Abstract
A method to assist gel analysis and processing and apparatus for the same is disclosed. The method employs a tracing/marking/measuring/analyzing and referencing template of transparent sheet material comprising of a pattern made of vertical and horizontal lines that form quadrilateral shapes upon intersection. The vertical and horizontal lines are clearly visible in white light and ultraviolet light. The template sheet(s) can be inserted in a square shaped template holding assembly (70) which is used in between a UV trans-illuminator (56) and a macromolecule resolving gel matrix (54) such as agarose or polyacrylamide gels. The template pattern can be made on one sheet of transparent material or separate sheets may contain vertical and horizontal lines and the finalized pattern can be achieved by inserting all the separate sheets in the template holding assembly. Under the UV light from UV trans-illuminator by adjusting the sheets containing vertical lines (13) according to the gel matrix'"'"'s lanes (32d, 32e, 32f) and horizontal lines (17) according to the area of interest for further analysis and processing, the adjusted pattern of lines (13) and (17) can be used as a reference even in the absence of UV light.

9. A method to assist gel analysis and processing comprising the steps of:
-
(a) Placing the template holding assembly on UV transilluminator; (b) Inserting the first template sheet having pattern of pairs of vertical lines in the first shelf slot of front panel/entry section of the template holding assembly; (c) Inserting the second template sheet having pattern of first single horizontal line in the second shelf slot of front panel/entry section of the template holding assembly; (d) Inserting the third template sheet having pattern of second single horizontal lines in the third shelf slot of front panel/entry section of the template holding assembly; (e) Placing the gel matrix after electrophoresis on the top UV transmittable transparent panel of the template holding assembly in line with the pattern of the first template sheet with pairs of vertical lines such that each pair of vertical lines represent/mark/trace the respective lane of the gel matrix; (f) Observing the combined pattern of the above said three template sheets in the template holding assembly which will be visible through the gel matrix without UV light; (g) Turning the UV transilluminator “
ON”
to emit UV light making the resolved macromolecule in the gel matrix lanes to fluoresce making its location visible in the gel matrix as well as making the combined pattern of vertical and horizontal lines to fluoresce under UV light;(h) Changing the setting of the second template sheet having pattern of first single horizontal line by moving inward or outward in accordance with setting up the upper boundary of the area of gel matrix required to be analyzed or processed; (i) Changing the setting of the third template sheet having pattern of second single horizontal line by moving inward or outward in accordance with setting up the lower boundary of the area of gel matrix required to be analyzed or processed; (j) Observing the quadrilateral shapes formed by intersection of each pair of vertical lines with first single horizontal line and second single horizontal line in the final settings visible through the gel matrix represents the areas of analysis in each lane. (k) Turning the UV transilluminator “
OFF”
to stop the emission of UV light.(l) Processing the said quadrilateral shapes corresponding to each lane, for example gel cutting by any suitable and convenient method known in the art.
