Product Summary
The Quantikine Endothelin-1 immunoassay is a 4.5 hour solid phase ELISA designed to measure ET-1 in cell culture supernates, serum, plasma, and urine. It contains synthetic ET-1 and antibodies raised against synthetic ET-1. This immunoassay has been shown to accurately quantitate synthetic and naturally occurring ET-1.

Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision.

    Store the unopened product at 2 - 8 °C. Do not use past expiration date.
Background: Endothelin-1
Endothelin-1 (ET-1) is produced by many tissues including lung, kidney, brain, endocrine glands, and placenta. It is also expressed by several cell types including, mast cells, endothelial cells, epithelial and smooth muscle cells. The most prominent source is vascular endothelium. ET-1 is best known as a potent vasoconstrictor. Elevated blood ET-1 levels are associated with a variety of diseases, possibly as a function of a stress response.

    Assay Procedure
    Refer to the product for complete assay procedure.

    Bring all reagents and samples to room temperature before use. It is recommended that all samples, standards, and controls be assayed in duplicate.
    1.   Prepare all reagents, standard dilutions, and samples as directed in the product insert.
    2.   Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.

    3. 150 µL Assay Diluent
    4.   Add 150 µL of Assay Diluent to each well.

    5. 75 µL Standard, Control, or Sample
    6.   Add 75 µL of Standard, control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 1 hour on a horizontal orbital microplate shaker.
    7.   Aspirate each well and wash, repeating the process 3 times for a total of 4 washes.

    8. 200 µL Conjugate
    9.   Add 200 µL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 3 hours on the shaker.
    10.   Aspirate and wash 4 times.

    11. 200 µL Substrate Solution
    12.   Add 200 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes on the benchtop. PROTECT FROM LIGHT.

    13. 50 µL Stop Solution
    14.   Add 50 µL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm.
