FAIRE is based on phenol chloroform mediated sample separation, in which accessible chromatin fragments can be separated from the condensed state, effectively enriching for regulatory genomic regions (schematically visualized in Fig 2A).
(2) Amidases produced by S. aureus wild type bacteria would shave and remove the most accessible PGN fragments at the surface of bacteria, eliminating the binding sites for PGRPs.
However, the atl mutant would release intact muropeptides, easily detected by PGRP-SA, and therefore would be unable to evade detection by the innate immune system; Hypothesis 2: S. aureus wild type bacteria shave and remove accessible PGN fragments at the surface of bacteria, eliminating the binding sites for PGRPs.
The rationale for our approach was that limited digestion with DNase I will generate small DNA fragments from accessible chromosome regions and larger fragments from less accessible regions, allowing separation by size-fractionation methods.
In general, the more accessible the DNA fragments the more likely surrounding genes were actively transcribed.
Pretreatment of biomass makes lignin fragments accessible by disrupting the lignocellulosic structure, and ensures the production of high-quality pellets.
For all pairs of protein fragments that are accessible to solvent and ligand fragments, the spatial distributions are mapped on the query protein surface, by superimposing the protein fragments for the three representative atoms (Supplementary Table S1).
In the two patients with documented migration, as well as in two others in which a large metallic fragment was accessible and considered to pose a potential risk, we removed these with the aid of an image-guided neurosurgical navigation system.
We used satellite imagery to identify the forest fragments located within the boundaries of a given village, and visited accessible and permitted forest fragments within the boundaries of that village.
The precipitated nucleus is then subjected to a Tn5 transposase-based and carrier DNA-mediated protocol to amplify the fragments within accessible regions (Fig. 1a).
