Comments: The hybridoma cell line 20C2 [4H12:20C2.G6.C9} was established by Richard Chizzonite in 1991 and subcloned three times by limiting dilution.
The hybridoma produces an antibody (IgG1) that binds the p75 heterodimer of human IL-12.
The antibody may be used in neutralizing and receptor binding assays; it will immunoprecipitate IL-12.
The antibody can be used as a capture antibody in sandwich EIA to detect the p75 form of human IL-12.
The 20C2 antibody does not bind the p40 or p35 subunits of IL-12.
The 20C2 cell line was formed by the fusion of NSO mouse myeloma cells with splenocytes from a Lewis rat inoculated with partially purified human IL-12 p75. [38686]
Propagation: ATCC complete growth medium: Iscove's Modified Dulbecco's Medium with 4 mM L-glutamine adjusted to contain 1.5 g/L sodium bicarbonate supplemented with 0.1 mM 2-mercaptoethanol, 90%; fetal bovine serum, 10%.

Subculturing: Medium Renewal: Add fresh medium every 2 to 3 days (depending on cell density)
Cultures can be maintained by the addition of fresh medium or replacement of medium. Alternatively, cultures can be established by centrifugation with subsequent resuspension at 1 to 2 X 10 exp5 viable cells/ml.
Maintain cell density between 1 X 10 exp5 and 1 X 10 exp6 viable cells/ml.
Preservation: culture medium 95%; DMSO, 5%
