Knowledge you need to know before purchasing Good’s buffer

2019-05-31 来源:亚科官网
Good's buffer is a zwitterionic buffer. These buffers are generally sulfamic acid organic compounds. After being formulated into a solution, the pH is relatively stable and does not react with various enzymes and chemical reagents. It is mainly used in biology and medicine.
Good’s buffers have the following commonalities:
(1) High solubility in water;
(2) The acid-base dissociation constant (pKa value) is stable, generally at 6~8, the ability to release protons is stable, and is less affected by ion concentration, solution composition and temperature;
(3) It has low cell membrane permeability and is not easy to penetrate biofilm;
(4) capable of chelation with low molar mass metal ions, but not precipitation with metal ions;
(5) high chemical stability;
(6) Low light absorption in the ultraviolet and visible wavelength ranges;
(7) It is less likely to cause salting out with organic polymers in living organisms;
(8) High purity salts are readily available;
(9) Does not participate in the biochemical reaction process and does not interfere with the biochemical reaction process.
