HCM196 Yeast Extract Peptone Dextrose Agar

N-(Propargyl-PEG2)-PEG3-N-Boc is a branched PEG linker with an alkyne group and a t-butyl ester. The alkyne group reacts with azide-bearing compound in coppper catalyzed azide-alkyne Click Chemistry reaction. The Boc group can be deprotected under acidic conditions. The amino group is reactive with carboxylic acids, activated NHS esters, and carbonyls. Reagent grade, for research purpose.

Propargyl-PEG5-amine is a propargyl linker that is commonly used as a Click Chemistry reagent for copper-catalyzed reactions with azides. The amine moiety reacts with carboxylic acids, activated NHS esters and other carbonyl compounds. The PEG spacer helps improve the water solubility of the molecule in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

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
