TD5 Table Top Low Speed Centrifuge 

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)
Run Time: 15 Minutes

Overview

• Isolate all sizes of circulating and exosomal RNA, including microRNA
• Versatile plasma/serum input ranges
• No phenol extractions
• No carrier RNA
• Bind and elute all RNA irrespective of size or GC content, without bias
• Concentrate circulating RNA and exosomal RNA into a flexible elution volume
• High quality, purified RNA is suitable for a variety of downstream applications, including Small RNA Sequencing. Find out more information on Norgen’s NGS services
• Compatible with Streck Cell-Free RNA BCT® Tubes
• Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix

These kits provide a fast, reliable and convenient method to purify and concentrate high quality, high purity and inhibitor-free cell-free circulating and exosomal RNA using a convenient spin column method. These kits can purify RNA from fresh or frozen serum or plasma samples prepared from blood collected on either EDTA or Citrate. Plasma samples prepared from blood collected on heparin should not be used, as heparin can significantly interfere with many downstream applications such as RT-PCR. The purified plasma/serum RNA is fully compatible with all downstream applications including PCR, qPCR, methylation-sensitive reverse transcription qPCR, reverse transcription PCR, Northern blotting, RNase protection and primer extension, expression array assays, and NGS.

Background

Plasma/Serum cell-free circulating RNA or exosomal RNA has the potential to provide biomarkers for certain cancers and disease states. Exosomes are 40 – 150 nm membrane vesicles, which are secreted by most cell types. Exosomes can be found in saliva, blood, urine, amniotic fluid and malignant ascitic fluids, among other biological fluids. Evidence has been accumulating recently that these vesicles act as cellular messengers, conveying information to distant cells and tissues within the body. These exosomes may play a functional role in mediating adaptive immune responses to infectious agents and tumours, tissue repair, neural communication and transfer of pathogenic proteins. For this reason exosomal RNAs may serve as biomarkers for various diseases including cancer. As the RNA molecules encapsulated within exosomes are protected from degradation by RNAses they can be efficiently recovered from biological fluids, such as plasma or serum.

Plasma/Serum RNA Purification Mini Kit

This kit can purify RNA from fresh or frozen serum or plasma samples prepared from blood collected on either EDTA or Citrate, from volumes ranging from 50 µL to 200 µL. The purified plasma/serum RNA is eluted in a flexible final volume of 10 µL to 25 µL.

Plasma/Serum RNA Purification Midi Kit

This utilizes a two column method, and can purify RNA from fresh or frozen serum or plasma samples prepared from blood collected on either EDTA or Citrate, from volumes ranging from 250 µL to 1.5 mL. The first column will handle the large volume input of bodily fluids that is followed by a concentration on a mini column for a final elution of 50 µL to 100 µL.

Plasma/Serum RNA Purification Maxi Kit

This kit can purify RNA from fresh or frozen serum or plasma samples prepared from blood collected on either EDTA or Citrate, from volumes ranging from 2 mL to 5 mL. The first column will handle the large volume input of bodily fluids that is followed by a concentration on a mini column for a final elution of 50 µL to 100 µL.
