Biological Activity

Creatine phosphate disodium salt (phosphocreatine) is an endogenous phosphorylated creatine derivative that acts as a high-energy phosphate reserve in energy-demanding tissues, including skeletal muscle, heart, and brain. By transferring its phosphate group to adenosine diphosphate (ADP) via creatine kinase, phosphocreatine rapidly regenerates adenosine triphosphate (ATP) to maintain cellular energy homeostasis and sustain cellular function during metabolic stress.

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
