Knowledge Base: What is lectin microarray?
Advances in glycosylation profiling techniques have driven progression in the field of glycobiology. Lectins are a class of carbohydrate-binding proteins purified from plants or animals that can bind to different carbohydrate structural epitopes in a highly specific manner. Lectin array is a lectin-based glycan profiling technique to evaluate the entire feature of glycosylation of an intact biological sample. It is a sensitive, rapid, non-sample-destructive, and high-throughput profiling method directly applicable to glycans in native forms (e.g., on proteins, cells, and tissues). It is also in a simple assay format and requires only a small amount of a sample. Therefore, lectin array-based glycosylation profiling is one of the most widely used methods in glycobiology, especially favored by researchers who don’t have extensive experience in glycoscience.
Applications of Lectin Microarray
Knowledge Base: What are the workflow steps of a lectin microarray analysis?
Step 1: Ultra-high-quality glass slides with minimal autofluorescence are coated with our patented substrates to immobilize lectins to the surface.
Step 2: Individual lectins sourced from plants are covalently attached to the microarray substrates.
Step 3: After any additional reactive sites on the coating surface are blocked, the analysis samples are introduced to the array. After incubation, any unbound samples are washed away.
Step 4: Fluorescently labeled antibodies or streptavidin bind to the samples which are bound to lectins on the array, and provide a fluorescent signal read out by a microarray scanner.
Step 5: The lectin array data are analyzed by a software tool to determine the presence of specific types of glycans or glycan motifs.
