A wide range of products—flexibility for your research

Invitrogen Surface-activated Dynabeads are available in different sizes, with a hydrophobic or hydrophilic nature, and with a variety of surface chemistries (see Table 1 below). To obtain the best possible results it is important to choose a size and surface of the Dynabeads suited for your application. The choice will depend on the nature of the ligand. In most applications several Dynabeads products can be used.


Antibodies or other ligands can be coupled onto the beads for affinity protein capture
