The COMET software uses the "Comet-Assay", a fast, highly sensitive fluorescent method, to examine damage and/or repair of DNA at an individual cell level. This assay has critically important applications in the fields of toxicology and epidemiology. These range from aging and clinical investigations to genetic toxicology and molecular epidemiology.
BENEFITSThe Comet-Assay can be effective on extremely low numbers of eukaryotic cells (<10,000 cells). The time interval from execution to analysis is relatively short (within a few hours). It is
highly sensitivity requiring
<5 cGy gamma rays. Data
gathered is on a single cell basis. The
method is fast, simple, and economical.
ANALYSIS
Single
cell computerized analysis allows for appreciation of the slight
differences that other methods would have difficultly obtaining. Images
captured from the microscope use a special frame integration CCD
camera designed to capture the low levels of fluorochrome light
for the analysis. The
Comet software allows you to set the gray level threshold for separating
the cells from background. COMET will automatically extract
all the cells and display them to you thus allowing you to remove
any unwanted ones. Image
acquisition, cell selection and comet analysis may be performed
at different times in order to optimize laboratory activities and
research requirements.
FEATURES
Comet
analysis, in only a few seconds, measures the following statistics:
All
of these statistics are easily transferable to Microsoft Excel (or
other office type programs) by a simple push of a button.
INSTRUMENTATION
There
is no need of special instrumentation to perform the Comet-assay.
Many laboratories already have the necessary equipment installed.
