Lab on a Bead, Sweden

Lab on a Bead is a Swedish Biotech company that can provide the next generation high capacity magnetic separation platform for purification of biomolecules. The LOABeads magnetic beads combine the high binding capacity of agarose with fast magnetic separation. LOABeads are a flexible alternative for any bioseparation application, from microliter scale to liter scale.

Advantages of LOABeads :
  • Superior Binding Capacity :
    The high surface area of porous magnetic agarose beads results in high binding capacities.
  • Fast Magnetic Separation :
    The LOABeads beads show excellent super-paramagnetic behavior and are strongly attracted to external magnets which enables separation within seconds.
  • High Specificity :
    The hydrophilicity of the agarose offers minimal unspecific binding resulting in highly specific purifications.

LOABeadsTM Protein A :

These are intended for purification of antibodies from serum and ascites fluid samples, IgG serum depletion and immunoprecipitation. Combined with LOABeads MagSep separators, purification can be performed in standard 15 and 50ml centrifuge tubes, as well as 500ml bottles.

LOABeadsTM MabBind A :

These are magnetic agarose beads coupled with protein A optimized for efficient purification of IgG from cell cultures. The high specificity and high capacity of LOABeads MabBind A ensures that a very pure antibody is obtained with a high yield, even when antibody capture is performed directly in the cell culture medium.

LOABeads MabBind A are ideal to use in many applications of magnetic bead affinity chromatography (MBAC). For example in lab-scale purification of antibodies to be used in R&D and diagnostics and for characterizations of candidate biopharmaceutical IgG antibodies.
