A novel DR beta 1*03 allele identified by polymerase chain reaction-restriction fragment length polymorphism.

This report describes a new MHC class II allele, HLA-DR beta 1*0306, discovered in a 31-year-old Norwegian male. The allele typed serologically as DRw52 (DR3) and amplified in PCR using DR52-associated group primers. This product could not be identified using established restriction digests, however. Use of Asp 700, Msp I, Hha I, Bse RI, Mnl I, Hph I, and Bsrb I gave banding patterns expected for a DR beta 1*03011 allele, but Rsa I had an additional site at codon 47. Sequencing showed a single base change at this position, with the substitution of tyrosine for phenylanine in this new allele. The biologic impact of this substitution remains to be determined.

Identification of Candida species by PCR and restriction fragment length polymorphism analysis of intergenic spacer regions of ribosomal DNA.

The PCR was used to amplify a targeted region of the ribosomal DNA from 84 Candida isolates. Unique product sizes were obtained for Candida guilliermondii, Candida (Torulopsis) glabrata, and Candida pseudotropicalis. Isolates of Candida albicans, Candida tropicalis, Candida stellatoidea, Candida parapsilosis, and Candida krusei could be identified following restriction digestion of the PCR products.
