||
|---|---|---|---|
| Lys-481 and Ser-557 | Asn-481 and Ser-557 | Lys-481 and Asn-557 | |
| 902-12 | 181 | − | − |
| 905-12 | 11 | − | − |
| 338-41 | >512 | − | 23 |
| 2906-41 | 128 | − | 90 |
a
The number before the dash identifies the donor cat; the number after the dash identifies the month p.i. when the serum was obtained.
b
Values shown are the geometric means of the titers obtained in two independent assays. −, no neutralizing activity detected; mean titers of <8 were not considered significant and were scored as negative.
