Los colorantes iFluor® 514 con características espectrales especiales los convierten en una excelente alternativa al colorante de etiquetado Alexa Fluor® 514
Descripción
Los tintes iFluor® de AAT Bioquest están optimizados para marcar proteínas, en particular anticuerpos. Estos tintes son brillantes, fotoestables y tienen un enfriamiento mínimo de las proteínas. Pueden excitarse bien con las principales líneas láser de los instrumentos de fluorescencia (p. ej., 350, 405, 488, 555 y 633 nm).
Los colorantes iFluor® 514 tienen un máximo de excitación y emisión de fluorescencia de ~510 nm y ~527 nm respectivamente. Estas características espectrales los convierten en una excelente alternativa al colorante de etiquetado Alexa Fluor® 514 (Alexa Fluor® es la marca comercial de Invitrogen). iFluor® 514 SE es razonablemente estable y muestra buena reactividad y selectividad con los grupos amino de proteínas.
