PolySciTech® is proud to present high quality fluorescent dyes and probes. The probes have excellent quantum yields and high brightness—to make even minute structures inside cells visible under fluorescent microscopy.
The P-series fluorescent tags attach to proteins and serve as light-emitting labels allowing the proteins to be tracked. These fluorophores bind via a vinyl sulfone functional unit to amines and thiols under slightly basic condition rendering an antibody, protein marker, or other moeity fluorescent to aid in microscope visualization.

FPI-749 and PolyVivo intermediate AI10
This animation compares two processed images of a mouse injected with FPI-749 to produce a fluorescent subcutaneous locator in the right shoulder. The injection area was marked with indelible ink which can be seen in both the visible-light and near-infrared (IR) images. The FPI-749 appears as brightly illuminated spots in the near-IR picture. Details are available in Near-IR imaging of FPI-749 conjugated PLGA microparticles. The chart on the right shows where FPI-749's emission wavelength falls in the spectrum.
