CD28-640MAF555
Optional Service: Optional requirements on this protein
Product Overview :
Alexa Fluor 555 conjugated recombinant Mouse CD28 precursor extracellular domain (Met 1-Lys 149) (NP_031668.3), fused with the polyhistidine-tagged Fc region of human IgG1 at the C-terminus, was produced in Human Cell.
Source :
HEK293
Species :
Mouse
Tag :
Fc/His
Form :
Lyophilized
Molecular Mass :
The recombinant mouse CD28/Fc is a disulfide-linked homodimer after removal of the signal peptide. The reduced monomer consists of 378 amino acids and has a predicted molecular mass of 43 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rm CD28/Fc monomer is approximately 55-60 kDa due to glycosylation.
Protein length :
378
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.
