Flow Cytometry: Fresh Specimens

General Recommendations for the Handling of Fresh Specimens

Specimen Required

From resected specimen, sample a piece of the tumor (non-necrotic, trim away normal tissue). (A corresponding sample should be submitted for histologic diagnosis and designated as such in the gross dictation). Place sample in minimum essential media (MEM) plus 10% fetal calf serum and 10% DMSO. (If you are using your own transport media, which does not contain DMSO, do not freeze.)


It is important not to have the sample at room temperature. Exposure to room temperature can result in degradation, which can lead to false-positive aneuploid cell populations in the sample.


The specimen label should include the patient name, identification number, and specimen source.
