BCR clustering in INPP5B^{Degron/Degron} cells stimulated on glass coverslips presenting surrogate antigen. Related to Fig. 1. Vehicle- or auxin-treated INPP5B^{Degron/Degron} cells, prelabeled for BCR, were imaged by TIRF microscopy during their interaction with antibody-coated coverslips. The video is displayed at 100 frames/s. Scale bar, 10 μm.
