產品名稱 20C2 [4H12:20C2.G6.C9]
商品貨號 B163639
Organism Rattus norvegicus (B cell); Mus musculus (myeloma), rat (B cell); mouse (myeloma)
Cell Type hybridoma: B lymphocyte
Product Format frozen
Morphology lymphoblast
Culture Properties suspension
Biosafety Level 1

Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country.
Applications
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.
Storage Conditions liquid nitrogen vapor phase
Derivation
The hybridoma cell line 20C2 [4H12:20C2.G6.C9} was established by Richard Chizzonite in 1991 and subcloned three times by limiting dilution.
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.
Genes Expressed
immunoglobulin; monoclonal antibody; against human interleukin 12 (IL-12) p75
Cellular Products
immunoglobulin; monoclonal antibody; against human interleukin 12 (IL-12) p75
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.
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 Cultures can be maintained by addition of fresh Medium. Alternatively, cultures can be established by centrifugation with subsequent resuspension at 1 to 2 x 105 viable cells/mL.  Maintain cultures at a cell concentration between 1 x 105 and 1 x 106 cells/mL. Maintain cell density between 1 x 105 and 1 x 106 viable cells/mL.

Medium Renewal: Add fresh medium every 2 to 3 days (as cell density increases)

Cryopreservation

Complete growth medium described above supplemented with 5% (v/v) DMSO.  Cell culture tested DMSO is available as ATCC Catalog No. 4-X.
