Purity: 99%
Spec 1: white powder
Application: Used as a biological buffer in biochemical diagnostic kits, DNA/RNA extraction kits, PCR diagnostic kits, as well as in buffer solutions for enzyme chemistry and HPLC separation of alkaline drugs.
Application: In biological experiments, it is an important PH stabilizing agent, usually select the appropriate weak acid and its conjugate base to get the appropriate PH value. Most biological reactions occur under neutral conditions, typically between pH 6 and pH 8, and require buffers to have effective buffer ranges between 6-8. It is also required that the acid-base form of the buffer does not chelate with certain metal ions.
Biological Buffer Features:
1, highly water-soluble
2, compatible acid-base dissociation balance
3, low cell membrane permeability
4, low metal chelating ability
5, high chemical stability
6, in the UV - visible light area has a lower absorption
