The above discussion provides only a brief overview of how fluorescence techniques can be used to study the interactions of ligands with their receptors. We have focused on the quantitation of the binding parameters and compared the data with that which may be obtained with those from radiolabelled ligand binding studies. The number of applications of fluorescence in the study of neurochemistry and molecular biology is ever increasing. Outside the scope of this review is, for example, the use of fluorescence microscopy to monitor cell surface expression and targeting of receptors or the use of fluorescence probes to monitor ion transport into and out of cells. 

Gas chromatography was first coupled with a mass spectrometer in 1956 and GC/MS became commercially available in 1957 (de Hoffman and Stroobant, 2001). Examples of some of those applications pertinent to neurochemistry are listed in Table 6-1.

In conclusion, we have tried to present the principles of LCEC, describe the present applications that have been made, and survey the areas of potential utility by reviewing pertinent chemistry and related methods. It is our opinion that the success of LCEC in neurochemistry can carry over to pesticides owing not only to the advantages of electrochemical detection but also to the tremendous potential of its adjunct, liquid chromatography.

In ultrafiltration, a vacuum is applied to the probe and there is a net volume loss from the tissue sampled. One must keep in mind that the loss includes both water and solutes. Removal of fluid and neurochemicals could affect the phenomena being studied. This makes the use of ultrafiltration unsuitable for some applications, such as study of brain neurochemistry. 

Applications In medicine, food chemistry, nutrition, gastroenterology, nephrology, neurochemistry, pharmacology, excitatory amino acids are Just some topics to be listed. We also encouragethesubmission of papers... 

The potential applications of the precolumn denvatization techniques in neurochemistry are, of course, considerable. A few examples concerning release of amino acids m vitro and in vivo and levels of ammo acids in CNS fluids will be reported Finally, the usefulness of the method m the clinical routine, i e. for determination of amino acids in cerebrospinal fluid, will be touched upon briefly.
