PubMed Commons is an experimental system of commenting on PubMed abstracts, introduced in October 2013. Comments are displayed on the abstract page, but during the initial closed pilot, only registered users can read or post comments. Any researcher who is listed as an author of an article indexed by PubMed is entitled to participate in the pilot. If you would like to participate and need an invitation, please email info@biomedcentral.com, giving the PubMed ID of an article on which you are an author. For more information, see the PubMed Commons FAQ.

Correction for paclitaxel extraction

Culture broth was extracted with dichloromethane and mycelia was freeze-dried, pulverized and extracted with dichloromethane. Solvent was removed by reduced pressure at 36°C and the extracts were pooled. To the final crude extract, 0.344 g, 50 mL of water was added, and the mixture separated on C-18 cartridge (Fisher) with vacuum. Methanol was used to rinse the C-18 cartridge and elute the solution that contains paclitaxel. The methanol solution was dried (0.256 g) and dissolved in methanol or acetonitrile to 200 μg/μL after which it was filtered through a 0.45 nm filter.
