2,3-Dimethyl-2,3-dinitrobutane (DMDNB, 98% purity) was purchased from Sigma Aldrich and methanol (99.9% purity) was purchased from ChemSupply Australia. A standard stock solution of 1 g/L (0.1%) DMDNB in methanol was prepared, and then serially diluted to prepare standards of 0.1 g/...
The N2-BET specific The protein used here was the bovine serum albumin (BSA) (fraction V, purchased from Sigma-Aldrich), which has an isoelectric point at pH 4.9–5.144,79 and a molecular weight of ≈ 66.5 kDa. All chemical reagents were of analytical grade, and Milli-Q water ...
