The ability to designate the positions that specimens occupy within the MultiBrain® block provides the researcher with a unique enabling technology for analysis. Positioning can help to visualize relative gradients in stained features and can accelerate analysis.

Sample Orientation Illustration: Rat Brain Layout Array

(The dosing level by row demonstrated in this example represents one way in which you may choose to position your specimens to facilitate analysis.)

 

 

Relative location of individual brain sections on microscope slides
Use the links below to specify where sections of each specimen are to appear on the slides to facilitate comparison across treatment groups and controls. The brains will be positioned in the MultiBrain® embedding matrix such that subsequent sectioning of the MultiBrain® array yields composite sections in this pattern.

Please note: The MultiBrain® Matrix Marker preserves left-right orientation.

NSA strongly recommends that researchers designate their own positioning by selecting the appropriate form below, filling in the positions, printing the form for inclusion with shipped specimens, and sending an electronic version of the form to the email address listed on the form. If a numbering pattern is not specified, the brains will be embedded left to right in an ascending alphanumeric sequence.
