Description

These plates are uniformly and stably coated with one of four popular immunoglobilin-binding proteins (Protein A, Protein G, Protein A/G, or Protein L). They enable antibodies, or pre-established antibody-antigen complexes, to be captured to wells of the polystyrene plate for subsequent detection in plate readers. The strategy is useful for a variety of assay situations, but it is generally not suitable for sandwich-type ELISA.

Thermo Scientific Pierce Protein Coated Plates provide an alternative to direct, passive adsorption methods for immobilizing antibodies for ELISA and other plate-based assay techniques.

Highlights
• Retain antibody activity, which can be lost when antibodies are immobilized by passive adsorption
• Orient antibodies for maximum antigen-binding capacity
• Immobilize antibodies for plate assays without prior purification
• Ensure minimal variation (<5% well-to-well) from consistent coating
• Reduce nonspecific binding because plates are pre-blocked with SuperBlock Blocking Buffer
• Bind 2 to 5 pmol of antibody per well (based on tests with rabbit IgG)

Protein A/G Coated Plates
• Fusion protein containing four antibody-binding sites from Protein A and two from Protein G
• Binds to most IgG species because it combines the specificities of Protein A and Protein G
• Binds to Fc region of antibodies, ensuring optimal orientation
• Binds well using a wide range of pH

Protein A Coated Plates
• Binds strongly to IgG from human, rabbit, guinea pig, pig, dog, and rhesus monkey
• Binds strongly to mouse IgG2a, IgG2b and IgG3
• Binds to Fc region of antibodies for optimal orientation

Protein G Coated Plates
• Binds strongly to IgG from many species including human, mouse, rabbit, sheep and goat
• Binds only to IgG—no cross-reactivity with other antibody classes
• Binds to Fc region of antibodies for optimal orientation

Protein L Coated Plates
• Binds to all classes of immunoglobulins (IgG, IgM, IgA, IgE and IgD)
• Binds to the VL region of kappa light chains (human I, III, IV and Mouse I) without interfering with antigen-binding sites
• Binds to Fab fragments and ScFv
• Does not bind bovine, goat or sheep immunoglobulin
• Binds weakly to rabbit immunoglobulin
• Pre-blocked to reduce nonspecific binding
