Protocol
This procedure is to be used for blocking, it is not routinely tested for each batch. 1. In the appropriate tissue culture medium dilute TC11-18H10 NA/LE mAb with the highest concentration of 12 µg/ml at a 1:4 series dilution in the tissue culture hood for a total of 7 different concentrations. 2. Add 50 µl into each well. For the negative control, add 50 µl tissue culture medium. 3. Set the triplicate for each testing concentration of TC11-18H10 NA/LE antibody . 560268 4. Dilute the rmIL-17A in the tissue culture medium to 40 ng/ml. Add 50 µl into each well. Tap the plate to mix the mAb and rmIL-17A together. 5. Incubate the plate in 37°C, 5% CO2 incubator for 1 hour. 6. Count the log phase NIH-3T3 cells and dilute the cells to 5x10^5 cell/ml. Seed 100 µl cells into each well. 7. Incubate the cells in 37°C, 5% CO2 incubator for 24 hours. 8. Harvest the supernantant. Check the IL-6 concentration from each well using the BD Cytometric Bead Array Mouse IL-6 Flex Set. 9. Calculate the IL-6 concentration of each well from the standard curve. Calculate the mean of each concentration triplicate and plot a chart

The TC11-18H10 antibody reacts with recombinant and natural mouse IL-17A proteins. IL-17A, also known as CTLA-8, is a T cell-derived cytokine that promotes inflammatory responses. Mouse IL-17A is a proinflammatory cytokine that can induce the release of IL-6 by mouse stromal cells. It has been shown to support the growth of hemopoietic progenitors in vitro, it can also stimulate granulopoiesis in vivo. The TC11-18H10 antibody has been reported to neutralize IL-17A activity. Recent studies have shown that IL-17A is produced by a unique subset of Th17 cells that develop along a pathway distinct from the Th1- and Th2- cell differentiation pathways. The mouse IL-17A cDNA was isolated from a cDNA library generated from TCRalphabeta+CD4-CD8- thymocytes. Functional studies of TC11-18H10 mAb by neutralization of mouse IL-17A bioactivity. Recombinant mouse IL-17A (2 ng/well) was pre-incubated with various amounts of TC11-18H10 mAb or medium as a control in a 96-well plate for 1 hour at 37°C. Following the incubation, NIH-3T3 cells were added at 5x10^4 cells per well and incubated at 37°C. After 24 hours of incubation, the supernatant was harvested and the concentration of IL-6 was quantified using BD™ Cytometric Bead Array Mouse IL-6 Flex Set (Cat. No. 558301).
