Abstract
We describe a novel method for quantification of atrazine based on detection of P450 mRNA levels in Saccharomyces cerevisiae. The selected oligonucleotide probe exhibited specificity against P450 mRNA and was successfully immobilized on the sensor chip. The mRNA was subsequently quantified by RU change using a SPR system. When the cells were disrupted by boiling, mRNA could be measured without further purification at reduced sensitivity. This simple technique permits the detection of atrazine within 15 min. This rapid and highly sensitive method can be used for the detection of atrazine.
