Arsenic elevates the sister chromatid exchange (SCE) rate in human lymphocytes in vitro

Arsenic elevates the sister chromatid exchange (SCE) rate in human lymphocytes in vitro

F Zanzoni et al. Arch Dermatol Res. 1980.

Abstract

The number of sister chromatid exchanges (SCE) per metaphase was determined in normal human lymphocytes by the Hoechst-Giesmsa procedure. The addition of inorganic trivalent arsenic (Na2HAsO4) 10(-6) M and 2 x 10(-6) M induces a significant and dose-dependent increase of SCE. This phenomenon is as sensitive as the evidence of arsenic-induced chromosomal aberrations in vitro.
