R-PE and B-PE though R-PE has found more use in flow cytometry because of this the shorthand PE is often used interchangeably with R-PE. PE has a molecular weight of 240000 Daltons with an extinction coefficient of 1960000 cm -1 M -1 and a quantum yield of 084. You may notice this in your flow cytomtetry data when measuring FITC in the presence of PE especially if using wide filters eg.
52550 BP instead of 52530 BP. Any PE signal you see in the FITC PMT is independent of the laser line. The PE channel PMT will detect light emitted from PE phycoerythrin at 575 nm wavelength.
Each PMT will also detect any other fluorochromes emitting at a similar wavelength to the fluorochrome it is detecting. Various filters are used in the flow cytometer to direct photons of the correct wavelength to each PMT Figure 5. PE-Cy5 PE overlap - PE overlap accurate PE-Cy5 results.
The procedure for setting correct fluorescence compensation is essentially the same on any cytometer but there are differences between the various available instruments which makes it. R-PE is a large molecule used for fluorescence-based detection primarily in flow cytometry microarray assays ELISAs and other applications that require high sensitivity but not photostability. In practical applications the sensitivity of R-PE conjugates is usually 5 to 10 times greater than those of the corresponding fluorescein conjugates.
One of the brightest fluorophores. Functions to transfer light energy to chlorophyll during photosynthesis in vivo. Tandem conjugate where PE is coupled to Texas Red.
Also known as ECD Electron Coupled Dye APC. Flow Cytometry Flow Cytometry is the technical process that allows for the individual measurements of cell fluorescence and light scattering. This process is performed at rates of thousands of cells per second.
This information can be used to individually sort or separate subpopulations of cells. Flow cytometry is a technology that provides rapid multi-parametric analysis of single cells in solution. Flow cytometers utilize lasers as light sources to produce both scattered and fluorescent light signals that are read by detectors such as photodiodes or photomultiplier tubes.
If the flow cytometer can sort cells the computer controls the sorting process. As data are acquired they written to the hard drive to create a file of data often referred to as listed data. The computer program can then be used to analyse data subsequent to its acquisition.
Off-line analysis is useful for the preparation of illustrations for publications lecture slides etc. Prepare your cell suspensions for Flow Cytometry. Although most flow cytometry experiments involve labeling populations of cells that are relatively abundant the number of cells required will vary depending upon the rarity of your cells.
In general researchers will stain between 1. Emission spectra of two fluorophores commonly used in flow cytometry FITC and PE are shown. Also shown is a graphical representation of two commonly used filters 52550 and 58540 to detect these fluorophores.
42-nm bandpass filter for FITC and PE respectively. As it is shown in Figure 1 FITC can be detected in the green channel FITC channel. However about 15 of the emitted photons spillover into the yellow channel R-PE channel of the flow cytometer.
On the other hand about 2 of the photons emit-. Annonse Efficient - up to 10X faster than traditional flow cytometric analyzers. 4 lasers and 14 colors rapid and sensitive detection.
