Two novel IgG endopeptidases of Streptococcus equi.

Streptococcus equi ssp. equi causes strangles, a highly contagious and serious disease in the upper respiratory tract of horses. Streptococcus equi ssp.

Particulate platform for bioluminescent immunosensing.

The present study examines pyruvate kinase-conjugated antibodies for potential use in ELISA applications. The conjugates had an acceptable stability, and the coupling inflicted only minor impairment on the kinase activity. To mimic the setup of an immunoassay under development, a test antigen (BSA) was attached to polystyrene nanoparticles.
