PRODUCT SUMMARY
Complete ELISpot kits are highly sensitive, microplate-based assays for the detection of cytokine secreting cells. Kits are available for detection and enumeration of a single analyte or two analytes simultaneously. Complete ELISpot kits are ready-to-run and require no assay development or refinement. ELISpot Development Modules contain the basic components required to develop an ELISpot assay. They offer an economical alternative to buying separate antibodies.

ELISpot development modules are an alternative to ELISpot kits. A basic understanding of ELISpot assay development is required for the successful use of these reagents. Each investigator should optimize the coating conditions, the assay sensitivity, the type of enzyme and substrate, as well as the concentrations of the capture and detection antibodies to achieve desired results. The analyte-specific ELISpot Development Module and the ELISpot Blue Color Module contain the necessary components for analyte detection and visualization, respectively. These modules can be used together but are sold separately. Each module contains enough reagents for at least five 96-well microplates.


PRODUCT FEATURES

  • An economical alternative to ELISpot Kits
  • Optimized capture and detection antibody pairings and recommended concentrations save lengthy development time
  • Generic development protocols provide direction to start an optimization protocol
  • Customize the assay to your specific needs

Preparation and Storage

Stability & Storage
Store the unopened product at -20 to -70 °C. Use a manual defrost freezer and avoid repeated freeze-thaw cycles. Do not use past expiration date.

Background: IL-2

IL-2 (Interleukin 2) is a critical cytokine in T cell biology. It promotes T cell activation and expansion, the development, maintenance and function of regulatory T cells (Treg), and the differentiation of CD8+ T cells into terminal effector cells and memory cells. IL-2 signals through a receptor complex composed of CD25/IL-2 R alpha, IL-2 R beta, and the Common gamma Chain (gamma c). IL-2 R beta is also a component of the IL-15 receptor complex. Gamma c is also a signaling subunit in the receptors for IL-4, -7, -9, -15, and -21.

Long Name:
Interleukin 2
Entrez Gene IDs:
3558 (Human); 16183 (Mouse); 116562 (Rat); 396868 (Porcine); 280822 (Bovine); 403989 (Canine); 100034204 (Equine); 751114 (Feline); 100302458 (Rabbit)
Alternate Names:
aldesleukin; IL2; IL-2; IL-2lymphokine; interleukin 2; interleukin-2; involved in regulation of T-cell clonal expansion; T cell growth factor; T-cell growth factor; TCGF
