Recombinant Human CD80 Protein, His-tagged, Alexa Fluor 555 conjugated

Specification :
| Source : HEK293 | Species : Human | Tag : His | Form : Lyophilized | Molecular Mass : The recombinant human B7-1 consists of 219 amino acids and has a predicted molecular mass of 25.4 kDa. By reduced SDS-PAGE, the apparent molecular mass of rh B7-1 is approximately 45-48 kDa due to glycosylation. | Protein length : 219 | Endotoxin : | Characteristic : Disulfide-linked homodimerLabeled with Alexa Fluor 555 via aminesWith 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.
