Antigen immobilisation for sensitive immunoassays

Invitrogen has launched the Dynabeads M-270 immunoassay (carboxyl) from Dynal, developed to provide precise immobilisation of antigens such as proteins, peptides, steroids and hormones for in vitro diagnostic (IVD) magnetic bead-based immunoassay applications.

The antigens are coupled directly or via a cross-linker to carboxylic acid groups on the new 2.8 micron Dynabeads.

The hydrophilic surface of the beads ensures low non-specific binding of serum proteins that would otherwise interfere with the assay. The beads disperse well, are easily handled in a wide variety of buffers and do not inhibit enzymatic activity. The Dynabeads M-270 immunoassay (carboxyl) can also be included directly in downstream analysis of the bead-bound target molecule.
