Octyl-beta-Thioglucoside (OTG)


Stabilizes proteins better than octyl beta-glucoside.

Octylthioglucoside (OTG)

Thermo Scientific Octylthioglucoside is a low-MW nonionic detergent that is effective for cell lysis and nondenaturing protein solubilization. It is resistant to beta-D-glucoside glucohydrolase degradation.

Highlights:

  • A low-molecular weight, nonionic detergent
  • Effective for a variety of cell lysis and protein solubilization methods
  • Unaffected by beta-glucosidase enzyme
  • More stable than octyl beta-glucoside (OG)
  • Can be removed from solution by dialysis
  • Optically clear; low absorbance at 280nm
