Carbendazim is a fungicide used for the treatment and control of fungal diseases. Carbendazim continues to be used, frequently in combination with other fungicides.
This kit is based on ELISA technology, which is fast, easy, accurate and sensitive compared with common instrumental analysis and only needs 1.5 hours in one operation, it can considerably minimize operation error and work intensity.

Method recognition:
Novel method
PullG6 assay for the measurement of pullulanase employs a water soluble defined substrate, namely 4,6-O-benzylidene-4-nitrophenyl-63-α-D-maltotriosyl-maltotriose (BPNPG3G3), coupled with the ancillary enzymes α-glucosidase and β-glucosidase. Upon hydrolysis of the substrate at the 1,6-α-linkage by pullulanase or limit-dextrinase, the released 4-nitrophenyl-β-maltotrioside is immediately hydrolysed to glucose and 4-nitrophenol by the concerted action of the α-glucosidase and β-glucosidase enzymes in the reagent mixture. The reaction is terminated and phenolate ions are developed by addition of dilute alkali. The absorbance is read at 400 nm and the value obtained correlates directly with pullulanase activity.
Collect from nasal, buccal, saliva, fecal, skin, surfaces, and more
Completely stabilize microbiota profiles from the point-of-collection
Minimize bias in data analysis: NGS (Metagenomics/Microbiome), PCR and microarrays
No need to immediately process samples: ship and store at ambient temperatures
DNA preservation at room temperature over 2 years
Renders sample non-infectious for safe and easy shipping
Compatible with DNA isolation kits and protocols: Optimized isolation procedure using Norgen’s Microbiome DNA Isolation Kit
Norgen’s Swab Collection and DNA Preservation System is designed for collection, ambient storage and transport of DNA from samples collected using a swab, including nasal, buccal, saliva, fecal, skin, surfaces, etc. The Swab Collection and DNA Preservation System contains Norgen’s Swab Preservative in a liquid format. The user simply collects the specimen using the provided swab, and then transfers the swab into the Swab Preservative. The Swab 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 Swab 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 Swab Preservative allow DNA samples to be stored at room temperature for over 2 years.
DNA Isolation from Preservative
Swab samples collected and preserved using Norgen’s Swab Collection and DNA Preservation System are compatible with most DNA isolation methods. Samples stored in the tubes have been used successfully with most of Norgen Biotek’s DNA isolation kits and reagents. An optimized isolation procedure is available as part of Norgen’s Microbiome DNA Isolation Kit (Cat. 64100).
When stored at room temperature, unused Norgen Swab Preservative Tubes are stable through to the collect-before date without any reduction in performance. Please see the device insert or tube label for collect-before date.
