title: The analysis of an anti-fluorescein response at limit dilution: the effect of lymphokine preparations on the apparent specificity.
abstract: The specificity of cytotoxic T cells in an anti-fluorescein response has been analysed at limit dilution. According to the ability to discriminate between fluoresceinated and non-fluoresceinated targets, the apparent specificity of CTL depends on the quality and quantity of the lymphokine preparations used to support the response. An acid-labile component of the factor preparations contributes to the generation of non-specific CTL. No cytotoxicity against NK-sensitive target cells was detected in the 'non-specific' component of the responses.
