10 godz. temu · Microgravity has been shown to be an excellent tool for protein crystal formation. A retrospective analysis of all publicly available crystallization data, including many that have not yet been published, clearly demonstrates the value of the microgravity environment for producing superior protein crystals. The parameters in the database (the Butler Microgravity Protein Crystal Database ...

1 dzień temu · We describe the development and initial characterization of a digital waveform scanning quadrupole mass filter (digital QMF) used for inductively coupled plasma mass spectrometry (ICP-MS). Unlike a conventional voltage scanning QMF, in the digital QMF, the frequency of the digital waveform is scanned to filter ions with different m/z through the quadrupole, and m/z is proportional to 1/f2. In ...
3 dni temu · RAD51 is a core factor for homologous recombination to repair DNA double-strand breaks and overexpressed in breast cancer cells. Truncated peptide BRC4 (1523-1537) was obtained by computer simulation which had the highest binding free energy targeting RAD51. To enhance the binding affinity to the target protein, six nicotinic acid derivatives were modified at the N-terminal of BRC4 (1523-1537 ...
