La fluoresce\u00edna es un compuesto org\u00e1nico sint\u00e9tico que se presenta en forma de polvo de color naranja oscuro\/rojo y es ligeramente soluble en agua y alcohol. Se utiliza ampliamente como trazador fluorescente para muchas aplicaciones.<\/p>\n

La fluoresce\u00edna es un grupo fluorescente utilizado habitualmente en microscopios, l\u00e1seres de colorante como medio de ganancia, detecci\u00f3n forense y serol\u00f3gica de posibles manchas de sangre, y rastreo de colorantes. La longitud de onda m\u00e1xima de absorci\u00f3n de la fluoresce\u00edna es 494 nm, y la longitud de onda m\u00e1xima de emisi\u00f3n es 521 nm (en agua). Los principales derivados son el isotiocianato de fluoresce\u00edna (FITC) y la amida fosforada 6-FAM en la s\u00edntesis de oligonucle\u00f3tidos.<\/p>","protected":false},"featured_media":4154,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[22],"product_tag":[24],"class_list":{"0":"post-4099","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-daily-chemicals","7":"product_tag-daily-chemicals","9":"first","10":"instock","11":"shipping-taxable","12":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/chemneo.com\/es\/wp-json\/wp\/v2\/product\/4099","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/chemneo.com\/es\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/chemneo.com\/es\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/chemneo.com\/es\/wp-json\/wp\/v2\/comments?post=4099"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/chemneo.com\/es\/wp-json\/wp\/v2\/media\/4154"}],"wp:attachment":[{"href":"https:\/\/chemneo.com\/es\/wp-json\/wp\/v2\/media?parent=4099"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/chemneo.com\/es\/wp-json\/wp\/v2\/product_brand?post=4099"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/chemneo.com\/es\/wp-json\/wp\/v2\/product_cat?post=4099"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/chemneo.com\/es\/wp-json\/wp\/v2\/product_tag?post=4099"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
