  • How to Overcome Minor Issues in Anchorage-Independent Assays ...

    Recovering Soft Agar Colonies. Growing back soft agar colonies from the agar is a big hassle. Generally, these colonies do not grow as the agar settles on the plate. To avoid that, use the back of the 200 µl tip and punch the colony lightly to get as little agar as possible. Then, add PBS to the tube containing the colony and centrifuge at 500 ...
