Immunoreactivity of ScFv antibodies with various synthetic peptides.

Antibody	FA-1a	FA-1b	YLP12	FA-1 antigen	Control
AFA-1	23.6–37.1a	1.4	0.1	91.0a	0.1
FAB-7	1.8	48.7–60.2a	1.1	89.5a	0.3
YLP20	0.1	0.2	27.2a	1.3	0.5
Control antibody	0.1	0.7	0.3	0.9	0.1

^aImmunoreactivity is expressed as SD units. Values with superscript a are positive (>2 SD units), and the others are negative (<2 SD units). FA-1_a epitope refers to peptides based on human FA-1_{200–219 aa} and mouse FA-1_{117–136 aa} sequences, and FA-1_b epitope refers to peptides based on human FA-1_{82–97 aa} and mouse FA-1_{2–19 aa} sequences. Control peptide is based on human FA-1_{220–240 aa} sequence.
