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.

Introduction
This kit is suitable for extracting total pathogen nucleic acid from a variety of clinical samples such as blood, serum, plasma, swab soaking solution, fluid accumulation and homogenate solution. This kit is designed to remove host cells background nucleic acid and enrich pathogen nucleic acid (including viral/bacterial/fungal DNA/RNA) from the sample. Purified DNA/RNA is ready for downstream applications such as PCR, virus detection, tNGS and other related experiments.

Principle
This product is based on the purification method of high binding magnetic particles. The sample is lysed and digested under the action of lysate and Protease. After adding magnetic particles and binding solution, DNA/RNA will be adsorbed on the surface of magnetic particles, and impurities such as proteins will be removed without adsorption. The adsorbed particles were washed with washing solution to remove proteins and impurities, washed with ethanol to remove salts, and finally DNA/RNA was eluted by Buffer NFW.

Storage and Stability
Proteinase K, DNase I powder and MagPure Particles N9 should be stored at 2–8°C upon arrival. However, short-term storage (up to 8 weeks) at room temperature (15–25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15–25°C) and are stable for at least 18 months under these conditions.

Solid Phase Reversible Immobilization magnetic beads consist of paramagnetic particles coated with carboxyl groups that reversibly bind DNA. They are used for DNA purification because they are fast, simple and efficient. We have developed our own beads technology that are different from other SPRI beads technologies.
Our Magnetic Beads(DNA & RNA Purification) combines BioDynami’s proprietary chemistries with reversible DNA-binding properties of magnetic beads. The magnetic beads, which are unique from other SPRI beads, are developed for effective nucleic acid purification by removing unwanted components such as salts, dNTPs, enzymes, primers, adapters, and other impurities. The beads are RNase free, can be used for applications of DNA, and even work with more sensitive RNA without any additional cost.
Our magnetic beads are optimized to selectively bind DNA fragments of 100 bp and larger, and RNA fragments of 200 bases and larger, similar to other SPRI beads such as AMPure® XP* and SPRIselect*. Purified DNA and RNA are suitable for downstream applications requiring high quality DNA and RNA, as the purified fragments are free of contaminants and impurities. The beads can be used for NGS library purification, PCR fragment cleanup, molecular cloning, or even nucleic acid concentration.
The beads can also be used for size selection of DNA fragments ranging from 150 bp to 800 bp by changing the bead-to-sample volume ratio and performing single or double-size selection. The beads are an ideal choice for NGS library preparation. They can be easily integrated into the standard workflow of NGS library preparation since the volume ratio is similar for protocols using standard magnetic beads.
Features:
Effective recovery of DNA and RNA samples
DNA fragments greater than 100 base pairs
RNA fragments greater than 200 bases
Removal of unwanted components and impurities
Fragment size selection for specific applications
Consistent single or double-size selection
Flexibility: compatible with manual and automated processing
Cost effective alternative to other beads such as AMPure® XP* and SPRIselect* with equivalent performance
* AMPure® XP and SPRIselect are trade marks of Beckman Coulter.
Magnetic beads recovery rate. dsDNA and ssDNA of genomic DNA, 1 kb DNA, and 200 bp DNA fragments were used. Total RNA was also tested.
Comparison of elution volume vs yield. 40 ul , 30 ul, and 20 ul of elution volume were used. BioDynami magnetic beads have better recovery rates at low elution volume when compared to other SPRI beads such as AMPure® XP*.
