CPN550 Yellow
CPN550 Yellow (Ex-Max 470 nm/Em-Max 550 nm)
CPN550 Yellow from Stream Bio is a conjugated polymer nanoparticle with optical properties similar to Qdot nanocrystals, with optimal excitation in the UV around 325-355nm. Excitation efficiency decreases with longer wavelength excitation energy, however this means that they can be excited by multiple wavlengths. CPNs have a very high exctinction coefficient, ranging from CPNs are around 70-80 nm in size and are sold in various surface modifications including, -COOH, Streptavidin bioconjugated, EDC/ NHS, maleimide, alkene and click chemistries. In addition, CPNs contain iron oxide and are able to be analyzed by MRI.
