Provided herein are cells, methods, kits and articles of manufacture, including those related to assessing the potency of viral vectors. The present disclosure relates to a method for screening for potency of a viral vector, including vectors which encode recombinant receptors that contain an extracellular antigen-binding domain and an intracellular signaling domain, such as a chimeric antigen receptor (CAR). The methods include assessing potency of a viral vector based on a detectable or measurable expression or activity of a reporter molecule(s) that are responsive to a signal through the intracellular signaling region of the T cell receptor e.g., recombinant receptor.
