DTT is effective in sample buffers for reducing protein disulfide bonds prior to SDS-PAGE. DTT can also be used for reducing the disulfide bridge of the cross-linker N,N′-bis(acryloyl)cystamine to break apart the matrix of a polyacrylamide gel. DTT is less pungent and is less toxic than 2-mercaptoethanol. Typically, a seven fold lower concentration of DTT (100 mM) is needed than is used for 2-mercaptoethanol (5% v/v, 700 mM). 性质 assay ≥99.0% (RT) total impurities ≤0.3% 4,5-dihydroxy-1,2-dithiane mp 41-44 °C(lit.)   42-43 °C solubility H2O: soluble50 mg/mL, clear, colorless anion traces sulfate (SO42-): ≤50 mg/kg cation traces Ca: ≤10 mg/kg   Cd: ≤5 mg/kg   Co: ≤5 mg/kg   Cr: ≤5 mg/kg   Cu: ≤5 mg/kg   Fe: ≤5 mg/kg   K: ≤50 mg/kg   Mg: ≤5 mg/kg   Mn: ≤5 mg/kg   Na: ≤200 mg/kg   Ni: ≤5 mg/kg   Pb: ≤5 mg/kg   Zn: ≤5 mg/kg storage temp. 2-8°C 安全性 Personal Protective Equipment dust mask type N95 (US), Eyeshields, Faceshields, Gloves Hazard Codes Xn Risk Statements 22-36/37/38 Safety Statements 26-36 WGK Germany 3 RTECS EK1610000 Flash Point(F) 235.4 °F Flash Point(C) 113 °C
