In order to analyze multifunctional antigen-specific T cells, freshly isolated splenocytes (1.5 × 106) were seeded in 96-well plates and stimulated with 5 μg/mL Ag85B or 1 μ/mL ESAT-6 antigens. As a positive control, cells were stimulated with 100 ng/mL PMA and 1 μg/mL Ionomycin. After 4 h incubation, cells were blocked and fixed, as described in Flow cytometry of mouse cells paragraph. Subsequently, cells were stained with FITC-conjugated CD3, PerCP/Cy5.5-conjugated CD4, Brilliant Violet 510™-conjugated CD8a, APC-conjugated TNF-α, PE/Cy7-conjugated IL-17A, PE/Cy5-conjugated IL-2 and Brilliant Violet 421™-conjugated IFN-γ antibodies (all from BioLegends), all diluted 1:100, and analyzed by flow cytometry.

Antigen-specific T cell proliferation assay

Check if the same lab product or an alternative is used in the 5 most similar protocols
Freshly isolated splenocytes (1 × 10E6) were seeded in 96-well plates and stimulated with 5 μg/mL Ag85B antigen or 1 μ/mL ESAT-6 antigen. As positive control, the cells were stimulated with 1 μg/mL α-CD3 (BioLegends). Antigen-specific T cell proliferation was analyzed after 6 days of incubation with antigens. The cells were blocked, as described above, and subsequently stained with PerCP/Cy5.5-conjugated CD4, Brilliant Violet 510™-conjugated CD8a, FITC-conjugated CD44, PE-conjugated CD62L and Brilliant Violet 421™- conjugated CD90.2 antibodies (all from BioLegends), all diluted 1:100. After staining, the cells were fixed using eBioscience™ Foxp3/Transcription Factor Staining Buffer Set and permeabilized using eBioscience™ Permeabilization Buffer, according to the manufacturer's instructions. Subsequently, cells were intracellularly stained with 1:50 diluted APC-conjugated Ki-67 antibody (BioLegends) and analyzed by flow cytometry.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
