N-(Propargyl-PEG2)-N-bis(PEG3-t-butyl ester) is a 3-arm PEG reagent with a propargyl groups and two t-butyl ester groups. The propargyl group can react with azides via copper catalyzed Click Chemistry reaction to yield a stable triazole linkage. The t-butyl ester groups can be deprotected under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Description
Q-PAGE™ TGN (Tris-Glycine Novel) Precast Gels are ready-to-use acrylamide gels for SDS-PAGE running in Tris-Glycine buffer system. With unique formula, Q-PAGE™ TGN Precast Gels perform enhanced speed, better separation, and longer shelf life as compared with conventional Laemmli Tris-HCl gels. The protein migration patterns in Q-PAGE™ TGN series, however, are similar with typical Laemmli Tris-HCl gels, and thus Q-PAGE™ TGN Precast Gels are compatible to traditional SDS-PAGE and subsequent analyses.
Q-PAGE™ TGN Precast Gels are available in gradient (4 to 15%) and fixed (10%) 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 (QP4XXX) Gels are suitable for Bio-Rad® and other systems. Q-PAGE™ Midi (QP5XXX) Gels are suitable for Invitrogen® XCell SureLock® Mini-Cell, Invitrogen® Mini Gel Tank, Hoefer SE260, and other systems.
Key Features
Storage and stability
Store Q-PAGE™ Precast Gels at 4°C for periods up to 12 months.
Do not freeze Q-PAGE™ Precast Gels. Remove tape and comb before electrophoresis.
Keep Q-PAGE™ Precast Gels flat during storage.

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.
Screening of Lead in water samples at 5-10 ppb
