Comet Assay IV and how it works

Using a high-definition video camera attached to your microscope, Comet Assay IV transfers a live video picture to your computer monitor. The image displayed on the monitor mirrors what you would see by looking down the microscope’s eyepiece. Any refocusing or stage movements performed at the microscope level are shown live on screen without any lag or delay.

Scoring cells with Comet Assay IV is a uniquely effortless process. Simply use the mouse to select a cell and Comet Assay IV will instantly calculate all measurement parameters and then add the data for the cell to your list of results. Click on the next cell to be scored and the process is repeated. Each scored cell within the field of view is marked with a cross to help prevent rescoring the same cell twice.

Scoring cells with Click and ScoreOnce all the cells within the current field of view have been scored, use the microscope’s stage controls and the onscreen video picture to find the next set of cells to be scored. In no time at all, you will be fluent enough with the system to score all the cells on a typical slide in two minutes.

When the required number of cells from a slide have been scored, the results can be saved in Microsoft Excel file format and used to produce reports on your collected data.

In addition to saving data to Excel, Comet Assay IV also incorporates powerful database capabilities. When used in conjunction with an Oracle database, result and audit data for each measurement is saved to the database the instant a measurement is performed.
