Description
Q-PAGE™ Bis-Tris Precast Gel is a high-performance and easy to use precast polyacrylamide gel for electrophoresis in Bis-Tris buffer system (MOPS or MES). The optimized gel formula allows Q-PAGE™ Bis-Tris Precast Gel to show improved resolution, accurate results, and an extended shelf-life over conventional Laemmli Tris-HCl gels.
Q-PAGE™ Bis-Tris Precast Gels are available in gradient (4 to 12%) and fixed (8% and 12%) concentrations of polyacrylamide in 12-and 15-well formats. Two available cassette sizes, Mini (10 x 8.3 cm) and Midi (10 x 10 cm), are compatible with most popular protein electrophoresis systems. Q-PAGE™ Mini (QP2XXX) Gels are suitable for Bio-Rad® and other systems. Q-PAGE™ Midi (QP3XXX) Gels are suitable for Invitrogen® XCell SureLock® Mini-Cell, Invitrogen® Mini Gel Tank, Hoefer SE260, and other systems.

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
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.

The Acetic Acid GK format test kit is for use with auto-analysers and is suitable for the specific measurement and analysis of acetic acid (acetate) especially in wines, fruit juices, beverages and food products.
As part of Megazyme’s overall commitment to providing the highest quality products, we have developed this acetic acid kit that provides a specific and rapid assay for use with auto-analysers. The kit assay is based on the conversion of NAD+ to NADH and therefore provides a positive reaction (increase in absorbance) which offers a more robust assay.
The reagents, as supplied, are stable for a minimum of 2 years and the prepared reagents are stable for a minimum of 1 week (on-board stability). In addition, the prepared reagents can be stored frozen for longer term stability (see K-ACETGK Booklet for more details).
