At a Manhattan biohacker meetup, a tech investor described the scene: Each week, someone will bring something new and everyone will inject it
Each sample was then split into two fraction (100 L) and treated as follows: For H 2 S measurement, 100 L of each sample was precipitated with 1 mL of absolute MeOH at 40 C for 2 h, centrifuged (16,000 g at 0 C), and obtained supernatant was evaporated and the residue was resuspended and sonicated in 100 L of 50 mM HEPES buffer (pH 7.4)
For use, aspirin and L-MS were dissolved in dimethyl sulfoxide (DMSO, #13445-74, Nacalai Tesque, Kyoto, Japan) to prepare stock solutions of 1 M and 250 mM These were further diluted in the culture medium for experimental use, ensuring a final DMSO concentration of 0.2% across all treatment and control groups
The sequence is Gly-His-Lys (3 amino acids)
