We describe a strategy for producing human monoclonal antibodies in mice by introducing large segments of the human heavy and κ light chain loci contained on yeast artificial chromosomes into the mouse germline. Such mice produce a diverse repertoire of human heavy and light chains, and upon immunization with tetanus toxin have been used to derive(More)
A novel, non-CB1 cannabinoid receptor has been defined by the persistence of inhibition of glutamatergic EPSPs by the cannabinoid receptor agonist WIN55,212-2 in mice lacking the cloned CB1 receptor (CB1-/-) (Hajos et al., 2001). This novel receptor was also distinguished from CB1 by its sensitivity to the antagonist SR141716A and its insensitivity to the(More)
1. The previously reported induction of luteal 20alpha-hydroxy steroid dehydrogenase by administration of aminoglutethimide to late-pregnant rats was shown to be unaffected by prior removal of the foetuses. Aminoglutethimide therefore does not act via the foetuses in this context. 2. The ability of injected oestrogen to prevent the above induction was lost(More)
1. The variation of the rate of flux with the ;concentrations of the enzymes in multi-enzyme systems is considered. 2. For linear sequences (when the concentrations of the linking intermediates are relatively low) the reciprocal rate is given by a formula in which each term involves the reciprocal of the concentration of one of the enzymes. 3. Interaction(More)
