Isolation of tumor-infiltrating lymphocytes by ficoll-paque density gradient centrifugation

Research output: Chapter in Book/Report/Conference proceeding › Chapter

Abstract

With the renewed enthusiasm in immuno-oncology, characterization of the tumor immune microenvironment constitutes an essential and unique aspect to the assessment of therapeutics. The isolation of tumor-infiltrating lymphocytes (TILs) is a desirable approach toward the understanding of antitumor immune response. This chapter provides an effective protocol to mechanically dissociate tumor tissue and generate single-cell suspension from excised tumors. TILs are then isolated by Ficoll-Paque density gradient centrifugation. This protocol is applicable to both human and experimental tumors in immunocompetent murine models.
