PHOSFINITY

Polyphosphate quantification – evolved

    The world-first kit to quantify total inorganic polyphosphate contents (polyP) in any sample including phosphate (Pi) and especially polyphosphates of any chain length.

    The Phosfinity kit is a huge advance for the field, in that it lets labs make accurate and specific polyP measurements quickly and without having to invest significant time in developing their own tools or needing the equipment to purify their own enzyme reagents. The Phosfinity kit is a phenomenal resource for the research community.

    The Phosfinity kit is a time-saving alternative to self-prepared assays for polyphosphate quantification. One can do without the time-consuming purification of the enzyme and saves the daily fresh preparation of some solutions. The kit is easy to use and ensures reproducible results.

    We are proud to have co-developed the new gold standard for the quantification of polyphosphates: PHOSFINITY.

    We are convinced it will be of great help to the phosphate community and help quantifying chemically produced polyP and polyP extracted from biological samples, such as blood, soil, water, microorganisms, plants, and more.

    USABILITY

    Any phosphate chain length

    PHOSFINITY allows to quantify the total polyphosphate content in a sample irrespective of chain length.

    PHOSFINITY can thus be used to directly measure the polyphosphate concentration in a sample within minutes – especially useful for blood, soil, plant, microbial, and water samples.

      QUICK FACTS

      Made for researchers by researchers

      We have worked (and got frustrated) with many commercially available kits ourselves – that is why we made it better:

      • Quantifies polyphosphates of any chain length
      • Quantification range between 5 to 200 µM P as polymer
      • Little sample amounts required (e.g. 200 µL of 100 µM P as polymer)
      • Quick colorimetric endpoint detection in just 2 min
      • High specificity thanks to enzymatic detection
      • No interference by commonly encountered substrates like ATP, DNA, RNA, NaCl and others
      • Pre-made Excel sheet to calculate polyphosphate contents (free download)

      HOW IT WORKS

      Enzyme innovation at work

      PHOSFINITY is based on an innovate enzyme formulation to allow the specific quantification of polyphosphate in samples.

      It was developed in close cooperation with Prof. Dr. Lars M. Blank (Head of Institute of Applied Microbiology, RWTH Aachen) and Dr. Jonas J. Christ (former Post-Doc at Institute of Applied Microbiology, RWTH Aachen), two experts in polyphosphate analytics.
