Whole blood contains numerous cell forms (white cells, red cells, and platelets) that contribute their miRNA content to the sample becoming analyzed, confounding interpretation of benefits. Because of this, serum or plasma are preferred sources of circulating miRNAs. Serum is obtained following a0023781 blood coagulation and contains the liquid portion of blood with its proteins and other soluble molecules, but without the need of cells or clotting aspects.
