cell line An immortalised cell line is a population of cells from a multicellular organism that would normally not proliferate indefinitely but, due to mutation, have evaded normal cellular senescence and instead can keep undergoing division. The cells ...

BALB/c BALB/c is an albino, laboratory-bred strain of the house mouse from which a number of common substrains are derived. Now over 200 generations from New York in 1920, BALB/c mice are distributed globally, and are among the most widely used inbred ...

IgG1 Immunoglobulin G (IgG) is a type of antibody. Representing approximately 75% of serum antibodies in humans, IgG is the most common type of antibody found in blood circulation. IgG molecules are created and released by plasma B cells. Each IgG ant ...

secreting MOPC21 tumor. From this tumor, the P3K cells were isolated and developed into two cell lines, 289-16 and P3-X63. The 289-16 cell line secreted only light chain and no heavy chain and was renamed NSI/1. Clones from that cell line were isolated and a nonsecreting cell line was identified and was named NS0/1.

Uses in biotechnology

As myeloma cells, NSo cells are naturally antibody-producing suspension cells with a lymphoblast morphology. Gene amplification is typically performed using GS-transfected NS0 cells to select for producing cell lines. The GS-NS0 is a heterologous mammalian expression system that allows for the rapid expression of recombinant proteins. Several therapeutic antibody products are produced using the NS0 cell line including
