Abstract
We describe a microculture system for the generation of CTL and T helper cells against peptides. Tryptic digest and cyanogen bromide fragments of chicken ovalbumin and synthetic peptides of ovalbumin (323–339) and influenza virus (NP 365–380) were used to generate CTL and T helper lines from unprimed T cells. These lines were both peptide-specific and MHC-restricted. The relative ease of generating peptide-specific, MHC-restricted CTL and helper T cell lines with as few as 10 6 unprimed lymphocytes can be an efficient method of detecting potential immunogenic determinants of an antigen.
