Abstract:(1) The properties of the 5 cardiac antigens in human heart which cross-react with rabbit anti-rabbit heart auto-antibodies were studied, and compared to the rabbit heart auto-antigens analyzed previously. They were found to be similar in many respects. All were rendered undetectable by proteinases, but were unaffected by ribonuclease or desoxyribonuclease; they were salted out by exposure to similar concentrations of ammonium sulfate or potassium phosphate; they were variably labile to heat or pH extremes; an… Show more
