Integrating flow cytometry and labeling techniques offers a promising platform for disease diagnosis, treatment, and studies on various biological processes. CD Formulation is committed to the development of diverse liposome-based labeling products for flow cytometry, utilizing state-of-the-art technology and expertise.
Metabolic research has long been a pivotal focus within life sciences. Flow cytometry serves as a high-throughput and highly sensitive cell analysis technique that is progressively gaining widespread adoption in metabolic studies. It holds substantial relevance in areas such as infectious diseases, healthcare management, autoimmune disorders, and hematologic conditions including tumors and primary immunodeficiencies. Experiments utilizing flow cytometry techniques for tasks like cytokine detection and immune typing impose stringent requirements on diverse fluorescently labeled antibodies and fluorophore selection due to their direct impact on detection efficacy. Fluorescent-labeled liposome particles present a novel avenue for cellular metabolic investigations.

The technology of flow cytometry facilitates rapid quantitative analysis and sorting of individual cells or other biological particles (such as microspheres, bacteria, and miniature model organisms) in a liquid stream. The utilization of liposomes in flow cytometry primarily encompasses cell transfection and liposome probes.
Liposomes serve as essential tools for in vivo and in vitro delivery, primarily utilized to encapsulate synthetic cationic lipids and DNA through fusion for cellular entry. Compared to alternative methods, liposomes for DNA delivery into diverse eukaryotic cells offer superior efficiency and reproducibility. We assist our clients in developing gene therapy products based on liposomes by providing fluorescently labeled liposome products.
Fluorescein is categorized into four groups based on the excitation light wavelength, specifically 375nm, 405nm, 488nm, and 633nm. Among these, commonly used fluoresceins include those with excitation wavelengths of 488nm and 633nm, such as FITC, PE, APC, PI, etc. We are able to tailor liposome probes for flow cytometry to accommodate various fluorescence excitation wavelengths. We also provide quantum dots for multicolor labeling options, enabling multiplexed flow cytometry experiments.

Results: Liposome-targeted research necessitates the use of flow cytometry or microscopy. This aspect of the study relies on fluorescently labeling liposomes to ascertain their intracellular localization. The authors employed size exclusion chromatography (SEC) to quantitatively assess the propensity of commonly used fluorescent lipids to dissociate from liposomes during incubation in human plasma, revealing that some frequently utilized fluorescent lipid labels exhibited up to 75% dissociation, while others showed less than 10% dissociation. To evaluate the significance of this discovery, they utilized flow cytometry to measure the uptake of different fluorescently labeled liposomes by peripheral blood leukocytes and observed notable differences in uptake correlated with the trend of dissociation.
