However, the fluorophores used in flow cytometry do not adhere to the exact range of emission detected by the instrument. Therefore, compensation is generally only valid for samples that are duller. The detectors, or channels, in the instrument are designed to detect a very specific range of emissions. Estimating a low spillover fluorescence accurately is impossible (autofluorescence). When you modify the matrix, the numbers are converted to give an estimation of the amount (percentage) of spillover into the other parameter. Compensation in flow cytometry is the process of correcting for fluorescence spillover emissions. In version 4.5 and after, the matrix can be modified right in FlowJo using the "Edit/Save Matrix" menu option. In very rough terms, the 0.1803 corresponds to approximately 18% spillover (PE-%FITC).Ĭlick here for instructions on modifying the matrix. Thus, 0.1803 is the spillover coefficient between FITC and PE, or the amount of FITC signal in the PE channel for a FITC-stained cell 0.0091 is the amount of the PE signal in the FITC channel for a PE-stained cell. Compensation controls are useful for calculating a second matrix, the spillover spreading matrix or SSM. The rows are the spectra of each channel the columns are the contributions of each fluor into the channels. The subsequent lines are the spillover coefficients, corresponding to each of the channels named.

The names must match exactly use the names that appear in the $PnN keywords of the FCS file. Also what I realized that the matrix built-in Kaluza is spectral compensation so the numbers dont work in FLowjo, there is a separate.

Channels that are not in this list are not compensated channels in this list that are not in the sample are ignored. This brief guide is to help users new to compensation calculations and experienced flow-maestros alike breeze through this process in a. The second line has the names of the fluorescence channels that are being compensated. The Compensation Wizard in FlowJo is one of the most frequently used platforms, and by extension potentially the greatest source of confusion on a per-cytometrist basis.
The second line has the names of the fluorescence channels that are.
If you save the matrix to a file (using the 'Edit/Save Matrix' option), the file looks like this: The first line has the title of the compensation matrix. The first line has the title of the compensation matrix. When the 'Compute' button in the compensation matrix dialog window is clicked, FlowJo generates a compensation matrix. If you save the matrix to a file (using the "Edit/Save Matrix" option), the file looks like this: CompMatrix When the "Compute" button in the compensation matrix dialog window is clicked, FlowJo generates a compensation matrix.
