MagSi-proteomics

MagSi-proteomics beads are magnetic silica beads. The surface of the beads has been modified with C4, C8 and C18 alkyl groups typical for reversed phase applications.

 

The MagSi proteomics C18 beads are an ideal tool for the purification, concentration and desalting of peptides and protein digests. Compared to other C18 filled pipette or column tools desalting using MagSi proteomics C18 results in best quality MALDI ToF spectra at reasonable price. A typical protein tryptic digest of up to 1 nmol in total can now be desalted at prices below 1 EUR without time consuming, home brew column filling.

 

MagSi C8 beads represent an intermediate hydrophobicity (less hydrophobic than C18 and more hydrophobic than C4 beads) and are suitable for sample preparation in context to proteomic profiling and biomarker research. The relatively low hydrophobicity of the C4 beads allows the purification and fractionation of larger biomolecules like proteins.

So MagSi proteomics gives you the flexibility to desalt and prefractionate your sample ranging from small peptides to large proteins with top quality at reasonable price.
