Bangs Laboratories Adds Carboxylate-Modified Beads to QuantumPlex™ Product Line

Indianapolis, IN. In early 2001, Bangs Laboratories released both GAM and streptavidin-coated QuantumPlex™ beads to be used for multiple analyte-detection research applications in flow cytometry. Bangs Laboratories has now released another addition to their QuantumPlex™ product array, carboxylate-modified microspheres.

Similar to the anti-Mouse IgG and streptavidin-coated QuantumPlex kits, the carboxylate-modified beads are available in 4.4 and 5.5 micron sizes. Each kit consists of 5 or 10 bead sets, dyed with varying amounts of BLI's proprietary fluorochorme, Starfire Red™, which are suitable for use with any flow cytometer. Narrow and cleanly separated peaks, with no overlap, correspond to the five different levels of fluorescence. A 10-bead kit allows users to detect up to 10 analytes per sample, or analyze 5 samples for two analytes.

Complimentary to the anti-Mouse IgG and streptavidin coatings permitting conjugation of specific ligands, the benfits of the carboxylate-modified beads include their versatile and direct covalent binding of ligands to the surface. Surface titration data measured for the beads provides an indicator of ultimate binding capacity.
