Brief Introduction of Virus Transporattion Medium

Brief Introduction of Virus Transporattion Medium

Because of the variability of new coronaviruses, many asymptomatic infected people are only detected through accounting tests. We have developed inactivated and activated virus transportation media, which can be used for the detection of other viruses such as New Crown Flu. to help check that the sample is not damaged, so that the detection is more accurate.

The Difference Between Tris Buffer and HEPES Buffer

The Difference Between Tris Buffer and HEPES Buffer

In many biochemical experiments, it is necessary to use Good’s buffer, which can resist the influence of a small amount of strong acid and alkali, and provide the most suitable pH value for the reaction system. The most commonly used buffers are Tris buffer and HEPES buffer. Many people do not know the difference between them. Desheng company will give you an introduction:

Gold Manufacturer of Good's Buffer Phosphoenolpyruvate Tris (cyclohexylamine) Salt

Gold Manufacturer of Good's Buffer Phosphoenolpyruvate Tris (cyclohexylamine) Salt

PEP stands for phosphoenolpyruvate Tris (cyclohexylamine) salt, CAS35556-70-8, and is a member of Good's buffer (Good's buffer). Phosphoenolpyruvate (PEP) is a very important chemical substance in life activities and participates in various biochemical processes. Whether in the animal kingdom or the plant kingdom, whether in cellular respiration or photosynthesis, PEP plays a role silently.

Preparation of HEPES buffer with different concentrations

Preparation of HEPES buffer with different concentrations

Biological buffer is a solution that can keep the pH of the solution relatively stable when a small amount of acid or alkali is added. Most cells can only move in a narrow pH range, and a buffer system is needed to resist the occurrence of metabolic processes. pH changes. In the process of cell culture, HEPES buffer is often indispensable. In open culture conditions, if HEPES is added, it can prevent the pH of the medium from oxidizing to increase, thereby maintaining the pH at about 7.0. HEPES molecular weight is 238.31, chemical name: 4-hydroxyethylpiperazineethanesulfonic acid, molecular formula: C8H18N2O4S. HEPES is commonly used in biological buffers, pH buffer range: 6.8-8.2, used in biochemical diagnostic kits, DNA / RNA extraction kits and PCR diagnostic kits. Let's take a look at how different concentrations of HEPES buffer are prepared.
