A. PBMC flow cytometry confirming loss of Gal expression in GTKO animals.
B. Immunohistochemical staining of galactose-alpha-1,3-galactose was analyzed to determine adequate segregation of islets by hemiliver. At both 1 hour (p=0.05) and 24 hours (p=0.01) staining between islet phenotypes was significantly different. There was no difference in the positivity of staining from 1 to 24 hours within each phenotype (WT p=0.97, GTKO p=0.96).
C. Representative Image of α-Gal positive WT islet cluster at 24 hours.
D. Representative image of α-Gal negative GTKO islet cluster at 24 hrs.
