Effect of different grades of waters on Immulina EC50. EC50 is the concentration (ng/mL) of Immulina material required to induce activation for the TLR2/TLR1 signaling pathway to levels 50% of those achieved by Pam3CSK4 (100 ng/mL). No statistically significant differences in activity were observed. Values represent mean EC50 values calculated from triplicate dose response determinations.
| Type of water | EC50 value ± SD |
|---|---|
| Endotoxin-free | 1280 ± 110 |
| Deionized | 1340 ± 470 |
| Milli-Q | 1090 ± 110 |
