Technical Overview
The SomaCount 150 uses a proprietary process based on the principle of laser-based flow cytometry to determine the somatic cell counts in a milk sample.
A milk sample is taken automatically and mixed with a fluorescent dye solution.
This dye disperses the fat globules and stains the DNA in the somatic cells.
An aliquot part of the stained suspension is injected into a laminar stream of carrier fluid.
The somatic cells are separated by the stream and exposed to a laser beam.
As the stained cells pass through the excitation source (laser beam), they begin to fluoresce creating a light pulse.
Through a series of lenses, the fluorescent pulses are focused onto a photo-multiplier tube, where they are converted into electrical pulses.
The pulses are sorted and stored by size using a micro-controller. By using a process known as pulse height analysis, the pulses are sorted, counted and translated into a somatic cell count.
The software allows for a wide variety of data output options, including diskette, serial, parallel and network connections which can be easily formatted to fit into the user’s existing system.
Operator friendly software with graphic user interface (GUI) helps make the system easy to operate.
The Somacount FC meets the requirements of IDF standards for somatic cell counting. It is an AOAC approved methodology.
What is Flow Cytometry?
Flow cytometry is a technique use to rapidly characterise and enumerate populations of bacteria, somatic cells and other particles contained in a liquid matrix.
The flow cytometer, also known as the counting assembly, includes the flow cell, microscope, narrow band filter, and one or two powerful and highly stable solid-state laser(s) and highly sensitive photomultiplier(s). The laser excites the
fluorescent marker that is intercalated into the DNA and/or RNA. The fluorescence output is then collected with optics, filtered with a narrow band filter, and detected with the photomultiplier(s). The intensity and width of the fluorescence pulses are recorded and used as gating parameters. A calibration or conversion equation can be applied to convert instruments’ gated pulses into relevant reference method official unit. The flow cytometer is compact, completely closed and temperature regulated to provide optimum stability.
