Figure 1. — Blood Processing. (A) Total blood from EDTA whole blood. (B) Serum from silica clot activator whole blood. C) Plasma from EDTA whole blood. (D) DNA designated EDTA whole blood. (E) RNA-designated whole blood with PAXgene collection tube. (F) Ficoll-Paque + white blood cells and plasma extraction from total blood. G) Red blood cells (erythrocytes) from EDTA whole blood. (H) Platelets from EDTA whole blood. RT, room temperature; PBS, phosphate-buffered saline; EDTA, ethylenediaminetetra-acetic acid. The tube colours depicted in the figure are representative of the colours in North America, but may not be representative of appropriate tube colours across all countries and/or institutions. This figure depicts an example of blood processing methods. However, we are aware that there are other successful biobanks with different specifications for processing. This protocol has been validated by the authors of this guideline.
