Formulation

Lyophilized from sterile PBS, pH 7.4.Normally 5%-8% trehalose and mannitol   are added as protectants before lyophilization.

Reconstitution

Dissolved in sterile water, it is recommended to add 0.1% HSA or BSA   for long-term preservation.

STORAGE

Stability and Storage

12 months from date of receipt at -20°C to -70°C. After reconstitution,   it is stable at 4°C for 1 week or -20°C for almost 6 months (with carrier   protein). It is recommended to freeze aliquots at -20°C or -80°C for extended   storage.

BACKGROUND

Interleukin-12 (IL-12), is a cytokine that is secreted by activated   phagocytes and dendritic cells and that induces interferon-γproduction by   natural-killer and T lymphocytes. IL-12 (referred to as 'p70') is a 70 kDa   heterodimer composed of a 35 kDa subunit (IL-12A p35) and a 40 kDa subunit   (IL-12B p40). IL12 act as a growth factor for activated T and NK cells,   enhance the lytic activity of NK/lymphokine-activated Killer cells, and   stimulate the production of IFN-gamma by resting PBMC. IL-12 also has   anti-angiogenic activity, which means it can block the formation of new blood   vessels. IL-12 has been shown to play a critical role in the pathogenesis of   a variety of immune-related diseases.
