The Colilert Test uses proprietary Defined Substrate Technology (DST) to simultaneously detect total coliforms and E. coli. Two nutrient-indicators, ONPG and MUG, are the major sources of carbon in Colilert and can be metabolized by the coliform enzyme β-galactosidase and the E. coli enzyme β-glucuronidase, respectively.

The Colilert-18 test uses a proprietary Defined Substrate Technology (DST) nutrient indicators ONPG and MUG to detect coliforms and E. coli. Coliforms use their β-galactosidase enzyme to metabolize ONPG and change it from colorless to yellow. E. coli use β-glucuronidase to metabolize MUG and create fluorescence.

大肠埃希氏菌 利用 β-葡萄糖醛酸苷酶分解 MUG，产物有荧光。 由于大多数非大肠菌群没有这些酶，他们就无法生长，也就不能干扰实验结果。 仅有的几种含有这些酶的非大肠菌群的生长，也被科立得检测专有的配方基质有选择性地抑制住了。 这种方法与传统的培养基法不同。 传统的培养基法为目标生物体和非目标生物体都提供了一个营养丰富的环境，促进他们的生长。 当非目标生物体繁殖，模仿目标生物体时，也就有了假阳性的出现。 在传统培养基中，非目标生物体的生长 …

IDEXX 质量控制实验室是一家经 ISO 17025:2005 认可的实验室。 Colilert-18 检测利用专有固定底物技术酶底物法（DST）营养指示剂 ONPG 和 MUG，检测总大肠菌群和大肠埃希氏菌。 总大肠菌群利用他们自有的 β-半乳糖苷酶代谢 ONPG，使颜色由无色变黄。 大肠埃希氏菌利用 β-葡萄糖醛酸苷酶分解 MUG，产物有荧光。 由于大多数非大肠菌群没有这些酶，他们就无法生长，也就不能干扰实验。 仅有的几种含有这些酶的非大肠菌群的生长，也被 Colilert-18 检测专有的配方基 …

Identifies E. coli specifically, eliminating unnecessary public notification due to non-target organisms. Suppresses up to 2 million heterotrophs per 100 mL. Eliminates the subjective interpretation found in traditional methods. Detects a single viable coliform or E. coli per sample. Minimizes evening and weekend work.

The Colilert 250 Test uses proprietary Defined Substrate Technology (DST) to simultaneously detect total coliforms and E. coli. Two nutrient-indicators, ONPG and MUG, are the major sources of carbon in the Colilert 250 Test and can be metabolized by the coliform enzyme β-galactosidase and the E. coli enzyme β -glucuronidase, respectively.

Coli!ert (Minimal Media ONPG-MUG Test; MMO-MUG) is a direct test of water samples and offers the advantage of simultaneous determination of both total coliforms and E. coli within 24 hours, without the need for confirmatory testing. Setup is simple and results are clearly and easily read with the aid of a comparator.

Colilert 利用IDEXX**技术固定底物技术酶底物法 (DST) 同时检测总大肠菌群和大肠杆菌。 Colilert 采用 ONPG 和 MUG 两种营养指示剂，这两种试剂分别可以被大肠菌群的 β-半乳糖苷酶和大肠杆菌的 β-葡糖醛酸酶分解代谢。

Colilert* simultaneously detects total coliforms and E. coli in water. It is based on IDEXX’s patented Defined Substrate Technology* (DST*). When total coliforms metabolize Colilert’s nutrient-indicator, ONPG, the sample turns yellow. When E. coli metabolize Colilert’s nutrient-indicator, MUG, the sample also fluoresces.
