Assignment of the gene for porcine insulin-like growth factor binding protein 1 to chromosome 18 and detection of polymorphisms in intron 2 by PCR-RFLP.

We have obtained a partial cDNA and three BAC clones for the porcine insulin-like growth factor binding protein 1 gene (IGFBP-1). Results of fluorescence in situ and radiation hybrid (RH) mapping assigned this gene to porcine chromosome (SSC) 18q24-qter. We found two types of polymerase chain reaction-restriction-fragment-length polymorphisms (PCR-RFLP) in intron 2 by using FokI and AluI.
