• protein
  • Non-reducing (without β-mercaptoethanol) SDS-PAGE analysis of UV-C irradiated HGDC samples (1 mg/ml) at different exposure times (M: protein marker, Lane 1: 0 min, Lane 2: 10 min, Lane 3: 20 min, Lane 4: 30 min, Lane 5: 40 min, Lane 6: 50 min, Lane 7: 60 min). (nih.gov)
  • proteins
  • In the case of excess 2-mercaptoethanol, the following equilibrium is shifted to the right: RS-SR + 2 HOCH2CH2SH ⇌ HOCH2CH2S-SCH2CH2OH + 2 RSH By breaking the S-S bonds, both the tertiary structure and the quaternary structure of some proteins can be disrupted. (wikipedia.org)
