一般說明
A Protein Conformational Array (PCA) in a sandwich ELISA format where the plate is coated with a panel of antibodies raised against peptides derived from the full length protein sequence of human GCSF. Taken individually, each of these antibodies is strongly antigenic to the peptide sequence that was used in its production. However, when these peptides are incorporated into a full length correctly folded protein, the antigenicity of many of them is masked by the three dimensional structure of the protein and a basal level of epitopes are detected by this assay. The result is a histogram which can be likened to a ‘fingerprint′ for correctly folded Filgrastim. For an Filgrastim Biosimilar, if the protein is correctly folded and modified, the ‘fingerprint′ will match that of Filgrastim. If it is not correctly folded, previously masked peptide sequences will be exposed and will be recognized by the antibody made to that exposed sequence. In this way, changes in the ‘fingerprint′ generated by the ELISA will point out differences between the Biosimilar and authentic Filgrastim.

Antibody arrays were developed to probe a monoclonal antibody's three-dimensional structure (3-D structure). Peptides with overlapping regions were designed to cover the whole mAb light chain and heavy chain, respectively, and used to generate polyclonal antibodies after the conjugation of

The elucidation of antibody higher order structure (HOS) is critical in therapeutic antibody development. Since HOS determines the protein bioactivity and chemo-physical properties, this knowledge can help to ensure that the safety and efficacy attributes are not compromised. Protein conformational
