Unfortunately, as this paper went to press the manufacturer of CF11 put column production on hold, and subsequently suspended making them indefinitely. While they may resume in the future, we are investigating and evaluating alternative inexpensive means of leukocyte depletion. For updates, please visit the Molecular Module page on the website of the WorldWide Antimalarial Resistance Network www.wwarn.org.

An alternative cellulose powder to CF11

Malaria groups at A*STAR and NUS (Singapore), Eijkman Institute for Molecular Biology(Indonesia) and SMRU (Thailand) have effectively substituted the use of CF11 with Sigma medium fiber Powder (cat # c6288) since September 2011. Preparation of the filter columns using the Sigma cellulose powder are as per Sriprawat et al 2009 (http://www.malariajournal.com/content/8/1/115) .
