title: The immunoglobulin class of anti-hapten antibody secreted during secondary responses in vitro and in vivo.
abstract: A comparison has been made of the in vitro and in vivo response of primed mouse spleen cells to the hapten DNP. The responses were analysed in terms of six classes (sub-classes) of humoral antibody directed against the cross-reacting hapten TNP. By comparison with the response in intact mice the adoptive secondary response is delayed by 3 days in addition to being somewhat lesser in magnitude. The timing of the response in vitro is similar to that observed in intact mice. The preponderant class in all three responses was gammaG1 with gammaA and gammaG3 secreting cells consistently comprising the smallest proportion of the total of antibody-secreting cells.
