Extended Data Fig. 2: Cell-lineage tracing of the CALR mutation.
From: In utero origin of myelofibrosis presenting in adult monozygotic twins

a, Comparison of different sources of germline DNA for twin A. Automated electrophoresis for double-filtration CD3-enriched cell DNA is shown in dark blue, nail DNA in brown, single-filtration CD3-enriched cell DNA in light blue, while CD34-enriched cell DNA is shown in red. CALRdel52bp VAF was calculated 1.8%, 9.0%, 10.8%, and 37.1%, respectively. b, T cell purity assessment of the double-filtration CD3-enriched population by flow cytometry.
