Abstract: A method to produce actively growing mycoplasma organisms in microcolonies and which have a high content of species specific membrane antigen, is disclosed. The specific membrane antigen can be used to detect specific antibodies against mycoplasma in a patient's serum samples. It can also be used to elicit antibody production in animals so that the specific membrane antigen of mycoplasma can be detected using animal antibody tracers, in the sputum of patients having a mycoplasma infection.

Abstract: A cytochemical agent and method for the detection and identification of estrogen or progesterone receptor cells in carcinomas of the breast is described, involving an estrogen-protein-fluorochrome conjugate or a progesterone-protein-fluorochrome agent which is applied to an excised unfixed frozen tissue section, which is then examined for the appearance of fluorescent dye staining of the cells therein, for evaluation of potential endocrine or hormone therapy of the patient. Additional cytochemical agents and methods for the detection of other types of hormone receptor cells in various kinds of cancerous tissue are also disclosed, using sex hormones and endochrine steroid components.
