NOTE
-
The expression "involving", when used in relation to a material includes the testing for the material as well as employing the material as a determinant or reactant in a test for a different material.

In groups G01N 33/52 to G01N 33/96, in the absence of an indication to the contrary, an invention is also classified in the last appropriate place.

Documents relating to new peptides or new DNA or its corresponding mRNA, encoding for the peptides, and their use in measuring or testing processes are classified in subclass C07K or in group C12N 9/00 according to the peptides, with the appropriate indexing codes relating to their use in diagnostics.
