Table 1 Bovine experimental groups

From: Immunogenicity of unprocessed and photooxidized bovine and human osteochondral grafts in collagen-sensitive mice

BColl/CFA (n = 4 for comparison to 4-week groups) (n = 4 for comparison to 12-week groups) Positive control; bovine collagen with complete Freund's adjuvant, euthanized 3 weeks after injection
BColl/IFA (n = 4 for comparison to 4-week groups) (n = 4 for comparison to 12-week groups) Positive control; bovine collagen with incomplete Freund's adjuvant, euthanized 3 weeks after injection
Bo-UP-4 (n = 7) Unprocessed bovine graft, 4 weeks implantation
Bo-P-4 (n = 8) Photooxidized bovine graft, 4 weeks implantation
Bo-S-4 (n = 4) Negative control; sham operation, euthanized 4 weeks post-op
Bo-UP-12 (n = 8) Unprocessed bovine graft, 12 weeks implantation
Bo-P-12 (n = 8) Photooxidized bovine graft, 12 weeks implantation
Bo-S-12 (n = 4) Negative control; sham operation, euthanized 12 weeks post-op
  1. B or Bo = bovine; UP = unprocessed; P = photooxidized; S = sham
