Relevance

Cytokine that can 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.

Endotoxin

Less than 1.0 EU/μg as determined by LAL method.

Purity

>95% as determined by SDS-PAGE.

Activity

Yes

Bioactivity

Measured in a cell proliferation assay using PHA-stimulated human T lymphoblasts. The ED50 for this effect is 0.01-0.05 ng/mL. The specific activity of rHuIL-12 is approximately 1.1 x 104 units/μg, which is calibrated against

Form

Lyophilized powder

Buffer

Lyophilized from a 0.2 µm filtered PBS, pH 7.4

Reconstitution

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Function

Cytokine that can 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.

Molecular Weight

57.2 kDa. 75.0 kDa is the observed value of non-reducing gel, and the reducing glue is the size of p40 and p35 subunits, and 57.2 kDa is the theoretical value.

Storage Conditions

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
