Our lectin array service provides a high throughput platform for the rapid characterization of glycosylation in recombinant proteins, serum proteins, exosomes or ECM proteins
The technology utilizes a panel of nearly 50 different lectins as probes for testing the presence of a large number of biologically relevant glycan binding motifs and structural elements simultaneously on N- and O-glycans as well as glycolipids without requiring previous deglycosylation. We have over 15 years experience in lectin microarray development and analysis covering recombinant glycoproteins, serum glycoproteins, synthetic neoglycoproteins, cells, exosomes or extracellular matrix (ECM) proteins.
Over 48 highly purified lectins isolated from natural sources with well established glycan binding specificities are printed in 5 replicates alongside control samples (printing buffer containing BSA). We print our lectin microarrays on Premium Schott Nexterion 3D hydrogel glass slides with ultralow background and excellent protein stabilisation properties.
Please inquire for custom array development if you have larger sample numbers or are interested in a specific lectin panel.
Method Summary
Glycoanalysis is performed in triplicate.
Glycoproteins samples are fluoresecently labeled, incubated on the lectin array and the interactions quantified by fluorescence detection. Semiquantitative binding data is provided as histograms showing the corresponding lectin interaction profiles for each sample. Raw data (xlsx format) and a fluorescence image of the incubated lectin microarrays are also provided.
