Human placental DNA is isolated from donor placenta, but will contain some maternal DNA. The DNA fragments are sonicated to produce fragments of consistent size.
Anwendung
Deoxyribonucleic acid from human placenta is used as blocking agent in Southern hybridizations. It was used to compare the efficiency of DNA quantification methods.[1]
For use in Southern hybridizations.
Komponenten
DNA is supplied in a solution of 10mM Tris-HCl (pH 8.4), with 1mM EDTA.
Six commercial preparations of human genomic DNA were quantified using five quantification methods: UV spectrometry, SYBR-Green dye staining, slot blot hybridization with the probe D17Z1, Quantifiler Human DNA Quantification kit and RB1 rt-PCR. All methods measured higher DNA concentrations than
Engineered sequence-specific nucleases and donor DNA templates can be customized to edit mammalian genomes via the homologous recombination (HR) pathway. Here we report that the nature of the donor DNA greatly affects the specificity and accuracy of the editing process
In mammals, cytosine methylation is predominantly restricted to CpG dinucleotides and stably distributed across the genome, with local, cell-type-specific regulation directed by DNA binding factors. This comparatively static landscape is in marked contrast with the events of fertilization, during which

With the completion of the human genome sequence, attention turned to identifying and annotating its functional DNA elements. As a complement to genetic and comparative genomics approaches, the Encyclopedia of DNA Elements Project was launched to contribute maps of RNA
As modern humans migrated out of Africa, they encountered many new environmental conditions, including greater temperature extremes, different pathogens and higher altitudes. These diverse environments are likely to have acted as agents of natural selection and to have led to
