QUESTION I find the technique of challenging the animals with various typic agents quite intriguing for assessment after prolonged exposure to MDMA or amphetamine. How long do those changes last I saw in your slide something on the order of 2 weeks or a few days after the MDMA treatment. If you would come back a few months later, would that supersensitivity still exist ... 

Many silane coupling agents can be applied to substrates by volatilization in an enclosed chamber under heat or vacuum. In this approach, the substrate is placed within the chamber in a fashion to allow for vapor phase molecules to access all areas that are to be derivatized. This method is commonly used for silanizing glass slides or substrates that are difficult to suspend in a silane solution. Slides are often placed in racks within the chamber and all surfaces get modified... 

For moving streams of particnlate matter (aggregate matter, slnrries), typically transported nsing conveyor belts or similar horizontal agents (slides, tmcks, railroad cars, etc.), the eqnivalent principal solntion is the cross-stream cutter, as is illustrated in Fignre 3.22. 

Both proteins and nucleic acids may be immobilized to a variety of solid supports. For high density microarrays, glass slides are the preferred substrates because of their flatness and optical properties. Better spot resolution is also possible on nonporous glass as opposed to porous membranes, primarily due to a reduction in diffusion at the surface-liquid interface. However, keep in mind that spot (droplet) diffusion can occur on most substrates by the actions of surfactants and other wetting agents including proteins. Control of spot size and morphology is required in order to achieve reproducible and reliable results with microarrays. 

Cut the membrane out of the insert by using a scalpel, transfer the membrane on a glass microscope slide. Glue a coverslip to the microscope slide by using a solvent-free mounting agent or nail polish. 

STEP 2 PREPARATION OF THE substrate(s). While ahnost any substrate can be used, we will use glass microscope slides in this example this is a common substrate and makes it easy to see the CdS film. The microscope slide can be cut to whatever size and shape is convenient. The slide should be cleaned well, since films usually do not adhere well to dirty surfaces. Suitable cleaning agents are trichloroethylene or/and sulphochromic acid, and the slide should be well rinsed with pure water. If the slide is clean, water dropped onto it will form a film (hydrophilic surface), while on a dirty (hydrophobic) slide the water will form drops. Needless to say, the part of the slide where deposition is to occur should not be touched with the hands after this treatment.
