https://doi.org/10.1007/BFb0093653oying the double-isotope-derivative method for the assay of steroids in biological fluids. These difficulties have been experienced particularly during the assay for steroids which are present in very low concentration, e.g., testosterone and etiocholanolone.子女 发表于 2025-3-28 23:56:29
Formulation within a Classical Context Full use of a specific label is achieved when procedures are also available which permit specific degradation of products and ultimate recovery of the isotope in a degradation product that pinpoints the exact location of the tagged atom.简洁 发表于 2025-3-29 06:04:06

It was also hoped that as a result of determining the deuterium distribution in the molecule, some insight into the mechanism of exchange on this catalyst would be gained.表示向前 发表于 2025-3-29 14:04:58
Alexander von Eye,Wolfgang Wiedermanne of them than would be expected. This is due chiefly to difficulties in obtaining radioactive tracers in their proper chemical forms. Labeled compounds that can be purchased are generally expensive, are sometimes of questionable purity, and the time for delivery may be excessive.legitimate 发表于 2025-3-29 19:04:51

The advantages of the use of these biological methods for the synthesis of labeled compounds are obvious when one considers the difficulties involved in preparing a compound through a long series of organic reactions. In addition to the biological procedures which make use of平静生活 发表于 2025-3-29 23:46:34
The Cohomology of , as an FI-Module,ver with albumin appeared to be primarily of basic and theoretical interest, more recently it has assumed practical and clinical importance. This latter fact has come about because certain syndromes associated with low serum albumin and excessive loss of albumin into the gastrointestinal tract can oTHROB 发表于 2025-3-29 23:58:38
