Pierce™ DTT (ditiotreitol)

Preparing 1 M DTT:
1) Dissolve 3.09 g DTT in 20 mL distilled H2O.
2) Dispense into 1 mL aliquots.
3) Store the aliquots at -20 degrees C.
Note: Upon thawing the vial, there may be some precipitation that can be re-dissolved by warming and mixing.

Prepare 1 mg/mL antibody in 7.0 M Guanidine HCl, 100 mM Tris, pH 8.3. For reduction, add DTT (Cat. Nos. A39255, 20290) solution at 10 mM final concentration and incubate for 30 mins at room temperature. For alkylation, add sodium iodoacetate at 20 mM final concentration and incubate in the dark for 20 mins at room temperature. Perform buffer exchange followed by digestion using Pierce MS grade Trypsin, Cat. Nos. 90058, 90057 (1:10 enzyme to substrate ratio).
