Feline IL-2 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.

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.

ELISpot

When a 96-well PVDF microplate is used, 1:60 dilutions of the provided capture and detection antibodies are recommended. Each investigator should determine the optimal working dilution of the antibodies depending on the type of microplate, Wash Buffer, and Blocking Buffer used.

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.

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 Feline IL-2 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.
