PEG3-bis(Amino-Tri-(Propargyl-PEG8-ethoxymethyl)-methane) is large molecule with two sets of three terminal alkynes joined together by a short PEG linker. The alkynes are most frequently used in copper click chemistry with azides to form stable triazoles with the target compound. The PEG linkers as well as numerous amide bonds provide high aqueous solubility to this compound, which may alter DMPK of this compound.

Introduction
Usages:
For the rapid detection and enumeration of Escherichia coli.
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 coli β- glucuronidase enzyme specific reaction, hydrolysis of the substrate, the release of the color groups produce green colonies on the light yellow plate.
Formulation (per liter):
Peptone :15.0g
Yeast extract powder: 3.0g
Sodium chloride: 5.0g
Sodium lauryl sulfate:0.1g
Agar: 12.0g
Chromogenic substrate 6.5g
Final pH 7.0 ± 0.2
How to use:
1. Weigh 41.6g of the product, adding 1.0L distilled or deionized water, heated to boiling stirring until completely dissolved, dispensing into flask, 115 autoclaved for 10minutes.
2. Take 25.0g or 25.0ml of sample with sterile procedures , added to the flask containing 225.0mL of sterile phosphate buffered saline (or saline) , shaken thoroughly homogenized with a homogenizer or a 1:10 dilution of 1min solution, diluted 1:10 and then continue to select the appropriate serial dilutions of three, the two plates inoculated with each dilution, poured dissolved by heating and cooled to about 45 medium.
3, observe the results.
Quality Control
This product appears light yellow after the pouring on plate, these strains were inoculated after 36 ± 1 18 ~ 24h culture growth in the following table.

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 to remove salts, and finally DNA was eluted by Elution Buffer.
Advantages
High purity – OD 260 / 280 : 1.7- 1.9, OD 260 / 230 : 1.5 – 2.0
Economy – less than 50% of the price of Qiagen and other imported products
High yield – most optimal process, ensuring the recovery up to 90%
Strong processing ability – samples including animal blood, cultured cells, animal tissues, etc.
Proteinase K, RNase A, 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 at room temperature (15-25°C) and are stable for at least 18 months under these conditions.

The ExcelTaq™ 2X Q-PCR Master Mix (TaqMan, ROX) is a ready-to-use reagent with all the essential components for quantitative real-time PCR (qPCR) except primers, TaqMan probes and templates. The master mix includes a 5’ to 3’ exonuclease activity to cleave TaqMan probes that hybridize to target sequences, releasing fluorophore during probe displacement. With TaqMan probes, the master mix features high specificity and high sensitivity. The ExcelTaq™ 2X Q-PCR Master Mix (TaqMan, ROX) contains hot-start Taq polymerase in an optimized buffer that allows for sensitive and precise amplification, real-time tracking of the amplification process, and simultaneous quantification for targeted DNA molecules. The master mix includes ROX reference dye for the normalization of each qPCR assay. The ExcelTaq™ 2X Q-PCR Master Mix (TaqMan, ROX) is ready-to-use and greatly reduces pipetting errors, while largely improving the reproducibility of the process.
Features
