General description

Dowex 21K XLT is a strong basic anionic exchange resin, selectively adsorbs gold-cyanide complex.[1] Dowex is used as a solid acid catalyst in organic synthesis. Dowex polymer is highly efficient solid acid catalyst for the regioselective ring opening of epoxides to β-hydroxy thiocyanates.[2]

Application

Dowex 21K XLT was used:
  • to detect the existence of gold-cyanide complex using Scanning electron microscopy and Energy dispersive X-ray spectroscopy[1]
  • to remove excess amount of arsenate during the analysis of arsines using atomic fluorescence spectrometer.[3]

We identified the first enzymes that use mycothiol and mycoredoxin in a thiol/disulfide redox cascade. The enzymes are two arsenate reductases from Corynebacterium glutamicum (Cg_ArsC1 and Cg_ArsC2), which play a key role in the defense against arsenate. In vivo knockouts
