Sampling lines from 7 manufacturers were evaluated for tensile strength, rise time, and ETCO2 accuracy as a function of respiratory rate or supplemental oxygen flow rate. Biology Mass Spectrometry Analysis to Identify Ubiquitylation of EYFP-tagged CENP-A (EYFP-CENP-A) Yohei Niikura*1, Lei Fang*2, Risa Kitagawa*3, Peizhao Li1, Yao Xi1, Ju You1, Yan Guo2, Katsumi Kitagawa3 1MOE Key Laboratory of Model Animal for Disease Study, Model Animal Research Center, Nanjing University, 2Jiangsu Key Laboratory of Molecular Medicine, Medical School of Nanjing University, 3Greehey Children's Cancer Institute, Department of Molecular Medicine, UT Health Science Center San Antonio CENP-A ubiquitylation is an important requirement for CENP-A deposition at the centromere, inherited through dimerization between cell division, and indispensable to cell viability. Here we describe mass spectrometry analysis to identify ubiquitylation of EYFP-tagged CENP-A (EYFP-CENP-A) protein.
