Specification

• Source: HEK293
• Species: Human
• Tag: His
• Predicted N Terminal: Arg 23 & Ile 23
• Form: Lyophilized from sterile PBS, pH 7.4, 5%~8% trehalose and mannitol.
• Bio-activity: 1. Measured by its ability to bind biotinylated recombinant human IL12RB1 in a functional ELISA. 2. Measured in a cell proliferation assay using Anti-CD28 and Anti-CD3-stimulated PBMC. The ED50 for this effect is typically 0.1-0.6 ng/mL.
• Molecular Mass: The recombinant IL12 heterodimer of human IL12A/IL12B comprises 525 (208 + 317) amino acids and has a calculated molecular mass of 60.2 (24 + 36.2) kDa. The apparent molecular mass of rh IL12 heterodimer is approximately 40 & 43 kDa respectively in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
• Purity: >95 % as determined by SDS-PAGE.
• Stability: Samples are stable for up to twelve months from date of receipt at -70ºC.
• Storage: Store it under sterile conditions at -20ºC~-70ºC. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.25 ug/ul. Centrifuge the vial at 4℃ before opening to recover the entire contents.
