Glycobiology Arrays

Empowering Your Glycomics

RayBio® Glycobiology Arrays are a versatile and innovative series of products designed to detect glycosylation. Glycosylation plays an important role in a wide variety of disease processes including tumor cell metastasis, inflammation and bacterial pathogenesis. The RayBio® Glycobiology Arrays are available in three different formats for detection of glycans or glycan-protein interactions. All 3 formats feature glass slide supports with fluorescent detection.

Glycan Arrays

Finding Glycan binding partners, determining mechanisms of pathogen binding, autoantibody testing, microbiological interactions

  • Immobilized Sugar Moieties (Glycans)
  • 100 or 300 targets
Glycan Array Detection

Glycome Arrays

Determine glycoprotein profile of a  sample

  • Immobilized Antibodies
  • Human, mouse and rat
  • up to 1000 targets

Glycome Array Detection

Lectin Arrays

Determine the sample glycan profile, determine changes in glycan moieties, find novel glycan ligands

  • Immobilized Lectins
  • 70 or 95 targets

Lectin Array Detection

Antibody Arrays

More Data, Less Sample!

Antibody arrays are a multiplex assay that simultaneously measures the expression of multiple proteins. They allow a much broader view of protein activity than can be obtained with single-target ELISAs and western blots. Several platforms (planar vs. bead-based) and techniques for visualizing protein expression (chemiluminescent, fluorescent, etc.) can be used depending on the sample or analyte requirements, which allows for a more comprehensive analysis of biological responses and functions and identification of key factors or disease mechanisms.

Protein Arrays

RayBio® Protein Microarrays

RayBio® Protein Arrays are a versatile and innovative series of products featuring immobilized proteins spotted onto a glass slide support to profile serological (auto)antibodies as well as study protein interactions with other proteins, peptides, DNA, and drugs.

Protein arrays are semi-quantitative and allow a much broader view of protein activity than a traditional ELISA. RayBio arrays come in smaller, research specific panels as well as broad screening panels. Read more
