Sample Preparation:

Sampleprep ID:SP000617
Sampleprep Summary:EBC: Transfer 800μl aliquots of EBC samples into a 1.5ml microcentrifuge tubes and dry down (lyophilize) each sample in a centrifugal vacuum evaporator for 4-6 h. Apply no heating during the drying process. In the dried EBC samples add 250μl of phosphate buffer and 250μl of 4mM TSP-d4 solution. Vortex for 20 s. Transfer the solution to 5mm NMR tube.
