Introduction
The Raybiotech lectin array uses standard glass slides each spotted with 14 wells of identical lectin arrays. Each lectin, together with the positive controls is arrayed in duplicate. The slides each come with a 16-well removable gasket which allows for the process of 14 samples using one slide. Four slide slides can be nested into a tray, which matches a standard microplate and allows for automated robotic high throughput process of 56 arrays simultaneously. The RayBiotech lectin array provides a powerful new tool for glycosylation determination, drug discovery and biomarker development; all with limited samples volumes required.
Product Feature
- High sensitivity and specificity
- Low sample volume (10-100 µl per array)
- Large dynamic range of detection
- Compatible with most sample types
- Test 14 samples on each slide
- Suitable for high-throughput assays

Application Data/Notes
Application 1 Detection of Glycans on HRP
See Image/sAfter biotinylation of HRP we can determine what kind of glycans are conjugated to HRP by using the RayBiotech lectin array. Lectins, GNA, HHA, NPA showed strong signals after incubation with 0.33 ug/mL Biotin-HRP followed detection by streptavidin-fluorescence-dye (Figure A, B and C). The fluorescence signals from GNA, HHA and NPA can be blocked in a concentration depend manner by HRP itself (Figure A and B), which means that these fluorescence signals were generated based on the binding between HRP and the three lectins. As we know, GNA, HHA and NPA lectins specifically bind to mannose which indicates that HRP contains mannose. By adding increasing amount of mannose, the signal from GNA, HHA and NPA can be reduced (Figure A and C). The reduction signals from increasing concentrations of mannose confirms that HRP protein contains mannose in its glycocalyx. Lectin VVA binds to the streptavidin-fluorescence dye.
Application 2 Profile of Serum Samples
See Image/sUsing the lectin array, we can discover the different glycoprotein profiles of the serum samples or cell lysates from patient cohorts versus a control group. Below images showed the profiles of the glycans from serum samples detected by Biotin-anti-human IgG and Fluorescence dye-streptavidin.
Suggested Applications
- Identify and profile the glycans in their samples
- Determine whether their biomarker of interest has glycan moieties
- Find specific glycan binding ligands in biological samples
Other Applications
Quantitative analysis of lectin-glycoprotein interactions. Example: a concentration series of glycoproteins detected with the lectin array could reveal concentration dependent effects of lectin-glycan binding.Determine the profile of bacterial cell-surface glycans. Example: Cell lysate from bacteria can be Biotinylated and hybridized to the lectin array. Analysis of the binding pattern and correlation with the known carbohydrate-binding specificities of the lectins can determine the glycans on the cell membrane.
