Abstract
We found a repetition of CA dinucleotides on the second intron of mouse polymeric immunoglobulin receptor (PIgR) gene. This repetition is genetically polymorphic among mouse strains and was used as a simple sequence length polymorphism marker to map the PIgR gene. Alleles of this and other SSLP markers were determined with PCR for progenies from a back cross between C57BL/6J mice and F1 heterozygotes of AKR/J and C57BL/6J. This mapping located the pIgR gene between D1Mit200 and D1Mit218 of the mouse chromosome 1.
