Biospecimen Processing Protocol
Blood samples from biomarker participants are transported at room temperature to the Biomarkers Core laboratory for processing within 4 hours of blood draw. They are centrifuged and aliquotted into plasma, packed red blood cells, buffy coat and serum and stored at -80°. Samples collected in PAXgene tubes are transferred at room temperature to the laboratory and placed at -4° within 4 hours of the blood draw. RNA is processed within 3-5 days by the biospecimen manager using the PreAnalytix manual PAXgene blood RNA procedure. Cell lines are established and stored. CSF is available from a subset of subjects.
