Polymorphic restriction endonuclease sites within the HLA-DR alpha gene have been defined, localized, and used as genetic markers in the analysis of susceptibility to insulin-dependent diabetes mellitus (IDDM). Hybridization of Bgl II-digested human genomic DNA with a cDNA clone for the HLA-DR alpha chain (pDR alpha-1) has revealed three allelic restriction fragment lengths: 3.8 kilobase pairs ...
A novel PCR restriction analysis method using the RNA polymerase beta-subunit- coding gene (rpoB) was employed to both detect and identify Helicobacter pylori in biopsy specimens and culture isolates. The rpoB DNAs (458 bp) were specifically amplified by PCR with the Helicobacter-specific primers (HF and HR). Based on the determined rpoB sequences of the culture isolates, an H. pylori-specific ...
A heterologous probe encoding phenylalanine ammonia-lyase (PAL) was used to identify PAL clones in cDNA libraries made with RNA from young leaf tissue of two Populus deltoides x P. trichocarpa F1 hybrid clones. Sequence analysis of a 2.4-kb cDNA confirmed its identity as a full-length PAl clone. The predicted amino acid sequence is conserved in comparison with that of PAL genes from several oth...
