Operation

Once the first assay has been chosen, the software will prompt for the location
that the reader should start mapping the assay (Figure 3-49).

Figure 3-49:

Well location to begin mapping

•

Use the LEFT and RIGHT ARROW keys to move the cursor in the

editable field to the previous or next field. The cursor will wrap

around the edit field.

•

Use the ALPHA & NUMERIC keys to choose the well location to

begin the assay. Wells A-1 through H-1 are valid for ACROSS; A-1

through H-12 are valid for DOWN.

This process will be repeated for each assay within the panel. The user must be
aware of the total number of controls, standards and blanks that were originally
mapped in the “full” assay as they map the Panel assay. It is recommended that
the user first print the Assay setups for reference before mapping them in the
Panel.

For example, if the user wishes to run Assays 1, 8 and 22 within a Panel:

Assay 1 has a total of 12 wells defined for controls, blanks and
standards, and in the Panel , the mapping for Assay 1 begins in well
A01, with the map direction DOWN. The user wants to run 6 samples in
Assay 1. Assay 1 now fills wells A01 through B03.

The mapping for Assay 8 in the panel can begin in well B04, or any next
available well the user chooses. The reader will “beep” if the user tries
to map into a well that has been previously used in the panel.

The mapping for Assay 22 should begin at the next available well
location after Assay 8 mapping is complete.

After all the assays have been entered into the Panel, the user may print
the Panel assay Map. Choose Report (from the Main Menu), Map,
Assay 99. The reader will print the map of each assay configured in the
Panel.

The Panel Assay results are sorted by Sample (unless a custom assay has
been programmed by Bio-Tek). See Figure 3-49A.
