  • Convenient one-step reagent, no mixing needed
  • Extremely stable with a long shelf-life, >6 months at +4°C
  • Excellent sensitivity, ~50 pmol in 100 µl
  • Can be used in cuvette or microplate-based assays, making it ideal for high-throughput applications
  • Simple and complete kit that comes with a standardized phosphate solution for assay calibration
BIOMOL® Green provides a simple and convenient method for colorimetric phosphate quantitation (abs. 600-680 nm). Unlike other molybdate/malachite green-based assays, BIOMOL® Green doesn’t require multiple solutions or reagents prepared fresh on the day of the assay. BIOMOL® Green is extremely stable (>6 mos. at 4°C) and is simply mixed, at room temperature, with any enzymatic reaction that has released free phosphate. Reported applications include assays for phospholipid phosphatases, tyrosyl-tRNA synthetase (coupled with pyrophosphatase) and a viral RNA triphosphatase.BIOMOL® Green has perhaps been most widely applied to protein phosphatase assays. Typically, a protein phosphatase (e.g. PTP1B or LAR) is simply incubated with an appropriate phosphopeptide (e.g. IR5,9,10). Addition of BIOMOL® Green stops the reaction and begins color development, which is read 20-30 min. later. BIOMOL® Green may be used in cuvette or microplate-based assays and is ideal for high-throughput applications. Each kit comes with a standardized phosphate solution for assay calibration.
