Collection ID:CO000119
Collection Summary:The cells were quenched by immediately adding a threefold volume of pre-chilled 60% (v/v) methanol solution containing 70 mM 4-(2-hydroxyethyl)-1-piperazine ethanesulphonic acid, and pelleted in a centrifuge (4,000 × g, ?4°C, 10 min)

Sample Preparation:

Sampleprep ID:SP000132
Sampleprep Summary:After quenching at –40°C, the cells were pelleted in a centrifuge (4,000 × g, ?4°C, 10 min). The pellets were washed with methanol solution and resuspended in 1 mL 35% perchloric acid to extract the metabolites from the cells. The mixture was frozen in liquid nitrogen and thawed three times. The supernatant was neutralized by adding K2CO3 solution with an initial concentration of 5 M, and an extract containing all metabolites was collected via centrifugation at 10,000 × g for 5 min at –4°C
Processing Method:Homogenization and solvent removal
Processing Storage Conditions:on ice
Extraction Method:35% perchloric acid and 5 M K2CO3
Extract Storage:-80°C
Cell Type:wildtype cells, genome shffled cells
