BCTB Blood Samples on Blood Spot Cards

This BCTB blood sample subcollection consists of whole blood samples on Blood Spot cards. A small drop of blood is placed on a pre-marked circle on absorbent paper and allowed to dry, then the paper is stored. This preserves DNA and protein found in blood.本BCTB血液样本子集合包含血斑卡（Blood Spot cards）上的全血样本。将一小滴血液滴加至吸水纸上预先标记好的圆圈区域内，待其自然干燥后对该吸水纸进行保存，该方式可留存血液中的DNA与蛋白质。
