In addition to the existing isoform ( Pax-5 , which we have named Pax-5a ), we have isolated three new isoforms, Pax-5b , Pax-5d , and Pax-5e , from murine spleen and B-lymphoid cell lines using library screenings and polymerase chain reaction amplification .
 ( protein: Pax-5b, None) , ( protein: Pax-5e, None) , ( protein: Pax-5a, None) , ( protein: Pax-5, None) , ( protein: Pax-5d, None) , ( cell line: B-lymphoid cell lines, None)
