Products specifications
Species Guinea pig
Format 96T
Sample Type Serum, plasma, tissue homogenates, cell lysates, cell culture supernates and other biological fluids.
Assay Length 2.5 h
Detection Range 6.17-500pg/mL. The standard curve concentrations used for the ELISA’s were 500pg/mL, 166.67pg/mL, 55.56pg/mL, 18.52pg/mL, 6.17pg/mL
Sensitivity 2.82pg/mL
Specificity This assay has high sensitivity and excellent specificity for detection of Endothelin 1 (EDN1). No significant cross-reactivity or interference between Endothelin 1 (EDN1) and analogues was observed.
Intra-Assay Precision <10%
Inter-Assay Precision <12%
Storage Temperature -20 °C
Shipping Conditions 2-8 °C
Handling Instruction The activity loss rate (stability) of this kit is less than 5% within the expiration date under appropriate storage conditions. To minimize extra influence on the stability, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. When not in use, kit components should be refrigerated. All reagents should be brought to room temperature before use. It is recommended that all standards, controls, and samples be run in duplicate. Do not mix or interchange different reagent lots from various kit lots.
Test Principle This assay employs the competitive inhibition enzyme immunoassay technique. An antibody specific for Endothelin 1 (EDN1) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between Horseradish Peroxidase (HRP) labeled Endothelin 1 (EDN1) and unlabeled Endothelin 1 (EDN1) (Standards or samples) with the pre-coated antibody specific for Endothelin 1 (EDN1). After incubation the unbound conjugate is washed off. The amount of bound HRP conjugate is reverse proportional to the concentration of Endothelin 1 (EDN1) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Endothelin 1 (EDN1) in the sample.
Notes All kits are custom made on-demand. Please allow 10-15 working days for production and 2-3 days for shipment.

Instruction manual1

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Endothelin 1 (EDN1) and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.

Matrices listed below were spiked with certain level of recombinant Endothelin 1 (EDN1) and the recovery rates were calculated by comparing the measured value to the expected amount of Endothelin 1 (EDN1) in samples.
