Application examples:	Grape juice, wine, beer, fruit juices, soft drinks, tea, dairy products (e.g. cheese), meat, processed meat, vegetable and fruit products, bakery products, paper, pharmaceuticals, cosmetics and other materials (e.g. biological cultures, samples, etc.).
Method recognition:	Methods based on this principle have been accepted by MEBAK, OIV, EU, ISO2963, AOAC and IFU22 (NOTE: If the enzyme oxaloacetate decarboxylase is present in the sample, some of the oxaloacetate product is converted to pyruvate. Therefore, to ensure citric acid is measured quantitatively, D-lactate dehydrogenase (D-LDH) is employed to efficiently convert any pyruvate produced into D-lactate and NAD+).

The Citric Acid test kit is a flexible and simple method for the rapid and reliable measurement and analysis of citric acid (citrate) in foods, beverages and other materials.

Note for Content: The number of manual tests per kit can be doubled if all volumes are halved.  This can be readily accommodated using the MegaQuant^TM  Wave Spectrophotometer (D-MQWAVE).

Name of Product

IL-6 / Interleukin-6 Test

Catalog Number

MQL6 1

Short Info

Test for the semi-quantitative evaluation of human Interleukin-6 (IL-6) in serum, plasma, cell culture supernatant, amnitotic fluid or cerebrospinal fluid.

This product is only available within the EU!

Method/Platform

lateral flow

Range/Assay Sensivity

50 to 10 000 pg/ml

Test Principle

IL-6 binds to a first anti IL-6 antibody conjugated to gold particles. The IL-6 loaded gold particles diffuse through the membrane and overflow the test line.

A second monoclonal antibody, specific for IL-6 is coated on the membrane. The gold particles are bound specifically and become visible as a coloured line. Colour intensity is directly proportional to the concentration of IL-6 in the sample. The conjugated specific antibodies printed as a second line on the membrane captures the rest of gold conjugate.

Overview

• No need to immediately process samples
• Includes pre-loaded beads for effective sample homogenization by bead beating (tubes are fully compatible with commercially available bead beating systems)
• DNA preservation at room temperature over 2 years
• Ship fecal samples at room temperature safely
• Compatible with most DNA isolation methods 

Norgen’s Fecal DNA Collection & Preservation Mini Tubes are designed for the rapid preservation of DNA from fresh fecal specimens. These tubes contain Norgen’s Fecal DNA Preservative in a liquid format. Moreover, each collection tube is preloaded with beads for effective sample homogenization in any commercially available bead beater equipment (e.g. MP Biomedicals’ FastPrep®-24). The user simply collects fecal samples into the tubes and mixes by shaking or vortexing until the feces is mixed well with preservative. The preservative prevents the growth of Gram-negative and Gram-positive bacteria and fungi, and also inactivates viruses allowing the resulting non-infectious samples to be handled and shipped safely. In addition, the preservative eliminates the need to immediately process or freeze samples and allows the samples to be shipped to centralized testing facilities at ambient temperatures. The components of the preservative allow the DNA in the samples to be preserved at room temperature for over 2 years. 

This kit is highly suited to collection and preservation of fecal material from mouse, hamster, chinchilla, rabbit and more for microbiome studies and other applications.

DNA Isolation from Preservative

Fecal samples collected and preserved in Norgen’s Fecal DNA Collection and Preservation Mini Tubes are compatible with most fecal DNA isolation methods. Samples stored in the tubes have been used successfully with all of Norgen Biotek’s stool-based DNA isolation kits (please refer to Related Products table) and reagents.
