The genetic markers associated with economic traits have been widely explored for animal breeding. Among these markers, single-nucleotide polymorphism (SNPs) are gradually becoming a prevalent and effective evaluation tool. Since SNPs only focus on the genetic sequences of interest, it thereby reduces the evaluation time and cost. Compared to traditional approaches, SNP genotyping techniques in...

We report a comparative study of two DNA extraction techniques, thermolysis and chemical lysis (CTAB), for molecular identification and genotyping of M. tuberculosis. Forty DNA samples were subjected to PCR and the results demonstrated that with thermolysis it is possible to obtain useful data that enables fast identification and genotyping.

Introduction . Blood transfusion is a strong practice in traumatology, internal medicine, haematology, obstetrics and transplantation, which demands safety of haemotransfusion with estimating the red blood cell group antigens donor recipient blood. Routine immunotyping techniques usually provide for an antigen identification to weak subgroups, albeit certain inherent limitations serology tests ...

A generic genotyping assay utilizes a fixed set of reagents, which is independent of the actual target sample, to determine all present alleles. An example is the interrogation of several amplicons spanning polymorphic sites using an all k-mer array. Due to the high cost associated with a genotyping experiment, it is desirable to design a set of experiments, which maximizes the number of SNPs t...

To date, microarray-based genotyping of large, complex plant genomes has been complicated by the need to perform genome complexity reduction to obtain sufficiently strong hybridization signals. Genome complexity reduction techniques are, however, tedious and can introduce unwanted variables into genotyping assays. Here, we report a microarray-based genotyping technology for complex genomes (suc...

Short tandem repeats (STRs) are commonly used as genetic markers. The detection and analysis of STRs can be used to gather information on polymorphisms of interest to forensic geneticists. Denaturing polyacrylamide gel electrophoresis (PAGE) is an affordable method for the detection of minor sequence changes in DNA, while capillary electrophoresis (CE) is the gold standard for genotyping analys...

The new field of genomics has emerged from conventional human genetics and is, at present, moving extremely rapidly. As a result, this chapter will be a snapshot in time, capturing a moment in the state of development. For this reason it will not dwell in detail on individual technologies or machines, as many of these will be obsolete in a very short time, but rather on the principles of high-t...

Typing of microbial pathogens, or identifying bacteria at the strain level, is particularly important for diagnosis, treatment, and epidemiological surveillance of bacterial infections. This is especially the case for bacteria exhibiting high levels of antibiotic resistance or virulence, and those involved in nosocomial or pandemic infections. Strain typing also has applications in studying bac...
