Purificación en un solo paso de la vacuna viva atenuada contra el virus de la rabia
Purificación en un paso de la vacuna viva atenuada contra el virus de la rabia La rabia es una enfermedad vírica prevenible que se transmite con mayor frecuencia a través de la mordedura de un animal rabioso. El virus de la rabia infecta el sistema nervioso central de los mamíferos, causando finalmente la enfermedad en el cerebro y la muerte (CDC). En hasta 99% de los casos, los perros domésticos son los responsables de la rabia

Fases de intercambio iónico para la selectividad en cromatografía líquida
Ion-exchange Phases For Liquid Chromatography Selectivity Ion-exchange phases separate solutes on the basis of differences in ionic charge. Retention in ion-exchange chromatography is determined by the pH of the eluent, the nature and ionic strength of the buffer and temperature. Column efficiencies are lower than in reversed-phase HPLC. Eluents are normally aqueous but can contain

Breve introducción a la cromatografía líquida
Brief Introduction of Liquid Chromatography The history of Liquid Chromatography (LC) began in the early 20th century. In 1906, a Russian botanist Mikhail Tswett invented LC in order to separate various plant pigments. He injected the plant extract and petroleum ether through a glass column packed with calcium carbonate. Since this was done on a
