Propargyl-PEG7-acid

DBCO-PEG2-acid is an analog of DBCO-Acid with PEG linker and a DBCO group. The DBCO groups is commonly used for copper-free Click Chemistry reactions due to its strain promoted high energy. The hydrophilic PEG chain allows for increased water solubility. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Reagent grade, for research purpose.

Description

Nucleic acid testing (NAT) is the method of choice for detection and quantification of a wide range of micro organisms. Primerdesign manufactures and supplies high quality quantitative real-time PCR kits for the detection and simultaneous quantification of numerous significant pathogens . A copy number standard curve is provided for quantification and an the internal extraction template (DNA or RNA), controls for the quality of the nucleic acid extraction and eliminates false negative results.

The kit is designed with the broadest possible detection profile to ensure that all clinically relevant strains and subtypes are detected. Target sequences are selected by working with data from key opinion leaders in the field. Multiple sequence alignments and unprecedented real-time PCR expertise in design and validation ensure the best possible kit.

Details of the target and priming specificity are included in the individual handbooks above.

Packaged, optimised and ready to use. Expect Better Data.

Description

Attogene’s Lead Rapid Lab Lateral Flow Kit can be used for the screening of Lead in water and food samples at greater than or equal to 10 ppb in a laboratory setting.  Unlike the field-based kit, the lab kit is intended for a more technical end user who will be evaluating samples in a laboratory setting.

Lead contamination is a serious worldwide environmental problem. As it is difficult to detoxify by chemical or biological methods, gradual Lead ion accumulation in the nervous and cardiovascular systems of the human body can subsequently cause serious diseases.   Long-term health consequences of drinking Lead-contaminated food and water include brain, heart, kidney, lungs  and immune system problems for adults, and the physical and mental development delays in infants and children.  Attogene’s Lead Lateral Flow test gives results conforming of 10ppb or greater in 5-15 minutes.

This is a revolutionary product designed to make Lead testing in 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).

Sample Collection:

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.

Standards and Regulations and recommendations for Lead

• EPA: Drinking Water: 15ppb
• FDA: Juice: 50ppb
• EPA: Residential Soil: 400 ppm (play areas), 1200 ppm (non-play areas)
• CPSC: Paint: 90ppm
• FDA: Bottled drinking water: 5ppb

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.

Screening of Lead in water samples at 5-10 ppb
Format: 10 tests (5 tests/5 controls)
