| J99 genotype | Lewis B binding (relative OD units)bc
|
|
|---|---|---|
| Mean ± SD | Range | |
| Wild type | 653 ± 8 | 647–658 |
| babA2a | 8 ± 17 | <10–20 |
| babBa | 596 ± 111 | 517–674 |
Genes disrupted by insertion of aphA (Kanr) cassette in specified ORF.
Values represent the means of four separate experiments.
Relative units are expressed as OD × 1,000 as described in Materials and Methods.
