CPN™ - Conjugated Polymer NanoparticlesWith immensely bright emission properties and highly specific targeting capabilities, our non-toxic CPN™ molecular probes have many advantages over traditional dyes in a variety of R&D applications, including in vitro imaging and labelling.
CPNs™ are highly fluorescent nanoparticles containing semiconductor light emitting polymer (LEP) cores encapsulated within a water friendly capping agent. With fluorescent properties significantly exceeding those of other molecular probes and labeling agents, CPNs™ offer immense brightness due to exceptional extinction coefficients and outstanding photo-, thermo- and chemical stability. CPNs™ have shown no toxicity and are ideal for use with live cell systems and are enabled with surface accessible carboxylic groups for the conjugation of a wide
range of molecules including antibodies, streptavidin and nucleic acids. This allows CPNs™ to be used in a diverse array of binding and targeting applications, such as flow cytometry, immunohistochemistry, immunocytochemistry, and high content screening. CPNs™ also incorporate iron oxide, allowing for magnetic manipulation, purification and quantification of bound molecules or cells, and use as contrast agents in MRI. CPNs™ are currently available in a range of fluorescence emission wavelengths from 450 nm to 680 nm.
