The Parameter Aldosterone assay is a 3.5 hour competitive enzyme immunoassay designed to measure Aldosterone in cell culture supernates, serum, plasma, and urine.
Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in twenty separate assays to assess inter-assay precision. Assays were performed by at least three technicians using two lots of kit components.
The recovery of Aldosterone spiked to levels throughout the range of the assay in various matrices was evaluated. Samples were diluted prior to assay as directed in the Sample Preparation section.

To assess the linearity of the assay, samples containing and/or spiked with high concentrations of Aldosterone were diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay. Samples were diluted prior to assay as directed in the Sample Preparation section.
Preparation and Storage
Store the unopened product at 2 - 8 °C. Do not use past expiration date.
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.
Prepare all reagents, standard dilutions, and samples as directed in the product insert.
Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.
100 µL Aldosterone Primary Antibody Solution
Add 100 µL of Aldosterone Primary Antibody Solution to each well (excluding the NSB wells). Cover with a plate sealer, and incubate at room temperature for 1 hour on a horizontal orbital microplate shaker.
Aspirate each well and wash, repeating the process 3 times for a total of 4 washes.
50 µL Assay Diluent RD1-120
Add 50 µL of Assay Diluent RD1-120 to each well.
