The strain was originally developed at the Sloan Kettering Institute where it was backcrossed on a non-specified C57BL/6 strain. The congenic strain "C57BL/6-Ly5.1" carries the allele of the SJL mouse in the Ptprc gene locus: "Ptprca" or "CD45.1" or "Ly5.1". Charles River Europe breeds CD45.1 expressing B6.SJL-Ptprca Pepcb/BoyCrl mice in Italy.
