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 antibody reacts with human epsilon heavy chain. |
Derivation |
Lymph node cells were fused with S194/5.XXO.BU.1 myeloma cells. |
Genes Expressed |
immunoglobulin; monoclonal antibody; against human epsilon immunoglobulin heavy chain (IgE) |
Cellular Products |
immunoglobulin; monoclonal antibody; against human epsilon immunoglobulin heavy chain (IgE) |
Tumorigenic |
Yes |
Effects |
Yes, forms ascites in pristane-primed BALB/c mice (Generally, the first i.p. passage yields mostly adherent tumor cells and little ascites, but serial passage of the ascites cell in additional BALB/c mice will yield large amounts of ascites that may contain up to 20 mg/ml of the antibody. For monoclonal antibody production in ascites, cells should be injected (10 to 20 million cells) intraperitoneally (i.p.) in pristane-primed BALB/c mice.) |
Comments |
Animals were immunized with a human IgE paraprotein (PS). Lymph node cells were fused with S194/5.XXO.BU.1 myeloma cells. The antibody reacts with human epsilon heavy chain. It has a very high affinity (3 X 10 exp-10 m/L) for an epitope located between amino acids 218 and 301 (CH2 domain) of human epsilon. It does not bind to protein A, but functions well in histamine release assays. |
Complete Growth Medium |
The base medium for this cell line is ATCC-formulated RPMI-1640 Medium, Catalog No. 30-2001. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
|
Subculturing |
Medium Renewal: Every 2 to 3 days Cultures can be maintained by addition or replacement of fresh medium. Start cultures at 2 X 10 exp5 cells/ml and maintain between 1 X 10 exp5 and 1 X 10 exp6 cells/ml. |
Cryopreservation |
Freeze medium: complete growth medium, 95%; DMSO, 5% |
