Data from: Whole-genome sequencing of 128 camels across Asia reveals origin and migration of domestic Bactrian camels

Zhen Wang, Liang Ming, Liyun Yuan, Li Yi, Yixue Li &
The domestic Bactrian camels were treated as one of the principal means of locomotion between the eastern and western cultures in history. However, whether they originated from East Asia or Central Asia remains elusive. To address this question, we performed whole-genome sequencing of 128 camels across Asia. The extant wild and domestic Bactrian camels showed remarkable genetic divergence since they were split from dromedaries. The wild Bactrian camels also contributed little to the ancestry of...

Photoelectrochemical Immunosensor Based on ZnIn2S4/Bi2Se3 Nanocomposite for the Determination of Cardiac Troponin I

Wanxin Dong, Xinxin Mo, Yu Wang, Qin Lei & He Li
In this work, a novel flexible photoelectrochemical immunosensor is developed to determine cardiac troponin I (cTnI) in serum. The flower-like ZnIn2S4 nanospheres (ZIS), as signal amplification material, were successfully synthesized by a solvothermal method. The ZIS and Bi2Se3 were modified on the indium tin oxide- polyethylene terephthalate (ITO-PET) electrode, which effectively accelerates the electronic transition and improved the photocurrent conversion efficiency (signal on). However, the binding of antigen–antibody proteins blocks the electron transfer, resulting in...
