Propargyl-PEG14-acid is an alkyne reagent with a carboxylic acid. The carboxylic acid can form amide bonds with amines under the activation of EDC or HATU. The alkyne group can react with azides through Click Chemistry reaction to form triazole linkage. The PEG spacer increases the solubility of the molecule in aqueous environment. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

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
Format: 10 tests (5 tests/5 controls)
Run Time: 15 Minutes
Introduction
This Kit is designed to purify genomic DNA and total RNA simultaneously from a single biological sample. Lysate is first passed through a DNA spin column to selectively isolate DNA and then through an RNA column to selectively isolate RNA. Pure DNA and RNA are purified from the entire sample, in contrast to other procedures where either the biological sample or the purified total nucleic acids is divided into two before being processed separately. The kit is compatible with small amounts of a wide range of animal cells and tissues.
Specifications
| Features | Specifications |
| Main Functions | Co-isolation DNA and RNA(not include miRNA) from a single sample (cells, soft tissue, plant sample) |
| Applications | RT-PCR, cDNA synthesis, PCR andsecond-generation sequencing, etc. |
| Purification method | Mini spin column |
| Purification technology | Silica technology |
| Process method | Manual (centrifugation or vacuum) |
| Sample type | Soft tissue samples (viscera, excluding skin andmuscle), cultured cells and common plant tissues |
| Sample amount | Soft Tissue: < 30mg, Cell: <1 x 107, Plant: <100mg |
| Yield | DNA: 1 – 20 μg, RNA: 3 – 100 μg |
The Kits are designed to purify both genomic DNA and total RNA from the same cellor tissue sample. Samples are first lysed and homogenized. The lysate is passed through a DNA Mini column and bind DNA. Ethanol is added to the flow-through and the sample is applied to an RNA column. DNA/RNA binds to the membrane and contaminants are washed away. High-quality RNA is eluted in as little as 30µl water using the Kit. High-quality DNA is eluted in as little as 50µl water using the Kit.
