XRAY SCATTERING FROM SERUM TRANSFERRIN

我们想用我们的超低温XMCD装置来 研究复杂生物的磁/电性质 样本。虽然这项技术相对较新，但我们已经 得到的数据表明实验具有很强的可行性。 有了我们的仪器，我们可以到达高达6特斯拉的磁场，用一个 温度在0.5K左右，或者我们可以使用我们新的快速扫描磁铁 它可以高达2特斯拉，不到130MK。使用 Beamline 5 EPU，我们取得了很好的成绩，希望 进一步推进这项工作。由于许多复杂的金属蛋白参与了 重要的生物氧化还原反应，对它们的磁性和 电子性质对于完全理解电子结构很重要 酶功能。

We would like to use our ultra-low temperature XMCD apparatus to examine the magnetic/electronic properties of complex biological samples. Although this technique is relatively new, we have already obtained data which shows the strong feasibility of the experiments. With our apparatus, we can reach fields as high as 6 Tesla, with a temperature of around .5K, or we can use our new rapid-sweep magnet which can go as high as 2 Tesla, with less than 130 mK. Using the beamline 5 EPU, we have obtained excellent results and would like to further that work. Since many complex metalloproteins are involved in important biological redox reactions, knowledge of their magnetic and electronic properties is important for a complete understanding of the enzymatic function.
