ASP Alert Water
Fast Domoic Acid Screening for Seawater
Harmful algal blooms are increasing the need for faster monitoring of domoic acid in marine environments. ASP Alert Water helps water monitoring teams detect dissolved domoic acid in seawater quickly, simply, and with high sensitivity, supporting early warning for wildlife and public health.
Built for Seawater Testing
ASP Alert Water is designed for seawater samples where early detection of dissolved domoic acid matters. Dissolved domoic acid can be taken up by marine organisms and may contribute to intoxication events in fish, marine mammals, and other wildlife. Early detection in seawater can provide important warning before wider ecological or public health impacts occur.
Simple 1:1 Dilution Workflow
Testing is straightforward:
1. Remove any larger particulates by filtering the seawater sample.
2. Mix 2.5 mL of filtered seawater with 2.5 mL of buffer.
3. Incubate with the test reagent for 10 minutes.
4. Run the LFA for 10 minutes, and scan the result.
Sensitive Early-Warning Detection
With a detection limit of 0.1 ppb (0.1 ng/mL), ASP Alert Water provides highly sensitive domoic acid screening in seawater, with sensitivity better than many commercial ELISA options. This supports earlier monitoring of harmful algal bloom activity before domoic acid accumulation becomes a greater concern.
Results in Under 25 Minutes
Maximize efficiency with a testing protocol designed for speed. ASP Alert Water streamlines the detection process that eliminates the need for time-consuming chemical extractions. From initial filtration to the final digital reading, the entire workflow is completed in under 25 minutes, allowing for immediate on-site decision-making without the wait times of traditional lab-based methods.
Clear Digital Results
Eliminate subjectivity when paired with our handheld reader, SensoRead. The reader provides objective, digital results that ensure consistency across different operators and environments. SensoRead displays qualitative findings immediately, removing the guesswork often associated with visual interpretation of test lines in both field and laboratory settings.
