    Radioimmunoassay determination of plasma progesterone in the cow without chromatographic purification was developed. The level ranged from 0.6 ng/ml during estrus to 6.4 ng/ml during the luteal phase. The progesterone level declined rapidly 48 to 72 h before estrus beginning.

    Western Blotting

    Western blotting is an analytical technique for protein identification. It has various applications in immunology and medicine, including detecting diseases like bovine spongiform encephalopathy, mad cow disease, and human and feline immunodeficiency virus from biological samples.
    The technique begins with separating proteins from the sample using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), followed by protein transfer, immunoblotting, and finally, protein detection.
