- Comments
- IfSi-1: Isoelectric focusing indicated the presence of both human and caribou blood in a residue on a chert knife. This possibility was subsequently confirmed by a radio-immuno-assay that yielded evidence of cervid albumen, according to G. Lowenstein. Loy also performed a bead-linked, enzyme-linked immunosorbent assay that indicated the presence of human IgG. A portion of the residue was dated by accelerator mass spectrometry.
