(b) Number of fractions with a 5-HT hit (50 total) having total selectivity (no other hits), one other hit, two other hits, etc. (c) Percent of DAR hits (57 hits total) at each receptor subtype. (d) Number of fractions with a DAR hit (52 total) having total selectivity (no other hits), one other hit, two other hits, etc. (e) Percent of MAT hits (54 hits total) at each receptor subtype. (f) Number of fractions with a MAT hit (51 total) having total selectivity (no other hits), one other hit, two other hits, etc. (g) Percent of σR hits (144 hits total) at each receptor subtype. (h) Number of fractions with a σR hit (86 total) having total selectivity (no other hits), one other hit, two other hits, etc.
