In tube one, the blood cells were placed in a tube with the volume of stock mM NaCl was 1. In tube two, the blood cells were placed in a tube with the volume of stock mM NaCl was. In tube three, the blood cells were placed in a tube with no NaCl and 1. After the blood cells were placed in their tubes, the blood cells were swirled and were observed after one to five minutes. This lab included various experiments that demonstrated how renal system responses and reacts when subjects consuming different types of fluids. For the control subject, she ingested no fluid throughout entire lab which represented the conditions of normal fluid.
Radioimmunoassay: Principle, Uses, and limitations - Learn Microbiology Online
RIA or Radioimmunoassay is an in vitro assay that measures the presence of an antigen with very high sensitivity. Basically any biological substance for which a specific antibody exists can be measured, even in minute concentrations. RIA has been the first immunoassay technique developed to analyze nanomolar and picomolar concentrations of hormones in biological fluids. Radioimmunoassay RIA is a sensitive method for measuring very small amounts of a substance in the blood.
The scope of applicability of radioimmunoassay is rapidly expanding with the dawn of each day as RIA is being developed for newer pharmaceutical substances. It has attained wide recognition and application both in vitro and in vivo measurements of compounds of interest like insulin, gastrin, glucagon, and growth hormones on one hand ; whereas drugs like :. Morphine — Narcotic analgesic,.
