Recombinant Human CD40 Protein, Fc/His-tagged, Alexa Fluor 488 conjugated

• Cat.No.: CD40-174HAF488
• Product Overview: Alexa Fluor 488 conjugated recombinant human CD40 extracellular domainhuman (Met 1-Arg193) (NP_001241.1), fused with the polyhistidine-tagged Fc region of human IgG1 at the C-terminus, was produced in Human Cell.

Specification

• Species: Human
• Source: HEK293
• Tag: Fc&His
• Protein Length: 421
• Form: Lyophilized
• Molecular Mass: The recombinant human CD40/Fc is a disulfide-linked homodimer. The reduced monomer consists of 421 amino acids and has a predicted molecular mass of 47.3 kDa. As a result of glycosylation, the apparent molecular mass of rhCD40/Fc monomer migrates with an apparent molecular mass of 55-60 kDa in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU/ μg of the protein as determined by the LAL method.
• Characteristic: Disulfide-linked homodimer
  Labeled with Alexa Fluor 488 via amines
  Excitation Wavelength: 488 nm
  Emission Wavelength: 515­-545 nm
• Stability: Samples are stable for up to 12 months from date of receipt at -70 centigrade.
• Storage: Store it under sterile conditions at -20 to -70 centigrade. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Storage Buffer: Lyophilized from sterile 100 mM Glycine, 10 mM NaCl, 50 mM Tris, pH 7.5
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution. Centrifuge the vial at 4 centigrade before opening to recover the entire contents.
