Protocol Outline
Dry the glass slide
Block array surfaces
Incubate samples (samples need to be biotinylated for the label-based approach)
For the the sandwich-based principle, incubate with a detection antibody cocktail
For the label-based principle, incubate the labeled-streptavidin.
Incubate with Cy3 Equivalent Dye-
Streptavidin
Disassemble the glass slide
Scan with a gene microarray laser scanner
Perform densitometry and analysis
Storage/Stability
Upon receipt, all components of the Raybiotech Lectin Array 95 kit should be stored at -20°C. Once thawed, the glass slide and Cy3 equivalent dye-conjugated Streptavidin should be kept at –20°C and all other components may be stored at 4°C. The entire kit should be used within 6 months of purchase.
Additional Application Information
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.
Product Feature

Low sample volume (10-100 µl per array)
Large dynamic range of detection
Compatible with most sample types
Test 12 samples on each slide
Suitable for high-throughput assays
Application 1 - Detection of Glycans on a Purified Protein
See Image/s
In this application, the RayBio Lectin Array 95 was used to detect specific glycosylations of purified Horseradish Peroxidase (HRP). Lectins BANLEC, BC2L-A, CALSEPA, GNA, HHA, NPA, PA-IIL, and PALa showed strong signals after incubation with 3.3 ug/mL Biotin-HRP followed by detection with streptavidin-fluorescence-dye (Figures A, B and C). The fluorescence signals from BANLEC, BC2L-A, CALSEPA, GNA, HHA, NPA, PA-IIL, and PALa were blocked in a concentration-dependent manner by HRP itself (Figures A and C), indicating that the signals were generated by lectin-HRP binding. These eight lectins are known to exhibit specific binding to mannose, which indicates that HRP contains mannose. After adding increasing amounts of mannose, the signals from BANLEC, BC2L-A, CALSEPA, GNA, HHA, NPA, PA-IIL, and PALa were reduced (Figures A and B).The reduction in signals from increasing concentrations of mannose confirms that HRP protein contains mannose in its glycocalyx. Additionally, the two lectins AAL and RS-FUC (fucose binding specificity) also showed strong interaction with HRP, which indicates the fucosylation of HRP. Overall, the results of the Lectin Array 95 were consistent with published literature regarding HRP glycosylation.
Application 2 - Profiling of a Serum Sample
See Image/s
Using the lectin 95 array, we can discover the different glycoprotein profiles of serum samples, cell lysates, or purified glycoproteins. The images above show the profiles of the glycans from different types of samples including human serum, recombinant glycoproteins human HE4 and AFP, mouse TFF2, purified human IgG, and bacterial DE3 cell lysates detected by Biotin labeling and fluorescent dye-streptavidin.
