Rat Endothelin Receptor A (ETRA) ELISA Kit

Detect endothelin receptor A in rat samples with quantitative ELISA

Endothelin receptor type A (ETA / ETRA) is a G-protein coupled receptor that mediates vasoconstriction and is studied in cardiovascular and pulmonary hypertension models. This rat ETRA ELISA Kit from Assay Genie is tuned to quantify receptor levels in samples collected from rat experimental systems, supporting pharmacology, toxicology, and biomarker discovery workflows.

The kit provides reagents sufficient for 96 assays and is supplied in a multi-well plate format compatible with standard absorbance plate readers. Reconstituted standard and prepared samples yield signal values proportional to receptor concentration, allowing construction of a standard curve across the working range.

Suitable input materials include tissue homogenates prepared from rat organs, particularly vascular beds, heart, and lung. Aliquot samples before freezing to limit freeze-thaw cycles that can degrade membrane-bound receptor targets. Store kit components at refrigerated temperatures (4 °C) and protect from light; consult the included datasheet for component-specific handling.

For research use only. Each kit ships with an insert detailing assay procedure, dilution guidance for matrix-rich samples, and notes on validating parallelism against neat samples. Researchers studying the endothelin axis in rat models of disease can pair this assay with downstream gene expression or functional vascular endpoints.
