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.

Attogene’s Organophosphate detection kit is in designed specifically to detect Organophosphate in liquid samples.
Organophosphate compounds (OP) account for the largest class of rural and urban poisons in the world that are used to kill pests but can also be toxic to humans. OPs cause toxicity by means of blocking the acetylcholinesterase enzyme (AchE). The AChE-directed OPs react with a serine residue that is located at the catalytic site found within the AChE gorge. The OP targeted enzyme is no longer able to hydrolyze ACh, resulting in the buildup of ACh in the nerve synapse. This effect causes excessive excitation of the nerves, producing uncoordinated movements, tremors, paralysis and death. Both synthetic and natural(Guanitoxin) organophosphates are dangerous to humans — exposure can lead to visual, coordination, muscular, and neurological deficiencies, and in some cases even to death. In turn, exposure to OP is a significant public health concern which would significantly benefit from an improved detection platform.
Attogene’s Organophosphate detection kit is in designed specifically to detect Organophosphate in liquid samples. For solid samples a simple sample preparation method is performed. The ability to detect Organophosphate is performed is simple and sensitive. The reaction uses a chromophore that can be detected by eye. In the presence of Organophosphate, the rate of chromophore production is reduced in a concentration dependent fashion. The higher the concentration of Organophosphate the less color is produced.

Solid Phase Reversible Immobilization magnetic beads are often used for DNA purification because they are simple, fast, and effective. The beads are paramagnetic particles coated with carboxyl groups that reversibly bind to nucleic acid. However, Standard SPRI beads can only purify DNA/RNA fragments that are 100 base pairs or longer. DNA/RNA fragments shorter than 100 base pairs are not effectively recovered by SPRI beads. We have developed Magnetic Beads(microRNA & Oligo Purification) to solve the problem.
With our proprietary beads technology, the beads overcomes the hurdle of the short DNA/RNA recovery problem. The magnetic beads is ideal for microRNA purification, oligo purification, short DNA/RNA purification, and removing impurities and unwanted components such as dNTPs, detergents, salts, proteins, and other contaminants effectively. The magnetic bead reagents are RNase-free and can be used for both DNA and RNA applications.
Our magnetic beads are optimized for microRNA purification, oligo purification, and DNA/RNA purification. The fragments can be as short as 20 bases, such as microRNA, tRNA, dsDNA fragments 20 bp or longer, ssDNA fragments 20 nt or longer, RNA fragments 20 nt or longer, DNA/RNA hybrid fragments 20 bp or longer, and oligos and chimeric oligos 20 nt or longer. Purified short DNA and RNA fragments are ideal for applications requiring high-quality fragments, as the fragments are free of impurities and contaminants.
Comparison of short DNA fragments recovery. BioDynami 20 bp DNA ladder (Cat. # 10002) was used as DNA input. Ampure XP beads, BioDynami beads (DNA & RNA purification) and BioDynami beads (microRNA & Oligo purification) were tested. Only BioDynami beads (microRNA & Oligo purification) successfully recovered DNA fragments between 20-100 bp.
Recovery of DNA and RNA oligos with BioDynami magnetic Beads (microRNA & Oligo Purification). 20 nt of DNA oligos and RNA oligos were used as input. Input and recovered oligos were quantified with BioDynami ssDNA Quantification kit (Cat. # 40043) and BioDynami RNA Quantification kit (Cat. # 40044).
