Introduction
In the field of biotechnology and medical diagnostics, fluorescence-based detection plays a crucial role in cell analysis, immunophenotyping, and high-precision imaging. Among the most versatile and high-performing fluorescent proteins is Purified R-Phycoerythrin (R-PE), a phycobiliprotein extracted from Taiwanese red algae. Known for its intense orange fluorescence and high quantum yield, R-PE has become an essential fluorophore in flow cytometry, immunoassays, and fluorescence microscopy.
What Makes R-PE Unique ?
R-Phycoerythrin (R-PE) is distinguished by its:
✅ Bright Orange Fluorescence – Emission peaking at 578 nm
✅ Broad Excitation Range – Absorbs at 496, 546, and 565 nm
✅ Large Stokes Shift – Enhances spectral separation in multi-color assays
✅ High Quantum Yield – Produces strong fluorescence signals for high-sensitivity detection
Applications of R-PE in Biotechnology & Diagnostics
🔬 Flow Cytometry – R-PE is widely used in multi-color flow cytometry, where its strong fluorescence enables precise cell sorting and biomarker detection.
🧪 Antibody Conjugation for Immunofluorescence – R-PE is commonly conjugated to antibodies for high-sensitivity cell imaging and immunophenotyping.
🧫 Fluorescence Microscopy – R-PE’s bright emission enhances live-cell staining, immunocytochemistry, and confocal imaging applications.
💉 Medical & Clinical Assays – Used in ELISA, Western blotting, and fluorescence immunoassays for disease biomarker detection.
Why Choose Algae-Based R-PE ?
Unlike synthetic fluorophores, R-PE is naturally extracted from Taiwanese red algae, offering:
