Definition of hybridoma : a hybrid cell produced by the fusion of an antibody-producing lymphocyte with a tumor cell and used to culture continuously a specific monoclonal antibody
Monoclonal antibody
Monoclonal antibodies are antibodies that are made by identical immune cells that are all clones of a unique parent cell. Monoclonal antibodies can have monovalent affinity, in that they bind to the same epitope. In contrast, polyclonal antibodies bind to multiple epitopes and are usually made b…

Who coined the term hybridoma?
They shared the Nobel Prize of 1984 for Medicine and Physiology with Niels Kaj Jerne, who made other contributions to immunology. The term hybridoma was coined by Leonard Herzenberg during his sabbatical in César Milstein 's laboratory in 1976–1977.
What is a B cell hybridoma?
[hi″brĭ-do´mah] a somatic cell hybrid formed by fusion of normal lymphocytes and tumor (lymphoma) cells. B cell hybridomas are the most useful source of monoclonal antibodies; the hybridoma cells are able to produce antibody like the normal parent and to proliferate indefinitely in culture like the parent tumor cells.
What is a hybridoma (clone)?
A cell line (CLONE) formed by the fusion of two or more different types of cells, such as a B LYMPHOCYTE and a lymphoid tumour cell (myeloma). Malignant tumours can be immortal so a hybridoma, suitably nourished, can continue permanently exercising the function of the B lymphocyte to produce specific antibodies (MONOCLONAL ANTIBODIES).
What do you mean by hybridoma?
Hybridoma is a culture of hybrid cells that results from the fusion of B cells and myeloma cells. Hybridoma technology produces hybridomas. This technology was developed to produce mAbs. Hybridomas possess two important properties of B cells, production of antibodies, and immortalization of myeloma cells.
What is hybridoma in animal cell culture?
A hybridoma is a cell line arising from one hybrid cell that is capable of secreting a monoclonal antibody specific to one epitope of your antigen permanently in culture.
Why do we use hybridoma?
Hybridoma generation process takes advantage of a host animal's natural ability to generate functional, highly specific and high-affinity mAbs [19]. To date, several mAbs are developed using this technology and are presently used for diagnosis, prevention, and treatment of different diseases Table 1, Table 2, Table 3 .
What is the function of hybridoma cells?
The resulting hybrid cells, called hybridomas, combine the longevity of the myeloma cell with the ability to produce a specific antibody and so are able to produce potentially unlimited amounts of the desired antibody.

What is a hybridoma quizlet?
Hybridomas are cloned, laboratory-made cells obtained by the fusion of antibody-producing spleen cells and a myeloma cell. The hybridoma has monoclonal antibody-producing ability and the "immortality" of myeloma cell.
Why is it called hybridoma?
Hybridoma technology is one of the most common methods used to produce monoclonal antibodies. In this process, antibody-producing B lymphocytes are isolated from mice after immunizing the mice with specific antigen and are fused with immortal myeloma cell lines to form hybrid cells, called hybridoma cell lines.
Who developed hybridoma?
On August 7, 1975, César Milstein and Georges Köhler published their seminal paper on the production of monoclonal antibodies in continuous cell culture. Nine years later, they shared the Nobel Prize in Physiology or Medicine with the Danish scientist Niels K.
What is a hybridoma GCSE?
The spleen cells are fused with human cancerous white blood cells called myeloma cells to form hybridoma cells which divide indefinitely. These hybridoma cells divide and produce millions of monoclonal antibodies specific to the original antigen.
Can hybridoma cells divide?
Formation of monoclonal antibodies The spleen cells are fused with human cancerous white blood cells called myeloma cells to form hybridoma cells which divide indefinitely. These hybridoma cells divide and produce millions of monoclonal antibodies specific to the original antigen.

Why hybridoma technology is important in immunology?
Hybridoma technology is a well-established method to produce monoclonal antibodies (mAbs) specific to antigens of interest. Hybridoma cell lines are formed via fusion between a short-lived antibody-producing B cell and an immortal myeloma cell.
What is hybridoma culture?
Hybridoma is a culture of hybrid cells that results from the fusion of B cells and myeloma cells. Hybridoma technology produces hybridomas. This technology was developed to produce mAbs. Hybridomas possess two important properties of B cells, production of antibodies, and immortalization of myeloma cells.
When was Hybridoma invented?
However, the term “hybridoma” was suggested by Leonard Herzenberg in 1976/1977 ( Milstein, 1999 ). Two important inventions include immortalization of the cells and the development of selection techniques for target cells. Naturally, when an antigen attacks the body (both animal and human), the antigen is phagocytosed by antigen presenting cells.
What antibodies are produced by hybridoma cells?
Hybridoma cells resulting from the fusion of B lymphocytes and myeloma cells produce specific monoclonal antibodies. As more monoclonal antibodies are being used in clinical applications, e.g. Muromonab-CD3 (OK3) to prevent acute rejection of organs (Shapiro et al., 2003), Rituximab™ to treat B-cell lymphoma, etc. (Coiffier et al., 2002, Raderer et al., 2003), a logical extension would be to encapsulate hybridoma cells to deliver monoclonal antibodies in vivo. Hence, anti-VE (vascular endothelium)-cadherin secreting 1B5 hybridoma cells were entrapped into alginate–agarose capsules ( Orive et al., 2001). The antibody was detectable in the medium during the 9 days of culture. The secreted antibody was able to inhibit microtube formation in an in vitro angiogenesis Matrigel assay. However, encapsulated hybridoma cells generated large aggregates in some beads, leading to breakdown of the microcapsules and release of the cells at day 15 (Orive et al., 2003). Hence, uncontrolled proliferation is a serious problem that would limit the use of hybridoma cells in microencapsulation.
What is a hybrid cell?
Hybridomas are hybrid cells produced by the fusion of an antibody-producing lymphocyte with a tumor cell and used to culture continuously a specific monoclonal antibody. From: Encyclopedia of Toxicology (Third Edition), 2014. Download as PDF.
