MagSi Magnetic Beads for DNA Purification

Achieve efficient biomagnetic separation

Magnetic beads coupled to specific ligands are a powerful tool used in a variety of research applications. Different compositions and sizes of the DNA extraction beads makes each one uniquely suited for a specific purpose.

AMSBIO supplies an extensive range of magnetic bead products for protein applications including sample preparation for protein and peptide analysis and beads for immunoprecipitation and IgG purification.

MagSi Proteomics

MagSi-proteomics beads are magnetic silica beads coated with C4, C8 or C18 alkyl groups, providing a reversed phase (RP) surface chemistry. These beads are an ideal tool for protein and peptide sample concentration, desalting and fractionation, and reduce sample complexity. The different versions of MagSi-proteomics beads vary in hydrophobicity making them ideally suited for unique applications:

C4

Relatively low hydrophobicity allows for the purification and fractionation of larger biomolecules such as proteins

C8

Intermediate hydrophobicity, suitable for sample preparation of peptides and small proteins for proteomic profiling and biomarker research

C18

Ideal for the purification, concentration and desalting of low molecular weight peptides and protein digests

MagSi-WCX and MagSi-WAX

Magnetic silica particles with weak cation exchange surface (WCX) or anion exchange surface (WAX) are ideal for the reduction of protein or peptide complexity. Applications include sample preparation and pre-fractionation prior to mass spectrometry or SDS-PAGE analysis, biomarker analysis and serum/plasma profiling.

MagSi-protein A/protein G

Magnetic silica particles with high quality recombinant Protein A or Protein G covalently bound to the particle surface.

Immunoprecipitation & IgG Purification

Protein A and Protein G bind to Fc regions of immunoglobulins. After binding to Protein A or G-coated magnetic beads, immobilized immunoglobulins can be used for immunoprecipitation of various biomolecules, or can be eluted in a native or denatured state. The magnetic particles with a mean size of 600 nm or 1.0 µm are best used for IgG purification and immunoprecipitation. The particles with a mean size of 3.0 µm are especially suitable for cell capture applications.
