A specific antibody to the target protein is covalently coupled to internal fluorescently dyed beads. The beads with bound target proteins are separated by laser excitation and quantitated. Beads ...

Scientists at UMC Utrecht have developed a new technology to efficiently isolate a specific subset of gut bacteria from fecal ...

The percentage of panel-reactive antibodies (PRAs) can be determined by calculating the percentage of beads that react positively with patient sera. Figure 2 shows schematic histograms of positive ...

Scientists have developed a new technology to efficiently isolate a specific subset of gut bacteria from fecal samples that are recognized by IgA antibodies. These 'IgA-coated' bacteria are associated ...

Currently, antibodies are the standard reagents for ... The fluorescent label on the protein allows beads that retain it to be identified sensitively, and the large amount of unreacted compound ...

Moreover, the high antibody density on beads creates an avidity phenomenon, increasing sensitivity. Indeed, in a direct comparison of AlphaLISA assays and ELISAs for measuring human insulin in ...

Flexible: Study any analyte of choice using your own antibodies and customized assay protocols. Homebrew kits are available on both bead and planar platforms, enabling assays to be run on any HD-1 ...

anti-CD28 antibody, or CD3/CD28 magnetic beads, along with the addition of relevant growth factors to activate T cells. During this process, the CD28-mediated co-stimulatory signal plays a central ...

Patients that have antibodies to latex will react against the beads themselves, thus resulting in a positive shift of all beads, irrespective of the presence of HLA antibodies, which renders the ...

Services provided include reverse phase protein arrays (RPPA) with over 260 antibodies for total and phosphoproteins of major cell signaling pathways and Luminex bead technology for multiplex ...
