- Endpoint:
- partition coefficient
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:

- log Pow
- Partition coefficient:
- >= 1.27 - <= 2.01
- Temp.:
- 22 °C
- pH:
- ca. 1
- Remarks on result:
- other: The six log Pow does not fall within a range of ± 0.3
- Conclusions:
- logPow for SBP1-Na is 1.64 ± 0.37
The six log Pow does not fall within a range of ± 0.3 as prescribed by the guideline - Executive summary:
The six log Pow values at 22 ± 1ºC gives a mean at 1.64 ± 0.37 which does not fall within a range of ± 0.3 as prescribed by the guideline.
