R-Phycoerythrin (R-PE) is a highly fluorescent protein that has become an indispensable tool in various scientific disciplines, particularly in biological research and diagnostics. Its exceptional brightness and unique spectral properties make it a preferred choice for applications requiring sensitive detection and multicolor analysis. NINGBO INNO PHARMCHEM CO.,LTD. is a leading provider of high-quality R-PE products, offering researchers the tools they need to advance their work.

The fundamental properties of R-PE contribute to its widespread use. Isolated from red algae, it is a phycobiliprotein characterized by its intense red-orange fluorescence. It can be efficiently excited by common laser lines, such as the 488 nm line, and exhibits a peak emission around 578 nm. Critically, R-PE demonstrates minimal fluorescence quenching, meaning its brightness is maintained even when conjugated to other molecules, a phenomenon that can plague other fluorophores. This inherent robustness ensures high signal-to-noise ratios in assays, allowing for the detection of even low-abundance targets.

The applications of R-PE are diverse and span multiple scientific fields. In flow cytometry, R-PE labeled antibodies are extensively used for identifying and quantifying cell populations and their associated markers. Its brightness enhances the ability to discriminate between cell populations based on subtle differences in antigen expression. Similarly, in immunoassays like ELISA and Western blotting, R-PE conjugates provide a sensitive platform for detecting target proteins, enabling more accurate quantification and earlier detection of biomarkers. Understanding the R-PE applications is key to maximizing its utility.

Furthermore, R-PE plays a crucial role in cell separation techniques, such as Magnetic-Activated Cell Sorting (MACS). By conjugating antibodies to R-PE, researchers can target specific cell types, which are then captured using magnetic beads that bind to R-PE. This process allows for the isolation of highly pure cell populations, essential for studies in immunology, stem cell research, and cancer biology. When considering R-PE purchase options, researchers often prioritize purity and fluorescence intensity to ensure effective cell sorting.

For researchers looking to source R-PE, it is vital to partner with reliable suppliers like NINGBO INNO PHARMCHEM CO.,LTD. Factors such as R-PE concentration, purity, and batch-to-batch consistency are critical for reproducible results. Exploring R-PE price and availability, especially for bulk orders or custom conjugation services, can also be important for laboratory planning. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing the scientific community with top-tier R-PE products, backed by strong technical support and a commitment to quality.
