Active Recombinant Human IL12A & IL12B protein

• Cat.No.: IL12A & IL12B-357H
• Product Overview: Recombinant Human IL12A & IL12B protein(P29459-1 & NP_002178.2)(Met1-Ser219 & Met1-Ser328) was expressed in HEK293.

Specification

• Source: HEK293
• Species: Human
• Tag: N/A
• Form: Lyophilized from sterile PBS, pH 7.4.Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.
• Bio-activity: Measured by its ability to induce Interferon gamma secretion by human natural killer lymphoma NK-92 cells. The ED50 for this effect is 0.2-2 ng/mL.
• Molecular Mass: The recombinant heterodimer of human IL12A&IL12B comprises 503(197+306) amino acids and has a calculated molecular mass of 57.2(22.5+34.7) KDa. The apparent molecular mass of human IL12 heterodimer is approximately 36 & 42.4 kDa respectively in SDS-PAGE under reducing conditions.
• Protein Length: Met1-Ser219 & Met1-Ser328
• Endotoxin: < 1.0 EU per μg protein as determined by the LAL method.
• Purity: > 95 % as determined by SDS-PAGE
• Storage: Samples are stable for up to twelve months from date of receipt at -20°C to -80°C
  Store it under sterile conditions at -20°C to -80°C. 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 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
