Method for assaying antigen related to disorders caused by mental stress

Novel foam proteins, monoclonal antibodies specifically recognizing said proteins, a method for determining foam protein contents in beer samples by an immunoassay using said monoclonal antibodies, a method for determining head retention and head retention stability of beer, as well as a method for evaluating raw materials of beer and stabilizers for beer are disclosed. The novel foam proteins crucial for head retention of beer have molecular weights of about 40000 to about 48000 as determined by Western blot analysis.

Foam proteins and use thereof

The present invention provides monoclonal antibodies that specifically recognize a specific structural portion of cardiac glycoside. The monoclonal antibodies of the present invention recognize an integrated structure in the steroid structure of cardiac glycoside or its aglycon comprising: a D-ring bonded in the cis-configuration with respect a C-ring; a methyl group bonded in the .beta.-configuration at the C13 position; a hydroxyl group bonded in the .beta.-configuration at the C14 position; and, an .alpha., .beta.-unsaturated lactone group bonded in the .beta.-configuration at the C17 position. This structure is common to cardiac glycoside substances that inhibit potassium ion concentration antagonist type Na.sup.+,K.sup.+ -ATPase.

Monoclonal antibody against cardiac glycoside and utilization thereof

A preparation of stabilized physiologically active substance which is produced by incorporating a physically and chemically modified gelatin in a physiologically active substance made of basic protein or polypeptide, such as interferons, specially gamma-interferon.
