    摘要: Provided herein are reporter T-cells containing a reporter operably linked to the Nur77 locus. Also provided are methods for screening for an activity of a recombinant receptor, including those containing an extracellular antigen-binding domain and an intracellular signaling domain, such as a chimeric antigen receptor (CAR), including assessing activity of a cell expressing the recombinant receptor based on a detectable expression of a reporter molecule responsive to a signal through the intracellular signaling region of the recombinant receptor. In some embodiments, the activity assessed is an antigen-dependent or an antigen-independent activity. In some embodiments, the methods can be used to screen a plurality of reporter cells each containing a nucleic acid molecule encoding a candidate recombinant receptor, e.g. CAR, and assessing such cells for one or more property or activity. The methods can be high-throughput. Also provided are reporter cells, cell compositions, nucleic acids and kits for use in the methods.

    摘要: A plant injection system includes an injection tool configured to penetrate a plant and distribute a liquid formulation to the plant. The injection tool includes abase having an inlet port and a penetrating distribution body extending along a longitudinal body axis. The penetrating distribution body includes a penetrating element and one or more distribution ports in communication with the inlet port. The one or more distribution ports are spaced from the penetrating element. The injection tool includes penetrating and distribution configurations. In the penetrating configuration the penetrating element is configured to penetrate the plant along the longitudinal body axis. In the distribution configuration the one or more distribution ports are configured to distribute the liquid formulation to the plant transversely relative to one or more penetrating directions, at least one of the penetrating directions corresponding to the longitudinal body axis.
