Serum,The collected whole blood was allowed to stand at 4 degrees overnight or centrifuged(1000 x g)for 10 minutes. The supernatant was collected and stored at -20℃ or -80℃. Avoid repeated freeze-thaw cycles.

Plasma,Collect plasma using 5% sodium citrate(sodium Citrate:blood=1:9)as an anticoagulant. Centrifuge samples for 15 minutes at 1000×g at 2 - 8℃ within 30 minutes of collection. Plasma was immediately removed and tested,or stored at -20℃ or -80℃ after dispensing. Avoid repeated freeze-thaw cycles.

Urine,Aseptically collect the first urine of the day. Centrifuge to remove particulate matter,assay immediately or aliquot and store at ≤-20℃. Avoid repeated freeze-thaw cycles.

Tissue homogenates,The preparation of tissue homogenates will vary depending on the type of tissue. For this assay,tissue was rinsed in ice-cold PBS(0.01 mol/L,pH 7.2-7.6)to completely remove excess blood and weighed prior to homogenization. The tissue was cut into small pieces,a certain amount of PBS was added,homogenized with a high-speed homogenizer or other homogenizer. The resulting suspension was sonicated with an ultrasonic cell disruptor and the cell membrane was disrupted and centrifuged at 5000×g for 5 minutes. Immediately remove the supernatant and perform the assay,or dispense and store at ≤ -20℃.
