✦ Synopsis

The Fourier transform Raman spectra of resins from several American Indian artefacts dating from 3000 yr BP were analysed and compared with samples of ancient and contemporary resins. The application of the technique to the non-destructive identiÐcation of materials of archaeological signiÐcance and their attribution is demonstrated. Molecular vibrational spectroscopic assignments, particularly of bands observed in the 1500-1750 cm~1 region, are useful as a source of identiÐcation of di †erences between natural resins and for evidence of degradation under sample interment conditions.

## Abstract Troponin C (TnC) is the Ca^2+^‐binding regulatory protein of the troponin complex in muscle tissue. Vertebrate fast skeletal muscle TnCs bind four Ca^2+^, while Akazara scallop (Chlamys nipponensis akazara) striated adductor muscle TnC binds only one Ca^2+^ at site IV, because all the o
