  • Safety stanchion for fall protection system
    Patent number: 5307897
    Abstract: A safety stanchion is adapted for mounting to a structural I-beam to tie off workers. The safety stanchion includes a post which extends at an oblique angle to the base. The base is secured to the I-beam by means of a ratchet lock mechanism which hooks around the I-beam and a pair of bolts which lock against the underside of the I-beam. The stanchion provides a fixed mounting point for a fall protection system for workers with integral strength to accept stresses caused by falling objects and/or persons.

  • Double antibody immunoassays of enzymes such as prostatic acid phosphatase
    Patent number: 4510239
    Abstract: A method, kit and a solution for assaying enzyme, such as prostate acid phosphatase (PAP), in a sample. The sample is contacted with a first antibody (Ab.sub.1) against the enzyme and incubated. The resulting Ab.sub.1 -enzyme complex is contacted with a second antibody (Ab.sub.2) specific for Ab.sub.1. The resulting Ab.sub.2 -Ab.sub.1 -enzyme complex precipitates out of the medium. The precipitated complex is separated and solubilized with a pH controlled solution of gamma globulin. The resulting solution is then assayed for enzyme activity.
