Microdialysis samples are referred to as microdialysate or just dialysate. The microdialysate is collected either manually or by the preferred method, a fraction collector. The sample is prepared for analysis by various detectors including but not limited to UV, ECD, and mass spec. More details below.

CMA Microdialysis (CMA), part of the Harvard Bioscience family of companies, is a life science research tools company devoted to the development, manufacturing, and marketing of microdialysis products. The company was formed in 1984 and was the first in the world to commercialize microdialysis … Definition of microdialysis in the Definitions.net dictionary.

Microdialysis is a minimally invasive technique allowing in vivo sampling of molecules transported into, or generated within the extracellular space of principally any tissue or organ in the body and also for sampling the body fluids such as blood or CSF. 3.0 PROCEDURE 3.1 Stereotactic Implantation of Cannulae The microdialysis procedure will be conducted once, for a period up to 18 hr. Approximately 10 hr before sample collection begins; mice will be moved to a microdialysis area within the LAF facilities where, a Cerebral microdialysis involves placement of a small catheter with a semipermeable membrane in the parenchyma of the brain, so that a dialysate fluid can be instilled into the catheter, allowed to equilibrate and withdrawn for analysis (Figure 20-1).

Microdialysis is a well established technique for chemical monitoring of brain tissue during neurointensive care. By introducing Microdialysis catheters into the brain after severe trauma or subarachnoid hemorrhage, it is possible to monitor brain tissue metabolism in the tissue at risk, i.e. the penumbra of a lesion or a region affected by vasospasm.

Several catheters may be inserted into the brain simultaneously to study different regions3. A recent cid, glutamate, and glutamine levels in 15 livers were studied during the process of retrieval, following storage during the backtable procedure, and for 48 hours postreperfusion using microdialysis. Arginase levels in donor and recipient serum were also analyzed using an enzyme-linked immunosorbent assay specific for type I human arginase.

Microdialysis is a minimally invasive technique allowing in vivo sampling of molecules transported into, or generated within the extracellular space of principally any tissue or organ in the body and also for sampling the body fluids such as blood or CSF.

A recent At present, no minimally invasive technique exists for the continuous evaluation of the biochemistry of animal and human intervertebral discs, but for research purposes microdialysis may be such a new technique. Thus, the aims of this study were to (1) evaluate if microdialysis can be used successfully in lumbar porcine disc and (2) develop a suitable procedure for the application of Microdialysis can be used in parallel to deep brain stimulation (DBS) to relate biochemical changes to the clinical outcome. The aim of the study was to use the finite element method to predict the tissue volume of influence (TVI(max)) and its cross-sectional radius (r (TVImax)) when using brain microdialysis, and visualize the TVI(max) in relation to patient anatomy. cid, glutamate, and glutamine levels in 15 livers were studied during the process of retrieval, following storage during the backtable procedure, and for 48 hours postreperfusion using microdialysis.
