BACKGROUND Vitamin D deficiency and vitamin D receptor gene polymorphisms are known to be significantly associated with high myopia. Whether this genetic variant may impact primary open-angle glaucoma is largely unknown. This study investigated whether vitamin D receptor gene polymorphisms are altered in primary open-angle glaucoma subjects carrying the risk allele, and whether vitamin D defici...

Taq DNA polymerase is widely used in laboratories and for this reason many investigators have focused their attention on understanding the role of various regions and amino acids in this enzyme. O-helix is a part of taq polymerase suggested to play an important role in the enzyme fidelity. The influence of Asn666 in this helix on the enzyme function has never been investigated, and therefore by...

A Tritrichomonas foetus-specific 5' Taq nuclease assay using a 3' minor groove binder-DNA probe (TaqMan MGB) targeting conserved regions of the internal transcribed spacer-1 (ITS-1) was developed and compared to established diagnostic procedures. Specificity of the assay was evaluated using bovine venereal microflora and a range of related trichomonad species. Assay sensitivity was evaluated wi...

We investigated the use of Taq dye primer and Taq terminator sequencing chemistry to optimize the quality of sequence data obtained from templates containing homopolymer tracts and repetitive elements. In direct side-by-side comparisons using the Applied Biosystems Model 373A Fluorescent Sequencer, the Taq terminator sequencing chemistry gave much cleaner and more consistent results on long hom...

dna amplification using taq dna polymerase is one of the most widely used techniques in molecular biology and biotechnology. the aim of this study was to amplify the gene of this enzyme from a thermophilic bacteria called thermus aqauticus and clone it into a vector for future use. using specific primers the cdna of taq dna polymerase was amplified and ligated into the cloning vector ptz57r usi...
