Phosphor 31p
WebPhosphorus-33 can be used to label nucleotides. It is less energetic than 32P, giving a better resolution. A disadvantage is its higher cost compared to 32P, as most of the bombarded 31P will have acquired only one neutron, while only some will have acquired two or more. Its maximum specific activity is 5118 Ci/mol. WebPhosphorus-31 Magnetic Resonance Spectroscopy. 31P MRS has been used to study a wide range of tissues such as muscle, heart, liver, and kidney in various physiological …

WebDecoupling 31P from 1H on the UI400 or U500 is easily accomplished with the standard QUAD probe. This handout outlines a procedure to acquire 1H{31P} spectra, where the phosphorus decoupling can be selective or non-selective. If you want to run this experiment on the U400 or VXR500 a cabling change is required. http://wanbin.sjtu.edu.cn/html/free%20resourse/31P%20NMR%20Chemical%20Shift%20of%20P(III)%20Compounds.pdf
