Immunotherapy developed in the 1970s following the discovery of the structure of antibodies and the development of hybridoma technology, which provided the first reliable source of monoclonal antibodies.

Field has conducted research in transplantation immunology, immunologic tolerance and CD4 + CD25 + regulatory cells and has a patent pending for : CD4 + CD25 + Inhibitory Hybridoma Clones.

Hybridomas are immortal ( immune to cellular senescence ), HGPRT + cells that result from fusion of mortal, HGPRT + plasma cells and immortal, HGPRT " myeloma cells.
34.
Hybridoma cells can also be isolated using the same principle as described with respect to another gene the HGPRT, which synthesizes IMP necessary for GMP nucleotide synthesis in the salvage pathway.
35.
By using culture supernatant or a purified immunoglobulin preparation, further analysis of a potential monoclonal antibody producing hybridoma can be made in terms of reactivity, specificity, and cross-reactivity.
36.
The lymphocytes eventually die because they are not " immortal . " Only the hybridomas that have " immortality " from their cell line ancestor and thymidine kinase from the plasma cell survive.
37.
Therefore, as a cell line ( e . g ., hybridoma ) expands and expresses a target protein, that protein remains within the EC space and is not flushed out.
38.
Properly supplemented with serum or an adequate serum replacement, RPMI 1640 allows the cultivation of many cell types, especially human T / B-lymphocytes, bone marrow cells and hybridoma cells.
39.
In 1975, Georges K�hler and C�sar Milstein succeeded in making fusions of myeloma cell lines with B cells to create hybridomas that could produce antibodies, specific to known antigens and that were immortalized.

The DSHB is a National Resource established by the National Institute of Child Health and Human Development ( NICHD ) to bank and distribute at cost hybridomas and cell products to the general scientific community.
