Calculate the molecular mass (in amu) of (NH4)2CO3. Determine the formula weight (molecular mass) of the substance bromine, Br2. Given a compound's molar mass (99 g/mol) and elemental percent composition (48.5% C, 5.05% H, 14.1% N, and 32.3% O by mass), determine the...
The molecular mass of the particles in solution was estimated as described above using the Porod volume (43). As shown in Fig. 1c, the increase in iron concentration resulted in an increase in the Porod volume, essentially in the same manner as for wild-type Yfh1. This demonstrates that ...

The capacity of marine organisms to adapt and/or acclimate to climate change might differ among distinct populations, depending on their local environmental history and phenotypic plasticity. Kelp forests create some of the most productive habitats in th
For protein analyses, bands of interest were excised from SDS-gels, digested, and purified as described previously [13,26]. To identify the Cro repressor, high-pressure liquid chromatography (HPLC) coupled to mass spectrometer was used, and automated MS-MS fragmentation was performed during the ...
High resolution mass spectra (ESI +/−) were recorded on an Impact IITM instrument (Bruker Daltonics). No-carrier-added (n.c.a.) [18F]fluoride (t1/2 = 109.8 min) was produced via the [18O(p,n)18F] nuclear reaction by irradiation of [18O]H2O (Hyox 18 enriched water, Rotem ...
Protein standards of the indicated molecular mass (kDa) are shown on the left. The spectral properties of affinity purified CYP74D1 were typical of low spin cytochrome P-450. The UV-visible spectrum showed a Soret band at 416 nm and minor shoulders at 531 and 578 nm (Fig.6 A). ...
