摘要： Methods and devices for producing a population of liposomes are provided. Aspects of the methods include applying a centrifugal force to a suspension of liposomes in a manner sufficient to pass the liposomes through a porous membrane to produce a population of liposomes. Aspects of the invention further include devices, systems and kits useful for performing the methods.

摘要： Drug-loaded microbead compositions including a plurality of individual microbeads of a biodegradable material, a plurality of individual vesicular agents, a first therapeutic agent, and a second therapeutic agent different from the first therapeutic agent. The vesicular agents include at least one lipid bilayer surrounding a vesicular core. The first therapeutic agent is associated with the individual vesicular agents. For example, the first therapeutic agent may be contained within the individual vesicular agents or may be associated with the individual vesicular agents by ionic or non-covalent interaction. The second therapeutic agent is different from the first therapeutic agent and contained within the individual microbeads or associated with the individual microbeads through ionic or non-covalent interaction. The second therapeutic agent may or may not be associated with the individual vesicular agents. Drug-loaded biodegradable microbead compositions include microbeads of biodegradable material and a therapeutic agent associated with N the microbeads.

摘要： Methods of quantitating extra-cellular vesicle surface markers are provided. Aspects of the methods include comparing: a mean fluorescence intensity of a surface marker of interest (surface marker MFI) of a labeled extra-cellular vesicle (EV) sample with a calibration plot obtained from a liposome calibration composition to quantitate the surface marker on extra-cellular vesicles of the EV sample. Also provided are compositions that find use in practicing embodiments of the invention.

摘要： Methods of determining whether a sample includes an antibody that binds to a coronaviral antigen are provided. Aspects of the methods may include combining the sample, a mammalian cell displaying on a surface thereof an antigenic determinant of the coronaviral antigen that is specifically bound by the antibody, and a labeled secondary binding member that binds to the antibody to produce an assay composition; and flow cytometrically assaying the assay composition for the presence of a signal from the labeled secondary binding member to determine whether the sample includes the antibody. Also provided are methods of assessing a subject for an immune response to a coronaviral infection and methods of producing a mammalian cell displaying on a surface thereof an antigenic determinant of a coronaviral antigen. Also provided are systems, expression vectors, mammalian cells, and kits for practicing the subject methods.
