Extra Small Brain Probe, DZ


Model DZ Microdialysis Probes, Good for Mice. D-I-X-0Y

Our smallest and lowest priced probe. 1.6 mm diameter x 6 mm tall body part.

  • Microdialysis membrane material is artificial cellulose “cuprophan”.
  • Use for acute studies on a stereotaxic apparatus. (If guides are necessary please use CX-I)
  • No guide cannula is available for this probe.
  • Molecular weight cut off (MWCO) is 50 kDa.

  • 1.6 mm diameter x 6 mm length of the body.
  • 0.22 mm outer diameter of the membrane.
  • Inlet and outlet connectors are attached to the probe. Works with JT-10 Tubing.

Microdialysis Probe Holder, ATH-02

  • Holds probe in the stereotaxic apparatus
Please indicate -X and -0Y value when you place an order.

  • “-X” indicates the shaft length
  • “-0Y” indicates the membrane length from body part to before the membrane.
  • If you intend to do experiment the next day, implant the DZ probe with fresh aCSF already inside, plug the inlet and outlet overnight, and then start perfusion in the morning just before your experiment. You could also start perfusing immediately at a very low rate (0.1 μl/min) and let it go overnight. Then simply turn up in the morning to begin the experiment.
  • If you want to do experiment the same day, start perfusing immediately after implantation. Experiment can typically be started after 2 hours of stabilization time.

About Microdialysis Probes


A microdialysis probe has a semi-permeable membrane. Our probes have a 220 µm outer diameter. The probe inlet connects to a syringe pump, which continuously perfuses through the probe. As the perfusate travels through the probe, analytes cross the membrane and travel out the probe outlet into sample vials on a fraction collector or to a sample loop of an analytical system via narrow tubing. This valuable tool enables the sampling of relatively low molecular weight compounds from within the extracellular space of tissues.


In the particular case of the brain and spinal cord, neurotransmitters are released to the extracellular space. This measurement has more meaning as informational transmitting than total tissue content. The collected extracellular fluid is used to determine the chemical composition with sub-nanomolar sensitivity and detect small changes due to manipulation or a physiological/behavioral change. The microdialysis-implanted animals behave close to normal conditions.
