Abstract: The present disclosure relates to nanoparticles containing cellular membrane and uses thereof. The nanoparticle comprises an interior compartment (or an inner core) and an outer surface (or shell) comprising a cellular membrane derived from a cell, said interior compartment (or an inner core) not providing a solid support to said cellular membrane in said outer surface (or shell). The present disclosure also relates to processes of making the nanoparticles. The present disclosure further relates to compositions comprising the nanoparticles and methods of using the nanoparticles.

Abstract: The present invention relates to methods and compositions for quantifying hemoglobin using, inter alia, a peroxidase substrate and hydrogen peroxide.

Abstract: The present invention relates to methods, combinations and pharmaceutical compositions for treating or preventing a hemolytic disease or condition in a mammal, wherein: said hemolytic disease or condition is caused by an attack of said mammal's red blood cells by said mammal's own body, or said mammal is a pregnant mammal and said hemolytic disease or condition of a fetus of said pregnant mammal is caused by an attack of said fetus' red blood cells by an antibody of said pregnant mammal, or said mammal is a baby and said hemolytic disease or condition of said baby is caused by an attack of said baby's red blood cells by an antibody of said baby's mother. The exemplary hemolytic diseases or conditions include hemophagocytic lymphohistiocytosis, an autoimmune disease or condition, or a hereditary hemolytic disease or disorder.

Abstract: The present invention relates to methods and compositions for monitoring a cellular membrane or a cellular membrane coated nanoparticle after in vivo administration.
