Description

General description

Recombinant, human interleukin-12 expressed in S. frugiperda insect cells. Pleiotropic cytokine that is produced by monocytes/macrophages, B cells, and connective tissue-type mast cells. Also known as natural killer cell stimulatory factor and cytotoxic lymphocyte maturation factor. A potent inducer of IFN-γ production and T cell differentiation and function.

Biochem/physiol Actions

ED₅₀ = 50-200 pg/ml as measured by its ability to stimulate the proliferation of PHA-activated human lymphoblasts

Physical form

Lyophilized from sterile-filtered PBS, 50 µg BSA/µg IL-12.

Preparation Note

Following reconstitution, aliquot and freeze (-70°C) for long term storage or refrigerate (4°C) for short term storage. Stock solutions are stable for up to 1 month at 4°C. Avoid freeze/thaw cycles of solutions.

Reconstitute to a concentration ≥1 µg/ml with sterile PBS containing at least 0.1% HSA or BSA.
