restrict to techniques of labeling with isotopes (stable or radioactive): do not use for radioisotope tracer studies of "labeled" cells, microorganisms or chemicals ( = chemical NIM with no qualifiers), as Cr51-labeled erythrocytes = ERYTHROCYTES + CHROMIUM RADIOISOTOPES but not ISOTOPE LABELING
Scope Note
