hDp56-bearing animals have Unc-13 phenotype, and segregate Unc-13 and Dpy-5 Unc-13 progeny. Pick Unc-13 and check for correct segregation of progeny to maintain. This strain was generated by the Genetic Toolkit project, which should be acknowledged in any publications resulting from its use: The Genetic Toolkit is funded by the NIH National Center for Research Resources (NCRR) (USA) to Ann M. Rose, David L. Baillie, and Donald L. Riddle. Report all experimental results to Ann Rose.
