Collection:
Collection ID: | CO002195 |
Collection Summary: | Cecal contents were collected on 10 uL plastic inoculation loops at the time of sacrifice, snap frozen in liquid nitrogen, and stored at -80 °C. Aliquots were kept frozen, removed from the loops and weighed. |
Sample Type: | Cecum |
Storage Conditions: | -80℃ |
Treatment:
Treatment ID: | TR002214 |
Treatment Summary: | Germ-free C57BL/6J mice were reared in plastic flexible film gnotobiotic isolators (Class Biologically Clean) at 23 °C under a strict 12-hour light cycle (lights on at 0600h, off at 1800h). Animals were weaned onto an autoclaved, low-fat, plant polysaccharide-rich chow (catalog number 2018S, Envigo) that was administered ad libitum. Five days prior to colonization, 8-week-old male mice were switched to the NAD precursor-sufficient diet; 2 days later, they were either placed on a NAD precursor-deficient diet, or a NA-supplemented diet or were continued on the NAD precursor-sufficient diet. |
Sample Preparation:
Sampleprep ID: | SP002208 |
Sampleprep Summary: | 10 uL of ice-cold methanol was added per mg of sample, which was then thawed on ice. The mixture was subsequently shaken for two minutes in a BioSpec bead beater. Samples were then centrifuged for 10 minutes at 3,000 x g at 4 °C; a 150 uL aliquot of the supernatant was transferred to a new tube containing 150 uL ice-cold chloroform, then mixed by pulse vortexing and centrifuged for 10 minutes at 3,000 x g at 4 °C. 100 uL of the methanol fraction was transferred to a new tube containing 100 uL of ice-cold chloroform, mixed by pulse-vortexing, and centrifuged for 10 minutes at 3,000 x g at 4 °C. 70 uL was transferred to a new tube and lyophilized in a Labconco SpeedVac. |
