STAR 635P

STAR 635P (Ex-Max 633 nm/Em-Max 654 nm)

abberior STAR 635P was the first member of an entirely new class of fluorescent dyes introduced exclusively by abberior: the class of phosphorylated fluorescent dye. This dye excels in its photophysical parameters, it is very bright, very photostable and its high water solubility enables basically background-free imaging. abberior STAR 635P can be excited with lasers at wavelength between 630 - 650 nm. For STED, a depletion wavelength around 750 - 800 nm is recommended. abberior STAR 635P is the ideal partner for abberior STAR 580 or abberior STAR ORANGE to obtain optimal 2 color STED results. Our abberior STAR 635P can substitute ATTO® 647N, Alexa Fluor® 647, or Cy5®. Best results are obtained with freshly prepared samples.
