Overview
Improved Spot Recovery and Spot Definition
Elispot assays are used for a range of applications to monitor immune responses and immunological response patterns, and can also be used to identify antigenic peptides and create vaccination strategies. Validated Elispot assays are highly reliable, reproducible and predictive. They can successfully identify antigenspecific T or B cells on a single cell level with results that closely mirror in vivo conditions and eliminate the need for long-term in vitro cell cultures or the addition of exogenous cytokines.
New: 8-Well Strips now available for processing less than 96 samples at one time.
MultiScreenHTS filter plates are available with validated Immobilon®-P (PVDF) for superior results. Plates with HA (mixed cellulose esters) are also available. Both provide membranes with dense uniform pore structure to promote antibody binding and increase sensitivity for better, sharper spot definition.
- Validated membranes
- Uniform spot morphology
- Easy membrane access
- Compatible with automation
Protocol
| 1. | Coat membrane with antibodies. Add immune cells and incubate |
| 2. | Responding cells produce cytokines. The cytokine of interest is then bound by the antibody |
| 3. | Wash to remove cells. Add biotinylated antibodies which bind to the cytokine-antibody complex |
| 4. | Add avidin-enzyme conjugate |
| 5. | Add enzyme substrate and each responding cell will result in one spot |
Product Performance
3D well image rendering provides valuable insights in per cell cytokine productivity.
