In Vivo Assay for Detection of Antigen-specific T-cell Cytolytic Function Using a Vaccination Model

The overall goal of this experiment is to allow for detection of in vivo antigen-specific killing of a target cell in a murine model. This method can help answer questions in immunology field, such as sufficiency and detection of antigen-specific cytolytic killing of target cells in an attacked immune system and how this could be modified by manipulation of the T-cells to enhance the function in vivo. The main advantage of this technique is that it allows the researcher to assess antigen-specific cytolytic potential directly and quickly, as the assay is not depend on tumor growth or infection.

Presenting this procedures will be Cara Haymaker, and Yared Hailemichael to instruct us from Department of Melanoma Medical Oncology. After anesthetizing mice, according to the text protocol, use 70%isopropyl alcohol to spray the tail base area for injection. Using a 27 gauge needle attached to a syringe, and with the bevel side facing up, penetrate four to five millimeters into the tail base region and inject 100 microliters of previously prepared peptide solution.
