WebMar 20, 2024 · Type II cryptochromes are expressed without bound FAD. We expressed and purified recombinant DmCRY (Type I) and Homo sapiens HsCRY1/2 (Type II) from Escherichia coli ().The UV-visible absorption spectrum of DmCRY shows near-stoichiometric binding of oxidized FAD (Fig. 1a), with characteristic vibrational fine structure on the … WebFeb 1, 2024 · The HTC results from additional samples enabled us to assess eight short geomagnetic events, possible cryprochrons, that are highlighted in Figure 6 and listed in Table 1. The only sample that had weak magnetization (4.26 × 10 −5 A/m) and did not clearly trend toward the origin was sample X-234 from short event 4.

This formation has a simple magnetic mineralogy dominated by magnetite and is suitable for paleointensity investigations. Magnetic susceptibility is rather uniform within the formation and is determined by paramagnetic minerals.
