Active Recombinant Human CD33 Protein, LIgG2b Fc-tagged, low endotoxin

• Cat.No.: CD33-342H
• Product Overview: Recombinant Human CD33 Protein, LIgG2b Fc-tagged, low endotoxin is expressed from human 293 cells (HEK293). It contains AA Asp 18 - His 259 (Accession # AAH28152.1). Predicted N-terminus: Asp 18. This protein carries a llama IgG2b Fc tag at the C-terminus. The protein has a calculated MW of 54.6 kDa. The protein migrates as 64-90 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Specification

• Bio-activity: Recombinant Human CD33 protein, LIgG2b Fc-tagged, low endotoxin at 5 μg/mL (100 μL/well) can bind Anti-CD33, Human IgG1 with a linear range of 0.078-1.25 μg/mL (QC tested).
• Molecular Mass: 54.6 kDa
• Endotoxin: Less than 0.01 EU per μg by the LAL method.
• Purity: >95% as determined by SDS-PAGE.
• Notes: Please avoid repeated freeze-thaw cycles.
• Stability: No activity loss is observed after storage at:
  4-8 centigrade for 12 months in lyophilized state;
  -70 centigrade for 3 months under sterile conditions after reconstitution.
• Storage: For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 mg/ml. Centrifuge the vial at 4 centigrade before opening to recover the entire contents.
