VeraCode Carboxyl Bead Sets

VeraCode Carboxyl Bead Sets provide highly efficient tools for custom multiplexed protein-based assay development. Due to a carboxylated surface chemistry, the cylindrical glass VeraCode Carboxyl beads enable the immobilization of specific capture antibodies and covalent attachment of proteins, peptides, nucleic acids, and other ligands, facilitating the development of standard "sandwich" immunoassays. The 48 unique Carboxyl bead types can be pooled in varying combinations.

VeraCode Carboxyl Beads are highly stable and demonstrate low non-specific binding characteristics in multiplex assays. The simple and flexible immobilization chemistry enables rapid assay design providing a truly open platform for laboratory developed tests. Each Carboxyl Bead type employs a uniquely coded VeraCode microbead. The code inscribed within each microbead is used downstream to designate and track the specific analyte of interest in the multiplex reaction.

• Analytes can be labeled with standard fluorescent reporters such as phycoerythrin (R-PE), Cy3, Cy5, or AlexaFluor dyes
• During analysis, the fluorescence and code inscription for each microbead are detected by the BeadXpress Reader, which has been demonstrated to detect protein concentrations as low as 10 pg/ml in a multiplexed VeraCode Carboxyl bead assay
• The VeraCode Bead Kitting system minimizes hands-on time by virtually eliminating manual pipetting
