Our SNPsig® kits use our own proprietary genotyping method to enable the identification of SARS-CoV-2 variants of concern. These products can be used on any real-time PCR machine using familiar protocols, whilst resulting in exceptional genotyping data.
Positive control templates for wild-type and variants are supplied in every kit to make data interpretation simple.
Our SNPsig® technology provides an alternative to sequencing as well as S gene target failure (SGTF) that enables scientists to analyse and monitor these specific genomic mutations. Our kits can provide a pivotal role in screening for SARS-CoV-2 variants for the purpose of genomic surveillance and studies.

Introduction
The HiPure Plant RNA Midi Kit provides fast purification of high-quality RNA from plants, cell, tissues, and yeast using silica-membrane spin columns with a binding capacity of 1mg RNA. There is no need for phenol / chloroform extractions and time-consuming steps such as CsCl gradient ultracentrifugation or precipitation with isopropanol or LiCl. RNA purified using the RaPure Total RNA Purification System can be used for applications such as RT-PCR, Northern blotting, poly A+ RNA (mRNA) purification, nuclease protection, and in vitro translation.

Principle
The Kit isolates total RNA from up to 1g plant tissue. A short workflow enables RNA isolation with genomic DNA removal in less than 40 min. Samples are first lysed and homogenized. The lysate is passed through a DNA Mini column, ethanol is added to the flow-through, and the sample is applied to a RNA column. RNA binds to the membrane and contaminants are washed away. High-quality RNA is eluted in as little as 400µl water using the Kit.
Advantages
Efficient removal of DNA – unique genomic DNA removal column without DNase treatment
High quality – high purity total RNA can be directly used in various sensitive downstream applications
Fast – medium isolation of several samples can be completed in 40 minutes
Safe – no phenol chloroform extraction required
Sensitive – RNA can be recovered at the level of PG
Broad spectrum – various types of plant samples can be processed by diversity of operating procedures

Storage and Stability
The Kit can be stored dry at room temperature (15-25°C) and are stable for at least 18 months under these conditions. Make sure that all buffers are at room temperature when used. During shipment, crystals or precipitation may form in the Buffer RLC/PRC1. Dissolve by warming buffer to 37°C.
Purchase Guide
1. When dealing with woody or uncommon samples, R4150 is recommended first. R4150 contains two polysaccharide/polyphenol lysis buffer, which is the most universal product.
2. R4151 is recommended for handling common economic crop samples for the first time. Strong lysis solution can be used to process easy-extraction samples. The amount of corn or rice leaves samples can reach up to 300mg.
3. R4165 adopts CTAB/chloroform method, which can also handle a large number of difficult-to-extraction plants, but requires contact with chloroform substitutes, which is less safe than other kits. This kit uses DNase Ⅰ to remove DNA, which is also a good choice for extracting polysaccharide/polyphenol-rich plant samples.
4. R4014 is recommended for fruit/starch plant samples, which uses improved trizol pre-treatment, single column operation and is more economical.

For the determination of Escherichia coli in drinking water and its source water by multiple tube fermentation method.
Principle and Interpretation
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 faecalStreptococci.
