Abstract: The present inventors have successfully prepared a library consisting essentially of a plurality of antigen-binding molecules differing in sequence from each other, the antigen-binding molecules each comprising an antibody variable region that has binding activity against a first antigen and a second antigen different from the first antigen, but does not bind to the first antigen and the second antigen at the same time. Use of the library of the present invention allows the obtainment of a variable region having enhanced ability to bind to the first antigen and the production of a bispecific antibody against the first antigen and a cancer antigen. Moreover, the present inventors have also successfully prepared an antigen-binding molecule comprising an antibody variable region that has binding activity against three different antigens, but does not bind to these antigens at the same time.

Abstract: Techniques Nuc-seq, Div-Seq, and Dronc-Seq are allow for unbiased analysis of any complex tissue. Nuc-Seq, a scalable single nucleus RNA-Seq method, can sensitively identify closely related cell types, including within the adult hippocampus. Div-seq combines Nuc-Seq with EdU-mediated labeling of proliferating cells, allowing tracking of transcriptional dynamics of newborn neurons in an adult neurogenic region in the hippocampus. Dronc-Seq uses a microfluidic device to co-encapsulate individual nuclei in reverse emulsion aqueous droplets in an oil medium together with one uniquely barcoded mRNA-capture bead.

Abstract: Provided herein are methods that enable parallel evaluation of multiple functional nucleic acids in individual cells or subpopulations of cells, in the context of incubation with other types of single cells. The key insight is concurrent measurement of polynucleic acids derived from small populations of at least two different cell types, such that function in one cell type is linked to the clonal identity of another cell. These methods simultaneously process thousands, millions, or more single cells or small populations of cells. The method integrates molecular, algorithmic, and engineering approaches. This invention has broad and useful application in a number of biological and medical fields, including immunology and drug discovery.
