Background	Endothelins are peptides with receptors and effects in many body organs.Endothelin constricts blood vessels and raises blood pressure. The endothelins are normally kept in balance by other mechanisms, but when overexpressed, they contribute to high blood pressure (hypertension), heart disease, and potentially other diseases. Endothelins are 21-amino acid vasoconstricting peptides produced primarily in the endothelium having a key role in vascular homeostasis. Endothelins are implicated in vascular diseases of several organ systems, including the heart, lungs, kidneys, and brain.[4][5] As of 2018, endothelins remain under extensive basic and clinical research to define their roles in several organ systems.

Human Endothelin 1-21(ET1-21)ELISA Kit Sample preparation

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℃.
