Tk. Lim et al., Detection of atrazine based on the SPR determination of P450 mRNA levels in Saccharomyces cerevisiae, ANALYT CHEM, 72(13), 2000, pp. 2856-2860
We describe a novel method for quantification of atrazine based on detectio
n of P450 mRNA levels in Saccharomyces cerevisiae. The selected oligonucleo
tide probe exhibited specificity against P450 mRNA and was successfully imm
obilized on the sensor chip. The mRNA was subsequently quantified by RU cha
nge using a SPR system. When the cells were disrupted by boiling, mRNA coul
d be measured without further purification at reduced sensitivity. This sim
ple technique permits the detection of atrazine within 15 min. This rapid a
nd highly sensitive method can be used for the detection of atrazine.
