Additional information

For solubility in water, OECD 105 was used as a starting point. To determine if the experiment should be outsourced to a contract lab using a qualified test method, preliminary experiments were conducted. Three lots were assessed with one replicate per lot (PF 264, PF 312, PF 321- storage condition minus 20 °C). The experiments were conducted using transaminase enzyme lyophilized powder in distilled water at 22 °C. With the initial aliquot of powder added to distilled water, there was an extremely small amount of insolubility from a component in the powder. As additional powder was added, the insoluble component increased – this continued until the mixture became a paste. Therefore, no water solubility value is reported.
