Development and Evaluation of the Determination of the Polyamines Spermine and Spermidine by Radioimmunoassay. Final Report for the Period 1 October 1982-31 January 1985

摘要

In 1975 Bartos et al described a radio-immunoassay for spermine which lacked specificity. In subsequent years the same group has reported the production of a specific antibody to spermidine and to spermine. The availability of specific antibodies potentially transformed the usefulness of radioimmunoassay from a system useful for semi-quantitative screening to one with a much broader applicability in the area of quantitative assay of polyamines. It was claimed that the assay would quantify as little as 10 picogrammes of spermidine or spermine. Up to 1982 when the present project commenced no other groups had reported using the Bartos assay. The present study was therefore indicated in order to determine whether specific antibodies could be produced in laboratories other than those of the Bartos group and to validate the assay by comparing it with the much more widely used and well established HPLC methods currently available.
