Lectin from Ulex europaeus-ATTO 594 conjugate

Ulex europaeus lectin (UEA) conjugated to ATTO 594 provides a fluorescent, carbohydrate-binding labeling reagent for visualization of fucose-containing glycans. This conjugate couples a well-established lectin specificity with a bright red/orange-emitting dye, enabling robust staining workflows in glycomics-oriented cell biology and microscopy studies. The ATTO 594 fluorophore supports fluorescence imaging readouts where lectin-based recognition of target glycans is used to map surface and extracellular carbohydrate patterns.

1. Glycan Binding Microscopy

Lectin from Ulex europaeus-ATTO 594 conjugate is widely used by cell biologists and glycobiology researchers to visualize fucosylated glycan epitopes on cell surfaces and in extracellular matrices. In fluorescence microscopy workflows, the lectin component guides localization to fucose-containing carbohydrate motifs, while ATTO 594 provides a red/orange channel for multi-color imaging alongside common green and far-red labels. This reagent is frequently applied to compare glycosylation phenotypes across cell lines, to assess changes in glycan presentation after perturbations, and to support qualitative mapping of lectin-reactive glycans in fixed-cell experiments.

2. Flow Cytometry Lectin Staining

Lectin from Ulex europaeus-ATTO 594 conjugate supports flow cytometry-based quantification of lectin-reactive fucosylated glycans on heterogeneous cell populations. Researchers use this conjugate as a fluorescent lectin probe to generate cell-associated fluorescence distributions that reflect relative abundance of UEA-binding carbohydrate epitopes. The ATTO 594 signal is particularly useful for gating and comparative analysis in multi-parameter panels where a red/orange excitation-emission window is advantageous, including studies of glycosylation shifts during differentiation, receptor/ligand biology, or glycan remodeling experiments.

3. Tissue And Fixed Sample Labeling

Lectin from Ulex europaeus-ATTO 594 conjugate is commonly incorporated into histology- and microscopy-style staining workflows to label fucosylated glycans in fixed tissue sections and permeabilized samples. In these applications, the lectin's carbohydrate recognition enables visualization of glycan patterns in situ, while ATTO 594 facilitates consistent fluorescence readout during imaging and downstream analysis. This approach is used by pathology-adjacent research groups and biomarker-focused labs to examine spatial glycosylation differences across sample regions and experimental conditions, supporting qualitative comparisons of lectin-reactive structures within complex biological matrices.

4. Glycoprotein And Surface Profiling

Lectin from Ulex europaeus-ATTO 594 conjugate is applied in glycoprotein profiling workflows where fluorescent lectin binding is used to assess fucosylated glycan presence on purified proteins, membrane preparations, or engineered biomaterials. Researchers often use the conjugate to screen or validate glycan display on surface-modified constructs, including cell-mimetic coatings and biomaterial surfaces designed to present specific carbohydrate motifs. The fluorescent labeling format enables straightforward readout in imaging and plate-based fluorescence assays, supporting confirmation of lectin-accessible glycan presentation without requiring direct chemical tagging of the target biomolecules.
