Sample 1
Four replicas of Immunoglobulin Heavy Chain cDNA from blood of a systematically healthy                 45-years old individual. Individual cDNA molecules were labeled with an unique molecular identifier                 (UMI) tag prior to library preparation. Library was then prepared according to our standardized protocol                 [http://www.frontiersin.org/Journal/10.3389/fimmu.2013.00456/abstract]. Sequencing was performed using                 Illumina HiSeq2500. Samples were de-multiplexed, the adapter sequence is                 "ACTCAGTGGTATCAACGCAGAGTNNNNTNNNNTNNNN" (UMI region is marked with N's).
