ActoFactor™ Recombinant Human Interleukin 12-p40 (CHO)

  • Specification
  • Recommended Products
Cat.No.
CSC-CTK0249
Description
Interleukin-12 is a disulfide-linked heterodimeric protein (p70), composed of two subunits, p35 and p40, which are encoded by two different genes. Accumulating data indicate that p40 secretion precedes that of IL-12 expression. In addition to its ability to covalently bind to p35 to form IL-12, p40 can bind to p19 to form IL-23. Recombinant human IL-12 p40 is a 40 kDa protein containing 306 amino acid residues.

40 kDa
Size
CAT# CSC-CTK0249-10 (10 μg); CAT# CSC-CTK0249-50 (50 μg)
Expression System
CHO cells
Purity
Greater than 98% as determined by SDS-PAGE and HPLC analysis.
Activity
N/A
Endotoxin Level
Less than 1 EU/μg.
Formulation
Lyophilized from a sterile-filtered solution with no additives.
Reconstitution
Please centrifuge product before opening vial. The lyophilized protein should be reconstituted with distilled, sterile water to a concentration of 0.1-1.0 mg/ml. For further dilution, carrier protein (0.1% BSA or HSA) should be added to avoid loss of bioactivity.
Storage & Stability
The lyophilized protein, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted protein should be used immediately or stored long-term in undiluted working aliquots at -20°C. For long-term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid repeated freeze-thaw cycles.
