Today, the study of the biological effects of non-ionizing electromagnetic waves (EMFs) (RF) is one of the most important subjects of theoretical and experimental studies. The purpose of this study was to evaluate the biological effects of human recombinant growth hormone (rhGH) Exposed to electromagnetic waves with a frequency of 940 MHz.Results of protein construction studies using dichroism (CD) circular experiments showed a destructive effect on the second building of the protein.In addition, the protein under the waves increases the fluorescence emission relative to the hormone Human recombinant growth is normal, which is possible Related to the development of protein building and the formation of abnormal collisions in protein and structural transformation.The results of dynamic light scattering (DLS) and Zeta potential test indicate that RF-EMFs have led to an increase in superficial load and rhGH size. Our results show that 940 MHz electromagnetic waves can alter the recombinant human growth hormone protein structure.
