Colony counter imagej for mac6/17/2023 Next, in the cell concentration calculator, click on Count Cells and in the popup window, select a folder to be counted. The resolution and magnification of each image must be the same as was for the volume calibration image. Now, capture five to ten non overlapping images of the central region of the hemocytometer. Slightly visible hemocytometer lines are acceptable. Then, further adjust the exposure so that the cells are not overexposed. Finally, click the Save button to complete the calibration of the plugin.įor sample analysis, load 10 microliters of cells into both chambers of a hemocytometer slide and adjust the focus so that the interior of the cells are darker than the cell membrane to provide focus within the central cross-section of the cell and not at the poles. Then, click on the Calculate Image Volume button to output the image volume into the image volume text box. Now, type the value from the length column into the p-square length text box in the cell concentration calculator. Then, push the M key to display the results window. Next, select the straight line tool and draw a straight line across the entire length of the hemocytometer's primary p-square by clicking and dragging the cursor. This action fills in the image width and height text boxes with the image resolution in pixels. In ImageJ, under the cell concentration calculator, open the image and click on the Get Image Dimension button. ![]() Now place a standard hemocytometer onto the microscope stage and capture an image for the image volume calibration step. Then, within the microscope software, set the image capture settings to their default values. ![]() Switch to the 4x objective and ensure that the phase contrast filters are in use. To begin, set the microscope illumination to maximum. The main advantage of this method, is that it provides fast and accurate cell counts while including multiple filters and analysis tools. This protocol can help researchers quantify cell number required for common techniques and in vitro cell motility assays. The overall goal of this protocol is to use digital analysis tools to quickly make accurate counts of cells in a suspension or on a migration in an invasion assay membrane.
