GMP ActiveMax ® Human T Cell Activation/Expansion CD3/CD28 Beads are uniform 5.5 μm magnetic beads coated with an optimized mixture of GMP-grade mouse monoclonal antibodies targeting CD3 and ...

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 ...

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 ...

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 ...

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 ...
