A robust, simple solution for sealing & disposing of all 96 extraction tubes
For the determination of Escherichia coli in drinking water and its source water by multiple tube fermentation method.
MUG permits the rapid detection of Escherichia coli when the medium is observed for fluorescence using a UV light. MUG is hydrolyzed by the enzyme β-glucuronidase which is produced by E. coli to yield a fluorescent end product 4- methylumbelliferone. Trypticase provides the essential nutrients. Lactose is the fermentable carbohydrate. Sodium chloride maintains the osmotic equilibrium. The medium has a strong buffering system to control the pH in the presence of fermentative action. The bile salts inhibit gram-positive bacteria especially the Bacillus species and faecal Streptococci.

Weigh 37g of dry powder of this product, add 1L of distilled water or deionized water, stir, heat and boil until
completely dissolved, sterilize at 115℃ for 20min, cool to room temperature and set aside.
The following quality control strains were inoculated and cultured at 44.5℃±0.5℃ for 24h. The results are as follows:
| Quality control strains | Growth |
| Escherichia coli ATCC25922 | Blue-white fluorescence is produced under 366nm UV light |
| Salmonella typhimurium ATCC14028 | No fluorescence under 366nm UV light |
| Enterococcus faecalis ATCC29212 | Clear, no fluorescence |
2-30℃，Keep container tightly closed, avoid direct sunlight.
Use before expiry date on the label.
1. When weighing the dehydrated medium, please wear masks to avoid causing respiratory system discomfort
2. Keep container tightly closed after using to prevent clumping.
Microbiological contamination was disposed by autoclaving at 121°C for 30 minutes.

PAX-8 is a member of the paired box (PAX) family of transcription factors, which are key regulators in early development. This protein plays a role in development of thyroid follicular cells and the expression of thyroid-specific genes, with mutations in the PAX-8 gene linked to thyroid follicular carcinomas, atypical thyroid adenomas, and thyroid dysgenesis. The PAX-8 protein is expressed in simple ovarian inclusion cysts and non-ciliated mucosal cells of the fallopian tubes, but is absent from normal ovarian surface epithelial cells. PAX-8 is also not expressed in normal lung or lung carcinomas. Reports have associated PAX-8 expression with renal carcinoma, nephroblastoma, and seminoma, and have indicated PAX-8 as a useful marker for renal epithelial tumors, ovarian cancer, and for differential diagnoses in lung and neck tumors. Anti-PAX-8 can be useful in determining the primary site of invasive micropapillary carcinomas of ovary from bladder, lung, and breast, when used in adjunct with a panel of organ-specific markers such as uroplakin, mammaglobin, and TTF-1.
