So, all that being said, should you buy it? Well, do you have the need? The need for speed? If so, then you’re not going to find a faster camera out there. The A9 costs $4,500 for the body alone. While that’s cheaper than the Canon 1DX or the Nikon D5, unless you really, really need to be able to shoot fast-moving objects, then you’re probably better off with one of Sony’s A7 series cameras (get the mark II versions). These are also full-frame, mirrorless cameras that take excellent pics, they just aren’t as fast. But if you’re a budding sports photographer and you aren’t already heavily invested in glass from another manufacturer, the Sony A9 is incredible in so many ways.
Steroid hormones and derivatives are labeled to high specific activities with activated tritium generated by microwave discharge of tritium gas. The steroid nucleus is not degraded by reactions with tritium; the hydroxyl and oxo groups at 3, 11, 17, and 20 positions of the steroid nucleus are not displaced by tritium but are oxidized or reduced to form the labeled by-products. Saturation of A ring occurs readily, but tritium addition to the isolated C C double bond occurs in the order of Δ 1 > Δ 4 > Δ 5 . Steroids with the 21-hydroxyl group are not tritiated. Despite the addition reaction, the final products from the unsaturated steroids may still contain significant amounts of the labeled parents. Specific activities of the labeled by-products steroids can approach 29 Ci/mM.
