چکیده انگلیسی
Ricin acts to damage cells by producing a site of depurination in 28S ribosomal RNA. This depurination results in ribosome inactivation which inhibits protein synthesis and ultimately leads to cell death. We have developed a multiplexed digital droplet polymerase chain reaction assay that enables the objective measurement of toxin activity through quantitation of depurinated 28S rRNA molecules. This assay demonstrates the first use of digital PCR technology to measure ribotoxin-mediated damage. Depurination events were detected in ricin-treated lung cell cultures as early as 1â¯h, and within 9â¯h of exposure the maximum ribosomal damage of 70% was reached and was sustained for at least 24â¯h post-exposure.
