A vector driving the expression of foreign cDNAs in the MHC class II-positive cells of transgenic mice.

ABSTRACT

We describe a plasmid vector that drives the expression of foreign cDNAs in transgenic mice, according to the dictates of an MHC class II gene promoter. Using this vector, we have often obtained mRNA and protein synthesis with a tissue and cell-type specificity indistinguishable from that of the endogenous MHC class II genes.
