(2-acetylamino) - iminodiacetic acid, referred to as ADA, belongs to the acetylamino Series in the buffer family. ADA powder is usually dissolved with sodium hydroxide to obtain ADA buffer, which is used for the pH value of stable solution in biochemical research. The pH value of ADA in aqueous solution is 1.5-3.0, which is acidic. When added to the experimental solution, its high activity range was between 5.8 and 7.4.
In terms of physical properties, it is a crystalline powder. ADA raw materials with good quality are white, tasteless, easily soluble in water, and the density is 1.5257g per cubic centimeter. In terms of chemical properties, ADA buffer is relatively active. It has strong ability to combine metal ions and can complex with calcium, magnesium, manganese, copper, nickel, zinc, cobalt, etc. Therefore, it is not recommended to use ADA buffer in the reaction solution requiring metal cations.
As a raw material, ADA is often used to remove sulfur dioxide from semi water gas, or as an additive in dyes. In the experiment, in order to prevent protein from being oxidized, ADA can be added to prevent irreversible reaction. As a buffer, ADA can be used to prepare amphoteric electrolytes and study myocardial contractile cells. Because of its little dependence on protein, ADA can support the survival of CEF cells even without protein in the culture medium. It should be noted that ADA cannot be used to study the activity of canine kidney because it can inhibit the activity of adenosine triphosphatase.
ADA buffer is not strong in anti-oxidation. When it is stored for a long time, it will react with oxygen in the air. Although the reaction process is slow, in order to avoid deterioration of the solution and affect the experimental results, it is recommended to use it in time after configuration. Our common packaging method is 25kg per cardboard barrel or customized packaging. ADA powder shall be stored in a closed container with a shelf life of 2 years at a temperature of 4-25 ℃.
As a manufacturer of ADA, our company continuously improves the purification technology. At present, the purity of ADA is more than 99%, the drying humidity is less than 0.5%, and the properties are excellent. Welcome new and old customers to purchase.
