Fine\u2010needle aspirates of enlarged peripheral lymph nodes were obtained from a case of spontaneous lymphoma in a pet guinea pig. Anti\u2010CD3 and anti\u2010Pax5 antibodies were validated by a combination of western blotting performed on splenic lysates of both the dog and guinea pigs, immunohistochemical studies on normal guinea pig tissues, and immunocytochemistry on normal guinea pig peripheral blood and splenic impression smears.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The antibodies bound to antigens of an appropriate size in both the dog and guinea pig splenic lysates by Western blot analysis. Immunohistochemistry and immunocytochemistry demonstrated the expected distribution of putative T\u2010 and B\u2010lymphocytes in normal tissues, peripheral blood, and splenic impression smears. As a proof\u2010of\u2010principle for its clinical utility, this immunocytochemical assay was used to diagnose a B\u2010cell phenotype in a spontaneous lymphoma case in a pet guinea pig.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Here, we validated an immunocytochemical method for immunophenotyping of lymphoma in guinea pigs as either a T\u2010 or B\u2010cell phenotype.
