Normal human primary hepatocytes (Liver) were purchased from the Dalian Institute of Physical Chemistry (Dalian, China). Liver was cut into small pieces and digested with the appropriate amount of 0.25% trypsin at 37 °C for 2–3 min. Observed under the microscope, these cells tended to...
In this study, de novo phasing was required—not because of the absence of homologous structures, but because none of those available were sufficiently close to serve as a search model for molecular replacement. Using Tb-Xo4, a caged terbium compound, we could phase theBtiCry11Aa structure by...
Compound 2, isolated as a white amorphous powder, was determined to have a molecular formula of C37H42O20 by the positive HRESI-MS (m/z 807.2413 [M + H]+) and the analysis of the NMR data. Compound 2 showed similar NMR spectral data (Table 1) to 1 with the only difference on th...
How's it going? Joanne: Terrible. I just found out I have a chemistry test tomorrow. Kerry: Your professor didn't tell you until now? Joanne: He told us—I just didn't hear it. Kerry: What're you going to do?___ Joanne: I'll have to, because I also have an exam in French...
While studying chemistry at university, Wang Yixi often came across an experimental preparation process that he had to explain, but the amount of text was too large and abstract. As she had been interested in drawing,...
