Abstract: The present disclosure provides CD19 binding molecules that specifically bind to CD19, including monospecific, bispecific and trispecific binding molecules, conjugates comprising the CD19 binding molecules, and pharmaceutical compositions comprising the CD19 binding molecules and the conjugates. The disclosure further provides methods of using the C19 binding molecules to treat diseases and disorders associated with expression of CD19. The disclosure yet further provides recombinant host cells engineered to express the CD19 binding molecules and methods of producing the CD19 binding molecules by culturing the host cells under conditions in which the CD19 binding molecules are expressed.

Abstract: The present invention relates to the use of split caspase proteins to determine whether or not promoters are coordinately active, whereby the transcriptional expression of incomplete portions of a caspase protein is controlled by different promoters and coordinate (not necessarily contemporaneous) promoter activity results in formation of an activated caspase protein and, consequently, apoptotic cell death. The present invention further provides for the use of an additional promoter element controlling expression of a “caspase neutralizing protein,” which, when present, inhibits the apoptotic effect of the assembled caspase subunits. Rescue of cells that actively transcribe the complementary caspase subunits indicates that all promoters of the system are coordinately active. The present invention, in non-limiting embodiments, may be used to selectively ablate cells in the context of cultures as well as intact organisms, and provides means of demonstrating coordinate activity of multiple promoters.
