The properties of molecular biology level Tris HCl
Tris HCl is a buffer solution composed of trimethylaminomethane (Tris) and hydrochloric acid (HCl). It has the following properties:
1. PH stability: Tris HCl buffer has a pH range of 7.5-8.5, indicating good pH stability. In biochemical and molecular biology experiments, the stability of pH value can ensure the experimental results.
2. Ion strength regulation ability: Tris HCl buffer can regulate ion strength, thereby affecting the solubility and stability of proteins. In protein electrophoresis experiments, the migration rate of proteins can be changed by adjusting the ion strength.
3. Chemical purity: Tris HCl has a high chemical purity, generally 99%, with an analytical purity level, which is conducive to the accuracy and reliability of experimental results.
4. Solubility: Tris HCl is easily soluble in water, forming a transparent and colorless solution. Good solubility makes laboratory operations more convenient.
Tris HCl preparation process
1. Raw material selection: The key to preparing Tris HCl molecular biology grade lies in selecting high-purity raw materials to ensure that the final product is not affected by impurities, with high-quality Tris and HCL being the foundation of preparation.
2. Preparation steps:
(1) Preparation of aminomethane: By aminating methane, aminomethane is obtained.
(2) Aminomethane sulfonation: Reacting aminomethane with sulfonic acid to form Tris.
(3) Solution preparation: Dissolve Tris powder in deionized water to obtain Tris solution.
(4) Hydrochlorate formation: React Tris solution with HCL to generate Tris HCl.
(5) Crystallization and drying: After crystallization and drying, the final Tris HCl crystal is obtained.
Application of Tris HCl at the molecular biology level
Tris HCl molecular biology level is widely used in the fields of biochemistry and molecular biology, mainly including the following aspects:
1. Protein electrophoresis: Tris HCl buffer is one of the most commonly used buffers in protein electrophoresis experiments. It has high ion strength and stability, can provide a good electrophoresis environment, improve electrophoresis resolution and accuracy.
2. DNA sequencing: In DNA sequencing experiments, Tris HCl buffer can be used as a component of DNA dissolution solution or PCR reaction solution. It can provide stable pH value and ion strength, ensuring the accuracy and reliability of DNA sequencing.
3. PCR amplification: In PCR amplification experiments, buffer solution is required to provide a stable reaction environment. Tris HCl buffer can be used as a component of PCR reaction solution, providing stable pH and ion strength, ensuring the accuracy and specificity of PCR amplification.
4. Enzyme reaction: In some enzyme reactions, such as phosphorylation and glycosylation reactions, Tris HCl buffer can serve as a part of the reaction medium, providing stable pH and ion strength to ensure the smooth progress of enzyme reactions.
Notes on Tris HCl molecular biology level
When using Tris HCl in molecular biology, the following points should be noted:
1. Storage conditions: Tris HCl buffer should be stored at 4 ℃ to avoid light exposure and oxidation. Long term storage may affect its quality, and it is recommended to use it immediately.
2. PH adjustment: During use, attention should be paid to monitoring the changes in pH value. If the pH value deviates from the required range, it should be adjusted in a timely manner. NaOH or HCl can be used for adjustment.
3. Avoid contamination: When using, be careful to avoid contamination, such as using clean containers and tools for operation. If pollution is found, immediate cessation of use and corresponding replacement measures should be taken.
4. Validity issue: Tris HCl buffer has a certain validity period and is generally recommended to be used up within six months. If not used for a long time or expired for a long time, it may cause deterioration or failure. Before use, attention should be paid to checking the expiration date and operating and using according to the instructions.
