          Abstract

          La electroforesis unicelular es un ensayo muy sensible para detectar el daño en el ADN provocado por diferentes agentes físicos, químicos y biológicos. A pesar de que Artemia franciscana es un modelo experimental muy importante en diferentes áreas, en la literatura no se encuentran estudios en los que se lleve a cabo esa prueba de genotoxicidad con células de esta especie. El objetivo de este trabajo fue desarrollar el protocolo para obtener una suspensión celular de A. franciscana apropiada en calidad y cantidad para detectar posteriormente rompimientos sencillos en las cadenas de ADN mediante el ensayo cometa.

          Translated abstract

          Unicellular electrophoresis is a highly sensitive assay to detect DNA damage caused by various physical, chemical and biological agents. Despite Artemia franciscana is an important experimental model in different areas, there are no studies that refer to genotoxicity in Artemia through this assay. The aim of this study was to establish the protocol to obtain a cell suspension of A. franciscana appropriate in quality and quantity to assess single DNA strand breaks through the comet assay in the future studies.

          The single cell gel electrophoresis assay (comet assay): a European review.

          The single cell gel electrophoresis (SCGE) assay is a rapid, simple, visual and sensitive technique for measuring DNA breakage in individual mammalian cells. Here we review the development of the SCGE assay (with particular reference to the alkaline version), existing protocols for the detection and analysis of comets, the relevant underlying principles determining the behaviour of DNA, and the potential applications of the technique.

            The comet assay: a comprehensive review.

            The comet assay is a sensitive and rapid method for DNA strand break detection in individual cells. Its use has increased significantly in the past few years. This paper is a review of the studies published to date that have made use of the comet assay. The principles of strand break detection using both the alkaline and neutral versions of the technique are discussed, and a basic methodology with currently used variations is presented. Applications in different fields are reviewed and possible future directions of the technique are briefly explored.

              Use of the genus Artemia in ecotoxicity testing.

              Information related to varied uses of several species of the genus Artemia (commonly known as brine shrimp), is dispersed among literature from several scientific areas, such as Ecology, Physiology, Ecotoxicology, Aquaculture and Genetics. The present paper reviews information related to Artemia that may be considered relevant for ecotoxicity testing. Integration of different areas of scientific knowledge concerning biology, life cycle and environmental needs of Artemia is of crucial importance when considering the interpretation of results drawn from tests involving this genus. Furthermore, this paper provides suggestions to overcome problems related to toxicity assessment with the use of Artemia as test organism in bioassays, under the scope of estuarine, marine and hypersaline environments. Aspects related to variability in results, adoptable toxicity end-points, culture conditions, characteristics of species and strains, influence of geographical origins over physiological features and responses to exposure to chemical agents are considered.
