Radioiodination with rz51 has emerged as the method of choice for labeling protein to high specific radioactivity. A number of procedures have been developed to iodinate proteins under mild conditions and with reproducible results (l-7). Of these techniques, none is suitable for the iodination of proteins having thiol groups. Exposure to the oxidants Nchloro-p-toluene sulfonamide (chloramine-T)...
A one-step synthesis of a cortisol derivative for radioiodination is presented. The radioimmunoassay for cortisol using the bridge heterologous 125I-labeled antigen was more sensitive than that using a bridge homologous antigen. Cortisol levels in saliva and serum were easily determined by direct radioimmunoassay with the proposed 125I-labeled antigen.
Bovine serum albumin is a model protein, which has been conventionally used as protein standard and in many areas of biochemistry, pharmacology and medicine. Radioiodination procedure for bovine serum albumin employing chloramine-T as an oxidant with slight modification was evaluated critically to establish the optimal conditions for the preparation of radiolabeled tracer ((125)I-BSA) with requ...
