The invention provides methods for preparing a peptide as an immunogen to generate an antibody specific for the deglycosylated form of a glycopolypeptide by preparing a peptide that includes an N-linked glycosylation site of said glycopolypeptide and identifying a peptide sequence that includes said glycosylated site and preparing said peptide wherein N of said site is converted to D.

Methods for characterizing glycoproteins and generating antibodies for same

The invention provides methods for preparing a peptide useful in generating an antibody specific for the glycosylated form of a glycopolypeptide wherein the glycosylated portion is isolated and a peptide corresponding to amino acids adjacent to a glycosylated N-linked glycosylation site is prepared.

The invention provides methods for generating an antibody specific for the deglycosylated form of a glycopolypeptide using a peptide corresponding to an N-linked glycosylation site of a glycopolypeptide. The invention additionally provides methods for generating an antibody specific for a glycopolypeptide using a peptide corresponding to amino acids adjacent to an authentic N-linked glycosylation site.
