For quantitative determination of boron in agricultural and environmental samples. Key Features: Fast and sensitive. Linear detection range: 0.05 to 10 µ g/mL (0.05 - 10 ppm) boron with 100 µ L sample (96-well) . Convenient. The procedure involves adding a single working reagent. High-throughput. "Add-mix-read" type assay. Can be readily automated as a high-throughput 96-well or 384-well plate assay for thousands of samples per day. Method: OD420nm. Samples: Water, plant tisse, soil samples, and antibody conjugation solutions. Species: All. Procedure: Assay takes 40 min. Kit size: 100 tests. Detection limit: 0.05 µ g/mL or 0.05 ppm.
