Gene trapping is used to introduce insertional mutations into genes of mouse embryonic stem cells (ESCs). It is performed with gene trap vectors that simultaneously mutate and report the expression of the endogenous gene at the site of insertion and provide a DNA tag for rapid identification of the disrupted gene. Gene traps have been employed worldwide to assemble libraries of mouse ESC lines ...
The utility and advantages of the recently introduced two-dimensional quadrupole ion trap mass spectrometer in proteomics over the traditional three-dimensional ion trap mass spectrometer have not been systematically characterized. Here we rigorously compared the performance of these two platforms by using over 100,000 tandem mass spectra acquired with identical complex peptide mixtures and acq...
One of the most important issues in water supply for agriculture or drinking is sediment control.Sedimentation in water conveyance channels reduces transmission efficiency. this study evaluated theefficiency of settling basin of Kamandan intake that is located in the village of Aligoodarz in Lorestanprovince. At first sample from water and sediment in inlet and outlet of settling basin in diffe...
