G01N 33/50 - Definition
This group covers:
Chemical analysis of biological material, e.g. blood (in vitro), urine.
Testing involving biospecific ligand binding methods.
Use of compounds or compositions for colorimetric, spectrophotometric or fluorometric investigation, e.g. use of reagent paper.
Immunological testing, including immunoassay or materials therefor.
Relationship between large subject matter areas
New peptides or new DNA or its corresponding mRNA, encoding for the peptides, and their use in measuring or testing processes should be classified in subclass C07K or in group C12N 9/00 according to the peptides, together with the appropriate classification relating to their use in diagnostics.
