Hazard Class IRRITANT
TAPS (CAS: 29915-38-6) is a zwitterionic buffering agent used in biochemistry and molecular biology that was selected and described by Good et al. Used in biochemical diagnostic kits, DNA/RNA extraction kits and PCR diagnostic kits. It is part of the Tris family of buffers and is useful for a pH range of 7.7~9.1. TAPS is commonly used in capillary electrophoresis to analyze DNA and in planar chromatography to separate dyes. It is the preferred culture media buffer used for dinoflagellate experiments, allowing for minimal pH change and maximal growth. TAPS may form a complex with some common metals so stability constants and concentrations should be taken into account when choosing this buffer. TAPS is capable of inhibiting connexin channels in animal cells. The activity of various carbonic anhydrases has been studied using TAPS physiological buffer, pKa=8.4 at 20℃.
