Stain77, nuevo agente de contraste en Microscop\u00eda Electr\u00f3nica.
\nStain77 es un agente de contraste doblemente eficaz<\/strong> en secciones ultrafinas y en la tinci\u00f3n negativa de part\u00edculas aisladas en microscop\u00eda electr\u00f3nica.<\/p>\n

\"Stain77<\/a>Como Uranyless, requiere el contacto durante un minuto con las secciones ultrathins sobre una rejilla, luego un simple escurrido sobre papel de filtro seguido de un segundo contacto sobre una gota de citrato de plomo durante 20 a 30 segundos finalizado por un breve lavado con agua destilada.<\/p>\n

Proporciona un contraste muy suave y resalta perfectamente los distintos org\u00e1nulos celulares. Combinado con un tratamiento posterior con citrato de plomo, es posible delimitar compartimentos celulares marcando perfectamente las cito-membranas.<\/p>\n

\"\"<\/a> \"\"<\/a>\"\"<\/a>La toxicidad es casi nula<\/strong> y la coloraci\u00f3n puede hacerse en el borde del banco, es una sal de Litio asociada a una muy baja concentraci\u00f3n de Tungsteno, su pH es cercano a 7.<\/p>\n

Es f\u00e1cil de aplicar y estable en el tiempo. Puede utilizarse como alternativa al UranyLess acuoso cuando este \u00faltimo no sea concluyente para su Aplicaci\u00f3n.<\/p>\n

Seguimos desarrollando nuevos contrastantes porque, al no existir un fijador universal, siempre se puede mejorar el contraste para resaltar mejor todas las microestructuras celulares en diferentes<\/p>\n","protected":false},"excerpt":{"rendered":"
