<prompt> True about Hybridoma:Immoalise myeloma cellHybridoma cell produced by fusion of T-cell myelomaCell is of human originAll  <response>: A i.e. Immoalise myeloma cell - Hybridoma is an immoal permanent cellQ produced by cell fusion of B cells previously immunized or injected with antigen and myeloma cells of mouseQ or suitable animal. It produces monospecific monoclonal antibodiesQ which can be humanized used in humans by attaching the complementarity - determined regions , the site that binds antigens onto appropriate sites in human immunoglobulin molecule. Attempts to produce human monoclonal antibodies are underway. - Monoclonal antibodies are produced by hybridoma technology in vitro or by one clone secreting specific type of antibody in multiple myeloma in vivo. It is required in minute only microliter quantities and can be used for blood groupingQ.
