Provided are peptide analogues of PA-IL and compositions containing them. The PA-IL peptide analogues have altered carbohydrate binding specificity relative to a PA-IL of SEQ ID NO:1, and thus the analogues contain amino acid substitutions in SEQ ID NO:1. The substitutions can be at positions 50, 52 and 53 of SEQ ID NO:1 and can include combinations of amino acid substitutions at those positions. Also included are methods for detecting changes in the glycosylation of carbohydrates and for separating biomolecules which contain glycoproteins or glycoconjugates. |
