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 Ustekinumab. 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 only a limited number of the antibodies respond. The result is a histogram which can be likened to a ‘fingerprint′ for correctly folded Ustekinumab. For a Stelara Biosimilar, if the protein is correctly folded and glycosylated, the ‘fingerprint′ will match that of Ustekinumab. 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 Ustekinumab.

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
