ABSTRACT Mycoplasma species bovine group 7 bound plasminogen at the cell surface in a lysine-dependent manner. Cell-bound plasminogen was rapidly activated to plasmin by exogenous urokinase, and this activity was associated with plasminogen binding capacity. Binding assays using plasminogen modified with a trifunctional cross-linking agent revealed several binding proteins.

Identification of cellular phenotype by cell surface antigens in conjunction with ultrastructural analysis of cellular morphology can be a useful tool in the study of biologic processes as well as in diagnostic histopathology. In this abstract, we describe a simple pre-embedding, protein A-gold staining method which is designed for cell suspensions combining the handling convenience of slide-mounted cell monolayers and the ability to evaluate specimen staining specificity prior to EM embedding.

Number Of Cells

The proliferative reactivity of lymphocytes from rat donors maintained under germfree or conventional conditions was examined in mixed lymphocyte cultures stimulated with allogeneic and xenogeneic cell surface antigens. The results show (a) that lymphocytes from conventionally maintained rats are less reactive to human, hamster, guinea pig, and mouse cell surface antigens than to the major H alloantigens, and (b) that lymphocytes from germfree rats display no demonstrable reactivity to xenogeneic cells, but are quantitatively normal in their response to allogenic cells. The conclusion drawn from these observations is that the circulating lymphocyte pool of an individual consists of a greater proportion of cells reactive to H alloantigens of other members of the same species than to the xenogeneic cellular antigens of members of other species and that this large number of cells is not generated by a mechanism involving immunization to cross-reactive environmental antigens.
