Is Tris a base acid or buffer? CAS NO.77-86-1

1. Factory production, more preferential prices, regular products are available in stock;

2. DeSheng is a manufacturer of a series of biological buffer products, including Tris, Tris-HCL, Bicine, Caps, Mops, Taps, EPPS, HEPES, PEP, PIPES, MOPSO and so on. To provide you with more comprehensive services;

3. Desheng has been in the industry for 14 years. Our products are self-developed and manufactured. Biobuffer has high purity and guaranteed product quality.

4. Desheng began to do foreign trade in 2010. We have our own right to export.

When it comes to biological buffers, we have to mention Tris. It's not too much to say that Tris is a fighter in buffers. Why do we say that its powerful buffer range and application are all applauded by people The biological buffer system contains 20-30 varieties, and Desheng's main biological buffer covers several of the most important products. Such as Tris, HEPES, mops, caps, Tris HCl, etc. This article will introduce the application of Tris buffer and the matters needing attention.

Application of Tris

1. Tris is used in cosmetics. As a mild and safe cosmetic additive, it is common in some high-end cosmetics, covering Japan, South Korea, Europe and the United States.

2. Tris is used in pharmaceutical intermediates: it can form water-soluble complex salts with insoluble drugs with acidic groups, and the representative drugs are dextrorofen tromethamine, ketorolac tromethamine, etc.

1. Tris is used for activated carbon adsorption: because activated carbon has porous structure and large surface area, when the gas passes through the activated carbon and fully contacts with it, the pollutants are trapped in the pores, so as to achieve the purpose of purifying the gas. Tris can be used to prepare indoor formaldehyde adsorption materials.

4 * TRIS is used as pharmaceutical excipient: three hydroxymethyl ammonium methane (TRIS) is used as an alkaline drug for correction of acidosis, and it does not cause carbon dioxide retention.

5. It is widely used as a solvent for nucleic acids and proteins;

6. The low ionic strength of Tris buffer can also be used for the formation of intermediate fibers;

7. The "Te buffer" was prepared by adding EDTA into Tris hydrochloric acid buffer, which can be used for DNA stabilization and storage;

What should be paid attention to when using Tris

1. The pH value of Tris buffer is greatly affected by temperature and concentration, so the use environment should be considered in the preparation process;

2. To some extent, Tris reacts with various molecules, including RNase inhibitors, aldehydes, enzymes, DNA and common gold

Genera such as Cr3 +, Fe3 +, Ni2 +, CO2 + and Cu2 + can act together with heavy metals, but they also play an inhibitory role in some systems;

3. It is easy to absorb CO2 in the air, and the prepared buffer should be sealed tightly;

4. Some pH electrodes are interfered, so it is necessary to use the electrode compatible with tris solution;

5. Tris is not suitable for the determination of biquinolinic acid (BCA);

6. Inhalation, ingestion or skin absorption can cause injury. Gloves and goggles should be worn during operation.

Desheng is an old manufacturer of biological buffers. Tris is Desheng's superior product. Not only the order volume is increasing, but also the praise from customers is in constant flow. Now many manufacturers Tris are in the burst of orders, with the order volume as long as several months. Desheng's average daily output reaches tons, and the stock is sufficient. Welcome to order!
