Polyphosphate, Long Chain (p700)

Polyphosphate, High MW (p700)

This polyphosphate (High MW, p700) is heterogeneous in size, with approximate polymer lengths ranging from ~200-1,300 phosphate units; modal size is about 700 phosphate units.

Polyphosphate, a linear polymer of inorganic orthophosphate, which is widespread in living organisms and which plays diverse roles in biology, has recently been shown to be a potent modulator of the human blood clotting system. Its procoagulant activity is dependent on polymer length; this high MW polyphosphate preparation has very high specific activity in plasma clotting assays.

In addition to being a useful tool for plasma clotting assays, polyphosphate is can be used to study bacterial growth, virulence, and bacterial membrane function.

Comments

Polyphosphate has limited solubility in the presence of divalent metal ions, so make intermediate dilutions in water, or in buffers without divalent metals or polyphosphate-binding proteins.

Reconstitution:
1 - Centrifuge 100mg tube 1 min at 1000 x g to pellet material in bottom of tube.
2 - Reconstitute in 1.0 mL purified water to make a solution of 1 M phosphate (= 102 mg/mL polyP).
NOTE: May be reconstituted in larger volumes to make a more dilute solution as needed.
