Simplified method for isolation of white cells from whole blood suitable for direct polymerase chain reaction.
A simple method for isolating mononuclear cells from whole blood is described. The procedure utilizes phytohemagglutinin to agglutinate the erythrocytes, separating white cells from whole blood in a very brief handling time. The isolated cells are readily subjected to DNA isolation simply by boiling, and the released DNA can be directly employed for the polymerase chain reaction analysis. The efficiency of this method is similar to other conventional methods, but less costly and less time-consuming. This method is particularly useful in analyzing DNA samples from the peripheral blood cells when the simplicity and low cost of the assay are preferable.
