Multistaining made easy

Kits for multistaining

FlexiStain™ maximizes the potential
of biotinylated antibodies

  • Fast – Label biotinylated Abs in solution
    in less than 10 min, no columns, washes,
    or purification steps needed.
  • Adaptable – Label less than 1 µg or up to
    several mgs of biotinylated ab, to use
    straight away or store for later use.
  • Flexible – Switch color from experiment
    to experiment. The four most popular
    fluorochromes in IHC are available.

Filter sets for multicolor separation

SpectraSplit™ upgrades your fluorescense
microscopy by adding more channels.

  • More – Expand your microscopy and move
    from 3 up to 5, 6 or even 8 color multi-
  • Easy – Just plug in the filter sets and analyze
    the most commonly used fluorochromes
    without spectral overlap.
  • Affordable – Use in existing standard micro-
    scopes. No additional software programs
    are needed.
