Description
Xpress Capture Protein A/G Coated Microplates provide a solid-phase surface for capturing immunoglobulins through affinity interactions between immobilized Protein A/G and the Fc region of compatible antibodies. Fc-directed capture helps position the antigen-binding regions away from the plate surface so they remain available to bind target molecules in solution.
Protein A/G combines immunoglobulin-binding domains from Protein A and Protein G to provide broad IgG-binding capability across many species, classes, and subclasses. This combined binding profile can be useful when the species or subclass has limited affinity for Protein A or Protein G alone.
The plates are intended for research immunoassays in which an immobilized antibody captures a labeled or otherwise detectable antigen. Detection may be performed with enzyme-labeled, biotinylated, fluorescent, chemiluminescent, or comparable reagents.
