Docetaxel-HSA Nanoformulation Preparation
Example 15
The Ratio by Weight of Docetaxel to HSA Prepared was about 1:160.
Docetaxel (2 mg) was dissolved in methanol (2.7 ml) in a glass vial to give a clear solution. A solution of HSA (320 mg, 1.6 ml) (20% human serum albumin solution for infusion (product name: AlbuRx) from CSL Behring) was added into 4.8 ml of water to give a HSA solution (6.4 ml) in a round bottom flask. The methanol solution of Docetaxel was added slowly dropwise into the flask of the HSA solution with rapid stirring at 0° C. Upon completion of the addition, a clear solution was obtained. Then, the methanol in the solution was removed under vacuum to give a clear solution. The clear water solution was filtered by a 0.22 micron aqueous phase filter. The resulting clear aqueous solution was lyophilized overnight to give a white solid.
A sample of 100 mg of the lyophilized solid was reconstituted by adding 2 mL water to give a clear solution.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
