Invitrogen Launches Antigen Immobilization Technology for Sensitive Immunoassays
Invitrogen Corporation has announced the launch of Dynabeads® M-270 Immunoassay (Carboxyl) from Dynal® – developed to provide immobilization 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. Dynabeads® M-270 Immunoassay (Carboxyl) can also be included directly in downstream analysis of the bead-bound target molecule.
