MagSi-STA beads are magnetic silica beads coated with Streptavidin. 

The beads can be used in numerous biological and biochemical applications based on the very strong Streptavidin-Biotin bonding. Silica beads coated with Streptavidin can be used to isolate biotinylated proteins or other biotinylated molecules out of different media. It's easy to bind a biotinylated antibody to the MagSi-STA bead to isolate a specific target protein out of a cell lysate.

MagSi-S-Tools are particles for research & developmental use. MagnaMedics has more than 10 different coatings available for further bio-conjugations. Most common surface modifications for kit and application developmentare available.

In the past decades genomics has been developed and segregated to a) high throughput applications like blood and food diagnostics, b) very complex assays like for epigenetics analysis or c) highly reliable assays needed for forensics and of course d) highly economical applications.

All those different applications, interests and needs can not be matched with one single method nor with one single magnetic bead. High throughput applications supported by robotic liquid handling stations typically need magnetic beads with strong magnetic response whereas highly complex, manual DNA extraction applications needs magnetic beads with highest DNA capture, DNA selectivity and lowest unspecific binding.

For this purpose MagnaMedics has developed different types of magnetic beads specifically tailored to your needs. This paper should guide you through our MagSi magnetic particle portfolio specifically designed for the different DNA extraction methods and applications.

Isolation, separation and purification of proteins and peptides, as well as of other specific molecules, is commonly used in biotechnology research and production. New separation techniques, capable of treating dilute solutions or solutions containing only minute amounts of target molecules in the presence of vast amounts of accompanying compounds in both small and large-scale processes, even in the presence of particulate matter, are necessary.

A wide variety of techniques are used today involving a variety of chromatography, electrophoresis, ultrafiltration, precipitation and other procedures, whereof affinity chromatography being one of the most important techniques. However, these basic techniques have severe disadvantages over the use of magnetic nanoparticle solutions as provided by MagnaMedics Diagnostics with its patented product portfolio.
