DBCO-NHCO-PEG5-NHS ester is a PEG linker containing NHS ester that is able to react specifically and efficiently with primary amines such as the side chain of lysine residues or aminosilane-coated surfaces at neutral or slightly basic condition to form a covalent bond. The hydrophilic PEG spacer arm improves water solubility and can also provide a long and flexible connection that minimizes steric hindrance during ligation. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Principle
This product is based on silica Column purification. The sample is lysed and digested with lysate and protease, DNA is released into the lysate. Transfer to an adsorption column. Nucleic acid is adsorbed on the membrane, while protein is not adsorbed and is removed with filtration. After washing proteins and other impurities, nucleic acid was finally eluted with low-salt buffer (10mmTris, pH9.0, 0.5mm EDTA).
Advantages
Fast – several samples can be extracted in 20 minutes (after digestion)
High purity – purified DNA can be directly used in various downstream applications
High recovery – DNA can be recovered at the level of PG
Good repeatability – silica technology can obtain ideal results every time

Storage and Stability
Carrier RNA and Proteinase K should be stored at 2–8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15–25°C) does not affect its performance. The remaining kit components can be stored dry at room temperature (15–25°C) and are stable for at least 18 months under theseconditions.

This fast screening test kit contains 10 tests with everything needed for accurate results of unsafe lead levels in the field.
This is a revolutionary product designed to make Lead testing in water safe, easy, and affordable. This fast screening test kit contains 10 tests with everything needed for accurate results of unsafe lead levels. With reliable results in only 10 minutes, this test kit clearly gives results confirming Lead in water and conforming to the EPA guideline of 15 ppb (µg/L). The kit can test water quality from various sources including faucets, wells (ground water), and home purification systems.
High Blood lead levels (i.e., greater than 700ppb) can cause serious health effects, including seizure, coma, and death. Blood levels as low as 100ppb have been associated with adverse effects on cognitive development, growth, and behavior among children aged 1-5 years.
Sample method:
1. Take a first-draw sample
Immediately after opening a faucet or valve, collect a 250 mL sample. This sample should be from each tap used for consumption.
2. Take a flush sample
If first-draw sample results show elevated lead levels of 5 ppb or higher, collect a flush sample. To do this, ensure water has not been used for between 8 to 18 hours, then collect the sample at 30 seconds.
3. Take sequential samples
If you want to test a lead service line, collect 8 to 10 sequential samples, depending on how far the line is from the tap.
