expressed from human 293 cells (HEK293).

Specification

• Source: HEK293
• Species: Human
• Tag: His
• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
• Bio-activity: Immobilized Anti-Human CD33 MAb, Mouse IgG1 at 1 μg/mL (100 μL/well) can bind Human Siglec-3, His Tag with a linear range of 0.1-2 ng/mL.
• Molecular Mass: The protein has a calculated MW of 27.6 kDa. The protein migrates as 43-55 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
• Protein Length: Asp 18 - His 259
• 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 storage, the product should be stored at lyophilized state at -20 centigrade or lower.
  Please avoid repeated freeze-thaw cycles.
  This product is stable after storage at:
  -20 centigrade to -70 centigrade for 12 months in lyophilized state;
  -70 centigrade 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℃ before opening to recover the entire contents.
