General description

PIPES (1,4-Piperazinediethanesulfonic acid) is a zwitterionic buffer. It is a stable buffer and is used majorly in fixation solutions. PIPES is inert towards enzymatic and non-enzymatic reactions. However, it generates artefacts in transmission electron microscope imaging.

Application

PIPES (1,4-Piperazinediethanesulfonic acid) dipotassium salt has been used as buffer for fluorescence polarization microscopy studies of kinesin-microtubule binding. It is suitable for use as a component of PHEM buffer ([K-PIPES], HEPES, EGTA, and MgSO4) used during rinsing and blocking steps in immunofluorescence imaging of HeLa cells. It is also suitable for use as buffer for purification of tubulin.

Cancer cells break tissue barriers by use of small actin-rich membrane protrusions called invadopodia. Complete invadopodia maturation depends on protrusion outgrowth and the targeted delivery of the matrix metalloproteinase MT1-MMP via endosomal transport by mechanisms that are not known. Here
