Published in: Radiat Res 1988; 114 (3): 500-514

Aim of study (acc. to author)

To investigate the phenomenon of protein shedding in human erythrocytes caused by mircowave irradiation.

Background/further details

Quantitative and qualitative protein determination was assessed by using different methods of high performance liquid chromatography (HPLC) and erythrocyte blood group antigen testing, respectively.

Main outcome of study (acc. to author)

Microwave exposure leads to an approximate twofold release of protein mass. The released proteins were characterized as hydrophobic, positive net charged, and nonpolar. The results of the blood group antigen testing support the idea that these proteins are loosely peripheral bound to the cell surface.
