CAS 67-42-5: EGTA
Descripción:
EGTA, o ácido etilenoglicol tetraacético, es un agente quelante comúnmente utilizado en bioquímica y biología molecular. Tiene la capacidad de unir iones metálicos divalentes, como el calcio y el magnesio, lo que lo hace particularmente útil en diversas aplicaciones experimentales, incluyendo ensayos enzimáticos y purificación de proteínas. EGTA es un sólido cristalino incoloro que es soluble en agua, y su estructura presenta cuatro grupos de ácido acético unidos a una columna vertebral de etilenglicol, lo que le permite formar complejos estables con iones metálicos. El pH de sus soluciones puede afectar significativamente su capacidad quelante, con un rendimiento óptimo que se observa típicamente en condiciones neutras a ligeramente alcalinas. Debido a su fuerte afinidad por los iones de calcio, EGTA se emplea a menudo en estudios que involucran señalización de calcio y procesos celulares. Además, es importante manejar EGTA con cuidado, ya que puede interferir con ciertas reacciones bioquímicas al secuestrar iones metálicos esenciales. En general, EGTA es una herramienta versátil en la investigación, proporcionando información crítica sobre las interacciones de iones metálicos en sistemas biológicos.
