Category: Cell Culture Protocols: Cell Culture Contamination Prevention and Removal Protocols

This method is advantageous for saving the occasional cultures that become contaminated. Yeast contaminated cultures will appear cloudy when slightly shaken and lymphocytes will not cluster together as much as normal. If cultures are suspect, a drop of culture can be streaked on a YPD media plate to check for growth of yeast colonies, or a 5 ml sample can be taken to Barnes Diagnostic Center for identification of yeast strain. - [Read Removal of Yeast Contamination from Lymphoblast Cultures Protocol]
