资源简介：
A method is described in which the adenosine- N -glycosidase activity of ribosome-inactivating proteins (RIPs) is measured using as substrate a 2251 bp [3H]DNA obtained by PCR amplification of the 731-2981 region of the pBR322 plasmid. The DNA, labelled in the purine ring of adenine, proved a good substrate for all three RIPs tested (PAP-S, ricin and shiga-like toxin I). The method, which measures directly the [3H]adenine released, is highly specific, extremely rapid and quantitative in a wide range of RIP concentrations.
