Mouse Granzyme B ELISpot Development Module, 5 Plate

The complete ELISpot kit is highly sensitive, a microplate-based method for detecting cytokine secreting cells. The kit can be used to detect and enumerate one or two analytes simultaneously. The complete ELISpot kit is ready to run and does not require analytical development or improvement. The enzyme-linked immunosorbent assay module contains the basic components required for enzyme-linked immunosorbent assay. They provide an economical option for purchasing individual antibodies.

The ELISpot development module is an alternative to the ELISpot kit. A basic understanding of the development of ELISpot analysis is necessary for the successful use of these reagents. Each researcher should optimize coating conditions, detection sensitivity, types of enzymes and substrates, and the concentration of capture and detection antibodies to achieve the desired results. The analyte-specific ELISpot Development Module and ELISpot Blue Color Module contain components required for analyte detection and visualization, respectively. These modules can be used together, but sold separately. Each module contains enough reagents for at least 5 96-well microplates.

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

Washing of plates can be done using a multi-channel micropipette. In washing steps not requiring sterile conditions(C1-C5), a regular ELISA plate washer can also be used, provided that the washing head is adapted to the ELISpot plates.

Granzyme family serine proteases are stored in the granules of cytotoxic T lymphocytes and natural killer cells. Granzymes contain one S1 protease domain and are synthesized as preproproteins. Granzymes are released toward pathogen infected or transformed target cells during cellular immune reactions. Target cell entry by granzymes is through perforin channels. Granzymes trigger apoptosis by caspase-dependent and -independent mechanisms. There are five granzymes (A, B, G, H and K) in human and many more in mouse and rat.

1.Calculate the total volume of Capture Antibody needed and dilute to the working concentration in PBS.
2.Immediately add 100 µL of the diluted Capture Antibody or antigen per well. Cover the microplate with the lid and incubate overnight at 2-8 °C.
3.Aspirate each well and wash 3 times with Wash Buffer or PBS (350 µL/well) using a squirt bottle, manifold dispenser, or autowasher. After the final wash, remove any remaining liquid by inverting the microplate and blotting it against a clean paper towel.
4.Block membranes by adding 200 µL of Blocking Buffer to each well. Incubate for 2 hours at room temperature.
5.Aspirate or decant Blocking Buffer. Rinse with the same media in which the cells will be cultured.
6.Aspirate culture media from the microplate, and immediately fill the appropriate wells with 100 µL of culture media containing mouse Granzyme B secreting cells. Incubate at 37°C in a 5% CO2 incubator.
7.Wash the microplate 4 times with Wash Buffer. Remove any remaining Wash Buffer by inverting the microplate and blotting it against a clean paper towel.
8.Calculate the total volume of Detection Antibody needed and dilute to the working concentration in Reagent Diluent.
9.Add 100 µL of the diluted Detection Antibody or biotinylated antigen per well. Cover the microplate with the lid and incubate overnight at 2-8 °C.
10.Aspirate Detection Antibody or biotinylated antigen and wash as described in step 3. Microplates are now ready for color development.
