The Guinea Pig ET-1 (Endothelin-1) ELISA Kit is a reliable tool for the accurate quantification of endothelin-1 levels in guinea pig serum, plasma, and cell culture supernatants. With its high sensitivity and specificity, this kit delivers precise and reproducible results, making it suitable for a wide range of research applications. Endothelin-1 is a potent vasoconstrictor peptide that plays a crucial role in regulating vascular tone and blood pressure. Dysregulation of endothelin-1 has been implicated in various cardiovascular diseases, pulmonary hypertension, and kidney disorders.
Therefore, studying endothelin-1 levels can provide valuable insights into these conditions and aid in the development of potential therapeutic interventions. Overall, the Guinea Pig ET-1 ELISA Kit offers researchers a convenient and accurate method for studying the role of endothelin-1 in guinea pigs, facilitating groundbreaking discoveries in the field of vascular biology and cardiovascular research.

Note: The below protocol is a sample protocol. Protocols are specific to each batch/lot. For the correct instructions please follow the protocol included in your kit.
Step
Procedure
1
Reagent & Plate Preparation: Equilibrate TMB substrate for 30 minutes at room temperature. Prepare standards, samples (minimum 1:2 dilution), blanks, assign wells, and pre-wash the plate twice.
2
Sample & Biotin-Antibody Binding: Add 50 µL standard or sample followed by 50 µL biotin-labeled antibody to each well. Mix gently and incubate at 37°C for 45 minutes.
3
Washing: Wash the plate 5 times with wash buffer, allowing 1 minute soak time per wash.
4
Color Development: Add TMB substrate and incubate in the dark at 37°C for 10-20 minutes until color develops.
5
Stop Reaction: Add stop solution to terminate the reaction. The color changes from blue to yellow immediately.
6
Reading: Measure absorbance at 450 nm using a microplate reader.
