Percoll and Percoll Plus are manufactured by Cytiva. The Product Information Sheet for this product provides a basic protocol and references for common cell types. Additional references and mathematical models can be found on the Cytiva website.
Typically, references identify a specific density for each cell type or molecule of interest. Instructions for preparing a specific density are included in the product information sheet or a similar document on the Cytiva website. The references will mention the G force to be used, as it accurately defines the centrifuge conditions. If revolutions per minute (RPM) is stated, the radius of the centrifuge affects the outcome. Nomogram tables are available for converting G force to RPM. To find a nomogram table, search for "nomogram" in the document titled "Centrifugal Filters: Guide to Converting g-Force to RPM." Instructions for use are included to convert G force to the appropriate RPM setting for a specific centrifuge.

General description
Application
Features and Benefits
- La baja osmolalidad permite un ajuste preciso a las condiciones fisiológicas sin interferencias significativas del medio.
- Compatible con células y virus vivos y permite la separación y la recuperación de sistemas intactos, totalmente activos.
- Impermeable a las membranas biológicas lo que no provoca ningún cambio en la densidad de flotación de las partículas durante la centrifugación.
- La formación espontánea del gradiente durante la centrifugación permite mezclar grandes volúmenes de muestra en los tubos de centrífuga.
- La baja viscosidad provoca una rápida formación de gradientes y separación de partículas.
- La mayoría de las partículas biológicas que tienen valores de coeficiente de sedimentación superiores a 60S pueden aislarse satisfactoriamente en gradientes de Percoll.
