The lymphocytes are fused with cells from a non-antibody producing and myeloma (continuously growing tumor cell line), as the hybrids continue to secrete antibodies while gaining the immortality of the parent tumor cells. (savedelicious.com)

Selection of the hybridomas: Hybridoma selection in HAT (Hypoxanthine, Aminopterine,Thymidine ) medium is followed by screening of the antibody specificity. (savedelicious.com)
Screening of the antibodies: Hybridomas need to screened for desired antibody specificity. (savedelicious.com)

The four known IgG subclasses are involved in antibody-dependent cellular cytotoxicity.Antibodies are a key component of the adaptive immune response, playing a central role in both in the recognition of foreign antigens and the stimulation of an immune response to them. (wikipedia.org)
Transmembrane or otherwise tumor-associated polypeptides specifically expressed on the surface of cancer cells as compared to normal, non-cancerous cell(s) have been identified as cellular targets for cancer diagnosis and therapy with antibodies. (justia.com)
Receptors for the Fc region of IgG (Fc gamma Rs) are members of the Ig superfamily that function in the activation or inhibition of immune responses such as degranulation, phagocytosis, ADCC (antibody-dependent cellular toxicity), cytokine release, and B cell proliferation (1‑3). (novusbio.com)

citation needed] 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. (wikipedia.org)
citation needed] Initially, murine antibodies were obtained by hybridoma technology, for which Jerne, Köhler and Milstein received a Nobel prize. (wikipedia.org)
This monoclonal antibody is produced by using a technology called "Hybridoma technology" which was discovered by George Kohler of West Germany and Cesal Milstein of Argentina in 1975 (Global-research-online.net, 2018). (savedelicious.com)

Monoclonal antibody therapy may prove to be beneficial for cancer, autoimmune diseases, and neurological disorders that result in the degeneration of body cells, such as Alzheimer's disease. (wikipedia.org)
Neonatal lupus is a passively acquired autoimmune disease that occurs in offspring of mothers with anti-SSA/Ro and/or anti-SSB/La antibodies. (heraldopenaccess.us)

Acts as an activator of Notch pathway by mediating cleavage of Notch, generating the membrane-associated intermediate fragment called Notch extracellular truncation (NEXT) (PubMed:24226769). (qedbio.com)
It contains a large 762 amino acid (aa) extracellular domain (ECD) (aa 35-795) plus a 274 aa cytoplasmic region. (novusbio.com)

Monoclonal antibodies can target tumor cells or abnormal cells in the body that are recognized as body cells, but are debilitating to one's health. (wikipedia.org)
The use of antibody-drug conjugates (ADC), i.e. immunoconjugates, for the local delivery of cytotoxic or cytostatic agents, i.e. drugs to kill or inhibit tumor cells in the treatment of cancer (Lambert, J. (2005) Curr. (justia.com)

Ble atheroprotective effects, an anti-LDL(-) single-chain variable fragment (scFv) was expressed inside the methylotrophic yeast Pichia pastoris and its activity was evaluated in vitro against macrophages and in experimental atherosclerosis in Ldlr-/- mice. (m-entrepreneurship.com)

To obtain scFv fragments, mRNA is first isolated from hybridoma (or spleen cells and B lymphocytes) followed by reverse transcribed into cDNA to serve as a template for the polymerase chain reaction (PCR) amplification of the antibody genes. (biologicscorp.com)

Immunoaffinity chromatography utilizes the high specificity of antigen-antibody interactions to achieve a separation. (chempedia.info)

So monoclonal antibodies are 'hybrid' cells that are created by the fusion of two cells, which is a myeloma cell with genetic potential of multiplication characters, and another cell that has a gene that codes for the targeted antibody (Kumar et al. (savedelicious.com)

Antibodies and antigens fit tightly together because their shape and other surface properties (eg, charge) are complementary. (msdmanuals.com)
