Product Information
  • Brightest conjugates for Cell Imaging!

Home Algae Biotech's purified R-Phycoerythrin (R-PE) is an intensely bright phycobiliprotein isolated from newly identified algae species exclusive to the coastal region of Taiwan. It exhibits extremely bright red-orange fluorescence with high quantum yields and generates fluorescence signals far stronger than other commonly-seen organic and synthetic fluorophores.

With a broad range of excitation wavelengths, R-PE can be easily excited by two laser sources (488 nm & 561 nm), applied to most fluorescence detection instruments i.e. Flow Cytometry (FC), Immunofluorescence microscopy (IF), Microarrays.

 

Home Algae Biotech's R-PE absorbance maxima are at 496, 546, and 565 nm, its significant stokes shifts with a resolvable emission peak at 578 nm.

Benefits of R-PE
  • Ideal for multi-color fluorescent staining

    • Can be excited by two laser sources, experiments can be performed without equipment upgrades

    • Significant stokes shifts with resolvable emission spectra

    • Stable conjugation with Biotin, Streptavidin & cyanine e.g., Cy-3, Cy-5, Cy-7​ to make tandem dyes.

  • Ensure result accuracy

    • Bright Index: Level 5 with high quantum yield

    • It should be noted that the relatively high molecular weight of R-PE may preclude its use in procedures requiring good penetration into cells and tissues. It is predominantly intended for surface labeling of cells for flow cytometry.

  • Stability

    • Minimal fluorescence quenching
