Usages： Determination of coliform and fecal coliform for multiple tube fermentation.
Principle: Tryptone provide carbon and nitrogen sources to meet the needs of bacterial growth; sodium chloride osmotic pressure balance can be maintained; Lactose is a coliform fermentable sugars; potassium dihydrogen phosphate and dipotassium phosphate is a buffer; lauryl sodium can inhibit the growth of non-coliform bacteria.
How to use: 1. Suspend 35.6g of the product, adding 1 L of distilled or deionized water, heated to boiling stirring until completely dissolved, packed in a test tube with a small down tube, 121 ℃ autoclave 15min, leave to cool to room temperature, standby . 2.Sample handling and dilution. 3.Selected three consecutive dilution, each dilution was inoculated three LST broth tubes, each tube was inoculated 1mL. 4. Put the tubes in an incubator 36 ± 1 ℃ cultured for 48 ± 2h. 5. Observe the results. if all LST broth don’t pruduse gas, can be reported as negative for E. coli, if gas production then will have to make further confirmed by experiments.
Quality control: Quality control strains were inoculated and culuture at 36 ± 1 ℃ for 24h ,results are as follows: Bacterial Name Bacterial No. Growth Status Gassing Escherichia coli ATCC25922 good +
Salmonella typhimurium CMCC (B) 50115 good —
Staphylococcus aureus ATCC6538 inhibited —
Storage: Store in a dark, cool and dry place, tighten the cap immediately after use. Storage period of three years.
Reagent technology of protein/enzyme system: freeze-dried powder, freeze-dried microspheres
Document
This kit is based on a rapid nucleic acid amplification technology at room temperature and constant temperature: at room temperature and constant temperature (generally 39ºC~42ºC), with the help of auxiliary proteins and single-strand binding proteins,the recombinase and primers form a complex; Source search and combine the target homology domain, at this time, a D-loop region is formed at the homology position and strand exchange begins;along with the dissociation of the recombinase from the complex,the polymerase also binds to the 3′ end of the primer and begins chain extension.It is suitable for laboratory-level DNA amplification and DNA amplification for other detection purposes.
Plasmid DNA is ready for various downstream applications including restriction digestion, bacterial transformation, sequencing and more
Available in 4 formats: MiniPrep, MiniPrep (Magnetic Bead System), 96-Well MiniPrep (Magnetic Bead System), and MaxiPrep
These kits are designed for the rapid preparation of plasmid DNA from Escherichia coli.
Plasmid MiniPrep Kit
This kit is designed for the rapid preparation of plasmid DNA from small cultures of Escherichia coli using convenient spin columns. The plasmid DNA is preferentially purified from other cellular components such as genomic DNA and RNA. This kit is able to purify plasmids up to 13,000 bp in size, and the typical purification yield is up to 20 μg from 1.5 mL of bacterial culture. Purified DNA is of excellent quality for transformation, restriction enzyme digestion, sequencing and more. Also available in a 96-well format.
Plasmid MiniPrep Kit (Magnetic Bead System and High Throughput Magnetic Bead System)
Norgen’s Plasmid MiniPrep Kit (Magnetic Bead System) is designed for the rapid preparation of plasmid DNA from small batch cultures of Escherichia coli. Norgen’s magnetic beads bind DNA under optimized salt concentrations and release the bound DNA under low salt and slightly alkali conditions. The plasmid DNA is preferentially purified from other cellular components such as genomic DNA and RNA. The purified plasmids are fully digestible with all restriction enzymes tested, and are completely compatible with real-time PCR and NGS.
Norgen’s Plasmid MiniPrep Kit (Magnetic Bead System) is also available in a 96-well (HT) format for high throughput applications. Purification with the 96-well plates can be integrated with a robotic automation system.
Plasmid MaxiPrep Kit
This kit is designed for the rapid spin column preparation of plasmid DNA from up to 100 mL of Escherichia coli cultures. The kit allows for the isolation of plasmid DNA with final endotoxin levels of 0.1 EU/µg of DNA or less. The kit is able to purify plasmids up to 13,000 bp in size, and typical yields from a 100 mL culture for a high copy number plasmid are between 0.4 and 1.0 mg. The purified DNA is fully digestible with all restriction enzymes tested, and is completely compatible with manual or automated sequencing to achieve 95-100% accuracy.
All solutions should be kept tightly sealed and stored at room temperature. This kit is stable for 1 year after the of shipment. The RNase should be stored at -20°C upon arrival. The Resuspension Solution AZ should be stored at 4°C upon addition of RNase enzyme.
