DBCO-PEG2-amine is a PEG linker which contains DBCO and amine moieties. The DBCO group is commonly used in copper-free Click Chemistry reactions. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde), etc. The hydrophilic PEG spacer increases the water solubility of the compound. Reagent grade, for research purpose.

Introduction
Usages:
For the rapid detection and enumeration of coliform bacteria.
Principle:
Peptone and yeast extract powder provides carbon and nitrogen sources and trace elements; sodium chloride maintains osmotic equilibrium; agar as medium coagulant; dodecyl sulfate inhibit Gram-positive bacteria; chromogenic substrate and large intestine flora β- galactosidase-glucosidase specific reaction, hydrolysis of the substrate, the release of the color groups produce green colonies on the light yellow plate.
Formulation (per liter):
Peptone :10g
Yeast extract powder: 3g
sodium chloride:5g
sodium lauryl sulfate:0.1g
Agar :12g
Chromogenic substrate 2.7g
Final pH 7.0 ± 0.2
How to use:
1. Weigh 32.8g of this product, adding 1L of distilled or deionized water , heated to boiling stirring until completely dissolved, dispensing into flask without autoclaving.
2,Take 25g or 25mL of sample with aseptic procedures, added to the flask containing 225mL of sterile phosphate buffered saline (or saline) is shaken thoroughly homogenized with a homogenizer or a 1:10 dilution 1min, then 1:10 dilution continue to select the appropriate serial dilutions of three, two plates each dilution was inoculated.
3, the use of pour method: The medium is cooled in a water bath to about 50 , sterilized petri dish having a diameter 90mm, 1ml samples were inoculated per dish, then poured into about 15ml of the above dissolution medium, and mix to solidify, upside down, 37 for 24 hours.
4, using surface inoculation: cooled to about 50 , shake devoted to the medium in sterile petri dish. Can be stored in the refrigerator for a day or stored at room temperature for several days (dark, 4 ). The sample was streaked method or filter method, 37 for 24 hours.
5, observe the results.
Quality control:
This product appear light yellow after pouring into plate, these strains were inoculated after 36 ± 1 18 ~ 24h culture growth in the following table.
Growth of bacteria were cultured bacteria numbers feature
Escherichia coli ATCC25922 good green colonies
Citrobacter ATCC8090 good green colonies
Salmonella typhimurium CMCC50115 good colorless colonies
Enterococcus faecalis ATCC29212 suppressed —–
Storage: Store at 10-30 , dark, cool and dry place, tighten the cap immediately after use. Storage period of two years.
MagPure Plant DNA Kit supplies a simple and rapid extraction of genomic DNA from different plant pieces and tissues.The kit is based on superparamagnetic particles purification technology, no phenol-chloroform extraction or alcohol precipitation. The whole extraction only takes 60 minutes. This kit can be used on different automatic extraction machines like KingFisher ML, KingFisher Flex and KingFisher Duo.Purified DNA can be used directly for PCR, quantitative PCR, southern blot, hybridization, and transgenosis detection.

Main Functions
Isolation total DNA from 50-100 mg plant, fungal tissue
Applications
PCR, transgene detection, fluorescence quantitative PCR, southern blot, SNP site analysis, etc.
This product is based on the purification method of high binding magnetic particles. The sample is lysed and digested under the action of lysate and Protease. DNA is released into the lysate. After adding magnetic particles and binding solution, DNA will be adsorbed on the surface of magnetic particles, and impurities such as proteins will be removed without adsorption. The adsorbed particles were washed with washing solution to remove proteins and impurities, washed with ethanol toremove salts, and finally DNA was eluted by Elution Buffer.
Advantages
Safe – require no phenol or chloroform extraction
Fast – several samples can be extracted in 60 minutes
High purity – high quality DNA, completely remove inhibitors

Storage and Stability
RNase Solution and MagPure Particles should be stored at 2-8°C upon arrival. However, short-term storage (up to 24 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored dry at room temperature (15-25°C) and are stable for at least 18 months under these conditions.
