Recombinant Human CTLA4 Protein, Fc/His-tagged, Alexa Fluor 555 conjugated

• Cat.No.: CTLA4-2233HAF555
• Product Overview: Alexa Fluor 555 conjugated recombinant human CTLA4 (NP_005205.2) extracellular domain (Met 1-Phe 162), 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: 374
• Form: Lyophilized
• Molecular Mass: The recombinant human CTLA4/Fc is a disulfide-linked homodimer. The reduced monomer consists of 374 amino acids and has a predicted molecular mass of 41.6 kDa. As a result of glycosylation, the apparent molecular mass of rh CTLA4/Fc monomer is approximately 50-55 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 555 via amines
  With an excitation and emission maximum of 555/565 nm, Alexa Fluor 555 can be efficiently excited using a 543 nm He-Ne laser line and detected under standard TRITC/Cy3 filters.
• 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.
