Abstract
This is a modified protocol for a protein precipitation method for plasma/serum samples. This protocol was originally proposed by:
Before start
Steps
Day-1/2
Thaw samples On ice
or at 4°C
Add 600µL
of 100% cold methanol to 300µL
of samples On ice
- Use 1.5-mL Eppendorf tubes
- Keep methanol cold
On ice
Vortex the samples for 0h 0m 10s
Incubate the samples at -20°C
for 0h 20m 0s
Centrifuge the samples at 4°C
at 16000rcf
for 0h 30m 0s
Transfer the supernatants to new 1.5-mL Eppendorf tubes
Dry the samples in a speed-vac concentrator
Day-2/2
Thaw the samples On ice
or in 4°C
Add 600µL
of the phosphate buffer to each sample
Vortex the samples at 4°C
for 0h 10m 0s
Centrifuge the samples at 4°C
for 0h 0m 10s
Transfer 580µL
to 5-mm NMR tubes
