Light, moisture, and heat can degrade medications, so their shelf life is determined by how they are stored
The eluted proteins were subjected to size-exclusion chromatography (SEC) with a Superose 6 Increase 10/300 GL column (Cytiva) in the final buffer containing 25 mM HEPES pH 7.5, 150 mM NaCl and 1 mM DTT (buffer A, for biochemical assays) or 5 mM DTT (buffer B, for cryo-EM)
Understanding This Peptide 5-Amino-1MQ is a synthetic small-molecule peptide analogue designed to inhibit the activity of a key enzyme involved in the regulation of cellular NAD+ levels
LCMS/MS analysis was performed using an Advance nanoLC (BrukerMichrom, Auburn, CA, USA) and LTQ linear ion trap mass spectrometer (Thermo Fisher Scientific) equipped with a NANOHPLC capillary column C18 (0.075 mm ID 150 mm length, 3 m particle size, Nikkyo Technos, Tokyo, Japan) using a linear gradient (25 min, 535% CH 3 CN /0.1% formic acid) at a flow rate of 300 nL/min
