Officials in Tumxuk have gathered hundreds of blood samples from Uyghur individuals, contributing to the campaign in mass-collecting DNA.[1] Tumxuk was named a "major battlefield for Xinjiang's security work" by the state news media.[172] In January 2018, a forensic DNA lab overseen by the Institute of Forensic Science of China was built in Tumxuk.[172] Documents from within the lab showed that the lab was supported by software created by Thermo Fisher Scientific, a Massachusetts company.[172] This software was used in correspondence to create genetic sequencers, helpful in analyzing DNA.
