Descripción

Calcein UltraBlue™ AM, sonda fluorescente

Calcein UltraBlue™ AM es una versión permeable a las células de Calcein UltraBlue™. Al ingresar a las células vivas, Calcein UltraBlue™ AM, débilmente fluorescente, se hidroliza en Calcein UltraBlue™, que tiene máximos de excitación/emisión similares a los de Calcein Blue, DAPI, Hoechst y AMCA.

Esta excepcional separación espectral de los típicos fluoróforos verdes y rojos (como FITC, TMR y Texas Red) proporciona opciones adicionales para experimentos de multiplexación. Calcein UltraBlue™ tiene propiedades espectrales similares a las de Calcein Blue.

Sin embargo, en comparación con Calcein Blue, Calcein UltraBlue™ tiene una mayor fotoestabilidad y una mayor intensidad de fluorescencia a pH fisiológico, lo que la convierte en una sonda fluorescente más robusta que Calcein Blue.

Nombre en Ingles: Calcein UltraBlue™ AM
