Screening for IgM/IgG antibody in giant panda blood. (A) The whole blood of giant pandas. (B) Microscopy showed normal red blood cells morphology. (C) Serologic testing yielded no positive results. Crossmatching among #15–#19 included an additional 4 °C incubation to rule out cold-reactive antibodies; results remained negative. -: negative (compatible) crossmatch: a smooth suspension of red cells after re-suspension.
