Comparative analysis of binding of native Nictaba and recombinant Nictaba proteins purified from Pichia on the glycan array. Different panels show interaction of a, native Nictaba (150 μg/ml, v4.0): b, Nictaba mutant 1 (100 μg/ml, v3.0); c, recombinant Nictaba (210 μg/ml, v4.0): and d, Nictaba mutant 3 (200 μg/ml v4.1). The complete primary data set for each protein is available on the website of the Consortium for Functional Glycomics (www.functionalglycomics.org)
