---|---|---|
Injecting Ser+ | Injecting SFS | |
50,000 | 10/10 | 10/10 |
10,000 | 10/10 | 10/10 |
5,000 | 3/10 | 9/10 |
1,000 | 0/10 | 0/10 |
100 | 0/10 | 0/10 |
NOTE: Five mice per dilution, right and left flanks were injected, for a total of 10 injections per dilution. Results at 5,000 cell dilution are significantly different (P = 0.0198, Fisher’s exact test).
