Used PERSEPTIVE BIOSYSTEMS Cytofluor 4000 #9108088 for sale

The PERSPECIVE BIOSYSTEMS PERSEPTIVE BIOSYSTEMS Cytofluor 4000 is a multipurpose fluorescence-based spectrometer equipment that can be used in a variety of fluorescence-based applications. Cytofluor 4000 is designed to detect weak fluorescence from a variety of sample types, from proteins to dyes, as well as detection of solids, liquids, and gases. It utilizes a dual excitation beam system that employs two lasers, a green and a red diode laser, each with an adjustable excitation wavelength range of 550 nm to 680 nm. PERSEPTIVE BIOSYSTEMS Cytofluor 4000 also includes a dual-wavelength detector and a 5-position switching port that can be used for a variety of measurements, such as fluorescence resonance energy transfer (FRET) and the quantification of protein-protein interactions. The unit utilizes a variety of filters to analyze the sample and measure fluorescence emission at multiple wavelengths and can also measure fluorescence lifetimes for advanced fluorescence-based studies. Furthermore, Cytofluor 4000 is equipped with advanced software that allows control of all laser and detection parameters from one user interface. The software allows the user to easily set up experiments, view and analyze data, and print or store data for further analysis. The machine is capable of accurately and precisely measuring both the fluorescence intensity of a sample as well as the fluorescence lifetime. The fluorescence lifetime measurement can be used to measure the association and dissociation rates of proteins, allowing for insight into the dynamics of protein-protein interactions. PERSEPTIVE BIOSYSTEMS Cytofluor 4000 tool also allows for the measurement of fluorescence anisotropy, which can be used for the quantitative analysis of protein-protein interactions over time. The fluorescence anisotropy can be used to calculate the rotational correlation time (tau-c) of a sample, which is often used to determine the stability of the protein-protein interactions being studied. Cytofluor 4000 also provides several optional accessories such as a laser diode combiner, variable speed stirrers, temperature control options, and a membrane fractionation device, all of which can be used to study a variety of biological and physical processes. In conclusion, the PERSPECIVE BIOSYSTEMS PERSEPTIVE BIOSYSTEMS Cytofluor 4000 is a versatile and powerful fluorescence-based spectrometer asset that can be used to study a variety of biological and physical processes. It utilizes two lasers and a dual wavelength detector to measure fluorescence intensity and lifetime, as well as fluorescence anisotropy, allowing for the quantitative analysis of protein-protein interactions over time. The model also allows for temperature and speed control options that can be used for a variety of sample types and comes with a variety of optional accessories to expand the user's capabilities when studying a specific process.
