Recombinant Human CD28 Protein, Fc-tagged, Alexa Fluor 647 conjugated

• Cat.No.: CD28-3909HAF647
• Product Overview: Alexa Fluor 647 conjugated recombinant human CD28 (P10747-1) isoform 1 extracellular domain (Met 1-Pro 152), fused with the Fc region of human IgG1 at the C-terminus, was produced in Human Cell.

Specification

• Species: Human
• Source: HEK293
• Tag: Fc
• Protein Length: 375
• Form: Lyophilized
• Molecular Mass: The recombinant human CD28/Fc is a disulfide-linked homodimeric protein. The reduced monomer consists of 375 amino acids and predictes a molecular mass of 42 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rhCD28/Fc monomer is approximately 55-65 kDa due to glycosylation.
• Endotoxin: < 1.0 EU/ μg of the protein as determined by the LAL method.
• Characteristic: Disulfide-linked homodimer
  Labeled with Alexa Fluor 647 via amines
  Excitation = 650 nm
  Emission = 668 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 PBS, pH 7.4
• 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.
