Enhancement of growth hormone activity in vivo by monoclonal antibodies: potential for autoimmunization

Monoclonal antibodies against bovine growth hormone.

A number of mouse x mouse hybridomas producing monoclonal antibodies (MAbs) against bovine growth hormone (bGH) were prepared by fusion of spleen cells from bGH-primed mice (Balb/c) with non-secretory mouse myeloma cells (PAIOP3) and characterized. MAbs obtained from three fusion experiments belonged to IgM, IgG1 and IgG2b class/subclass of antibodies. Cross-reaction studies indicated that gene...

An ln vivo Assay for Biological Activity of Synthesized Recombinant Human Growth Hormone

Effects of complexation with in vivo enhancing monoclonal antibodies on activity of growth hormone in two responsive cell culture systems.

We describe the properties of three monoclonal antibodies (MAbs) to ovine GH, two of which have previously been shown to enhance, in vivo, the biological activity of bovine and ovine growth hormone. We have examined the effects of these MAbs on GH activity in two appropriate GH-responsive cell culture systems, investigating both acute signalling effects (Janus-activated kinase (Jak)-2 tyrosine ...

Monoclonal Antibodies

SUMMARY Monoclonal Antibodies are identical antibodies and Can be generated in ultimated amounts by countinuos cultures of single antibody- secreting cells. These cell lines are produced by cell fusion of normal lymphocytes to cells of a myeloma tumor cell line, which confers on the antibody producing hybrid cell, immortality and the ability grow as atumor in animals. monoclonal antibodies c...
