Study type: Medical/biological study (experimental study)

A novel method for the study of fluorescent probes in biological material during exposure to microwave radiation med./bio.

Published in: J Biochem Biophys Methods 1981; 5 (3): 157-167
Journal partially peer-reviewed/peer-review process unclear

Aim of study (acc. to author)

To investigate the effect of 2450 MHz CW microwave irradiation on calcium binding to erythrocyte ghosts. For this approach the fluorescent probe ANS (1-anilino-8-naphthalene sulfonate) was used.

Main outcome of study (acc. to author)

Overall no effects were observed. Neither specific absorption rates of 10 and 200 mW/g nor calcium doses between 2.0 and 10.0 x10-4 M had any effect on binding of ANS to the erythrocyte ghosts or calcium binding, respectively. Also the intrermolecular distances between membrane bound ANS and intrinsic tryptophan residues were not altered.
