Human Latent TGF-beta 1 ELISpot Development Module, 5 Plate

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
