Fig. 2b shows an overlay of spectra (mass window from 3,000 to 5,000 Da) resulting from C-specific cleavage of the IGF2/H19 region. Signals representing methylation events at CpGs 6-8, 10-12, 15, and 16 of the IGF2/H19 region are shown.
To calculate the cost of the chromium. contained in this material, remember that chromic oxide is. 68.42% chromium. Consequently, 1 ton of this material then. contains between 0.287 and 0.308 ton of chromium yielding. a unit value of between $325 and $348 per ton of chromium.
Chromium is a member of group 6, of the transition metals. Chromium(0) has an electronic configuration of [Ar]3d 5 4s 1, owing to the lower energy of the high spin configuration. Chromium exhibits a wide range of oxidation states, with +3 the most stable; the +3 and +6 states are the most common in chromium compounds, while +1, +4 and +5 are rare.
