CP0203J Triple Wrapped Irradiated Plate-Tryptic Soy Agar with Lecithin Tween 80

Description

Tyrosinase Inhibitor Screening Kit (Colorimetric) provides a rapid, simple, sensitive, and reliable test suitable for high-throughput screening of tyrosinase inhibitors. Tyrosinase catalyzes the oxidation of tyrosine, producing a chromophore that can be detected at OD = 510 nm. In the presence of kojic Acid, a reversible inhibitor of tyrosinase, the rate of oxidation of the substrate is decreased.

Tyrosinase or polyphenol oxidase is an oxidoreductase that participates in the biosynthesis of melanin, a ubiquitous biological pigment found in hair, eyes, skin, etc. Inhibition of tyrosinase has been a long-time target in the skin health research, cosmetics and agricultural industries because of its role in browning reactions in skin pigmentation and during fruit harvesting and handling.

For rapid, sensitive and accurate screening of potential Tyrosinase inhibitors

Overview

• Removes primer dimers
• Simultaneously clean-up and normalize PCR products 
• Fast (less than 20 minutes), high-throughput and easy processing using centrifugation
• Sufficient elution volume (100 µL) for repeat or future assays 
• Non-magnetic bead purification 

Norgen’s NGS Normalization 96-Well Kit allows for high-throughput NGS library PCR amplicon clean-up and normalization of NGS library PCR product concentration. The clean-up removes all PCR by-products including primers, dimers, enzymes and unincorporated nucleotides during the library prep PCR step. Purification is based on 96-well column chromatography using Norgen’s proprietary resin as the separation matrix. The amount of Norgen’s matrix in each 96 well is optimized to have a limited binding capacity, thus each well can elute an equal concentration of PCR product. The process involves first adding 3 volumes of Buffer SK to the PCR product, and the mixture is then loaded onto the 96-Well Normalization Plate. The bound PCR amplicon is then washed with the provided Wash Solution A in order to remove any remaining impurities, and the purified PCR amplicon is eluted with Elution Buffer B. The purified and normalized library PCR amplicon can then be used in NGS workflows and other sequencing applications.

Description

Okadaic Acid (OA) is a one of the diarrhetic shellfish poisons (DSP) produced by dinoflagellate genera Dinophysis and Prorocentrum. There are several chemically different toxins associated with DSP.

They are lipophilic and polyether compounds and can be divided into three main groups:

1. Acidic toxins
2. Neutral toxins
3. Other toxins 2 Contamination of shellfish with OA has been associated with harmful algae blooms throughout the world.

In humans, DSP causes dose-dependent symptoms of diarrhea, nausea, and vomiting. The action levels established by the FDA for OA is 200ppb. The EU has established a level of 160 ppb of OA or its equivalent.

The Attogene Okadaic acid ELISA kit enables international and government regulatory agencies, food manufacturers and processors, as well as quality assurance organizations to detect OA in food, feed, fish, and environmental samples of concern.

Okadaic acid is the causative agent of Diarrhetic Shellfish Poisoning (DSP).
