title: Limiting dilution analysis of antigen-specific T cells.
abstract: Limiting dilution analysis (LDA) has been extensively employed as a quantitative method to estimate the precursor frequency of various T lymphocyte subsets according to their functional properties in vitro. We describe here an example of LDA experiment assessing antigen-specific T cell proliferation of microcultures in the presence or absence of adjuvant and illustrate how to estimate the frequencies of precursor T cells using an online tool that we made publicly available.
