An Improved Method for Measuring Chromatin-binding Dynamics Using Time-dependent Formaldehyde Crosslinking
Author:

[Abstract]  Formaldehyde crosslinking is widely used in combination with chromatin immunoprecipitation (ChIP) to measure the locations along DNA and relative levels of transcription factor (TF)-DNA interactions in vivo. However, the measurements that are typically made do not provide unambiguous information about the dynamic properties of these interactions. We have developed a method to estimate binding kinetic parameters from time-dependent formaldehyde crosslinking data, called crosslinking ...

Identification of Insertion Site by RESDA-PCR in Chlamydomonas Mutants Generated by AphVIII Random Insertional Mutagenesis

[Abstract]  Chlamydomonas reinhardtii is frequently used as a model organism to study fundamental processes in photosynthesis, metabolism, and flagellar biology. Versatile tool boxes have been developed for this alga (Fuhrmann et al., 1999; Schroda et al., 2000; Schroda, 2006). Among them, forward genetic approach has been intensively used, mostly because of the high efficiency in the generation of hundreds of thousands of mutants by random insertional mutagenesis and the haploid ...

Chromatin Affinity Purification (ChAP) from Arabidopsis thaliana Rosette Leaves Using in vivo Biotinylation System
Author:
Date:
2018-01-05
[Abstract]  Chromatin Affinity Purification (ChAP) is widely used to study chromatin architecture and protein complexes interacting with DNA. Here we present an efficient method for ChAP from Arabidopsis thaliana rosette leaves, in which in vivo biotinylation system is used. The chromatin is digested by Micrococcal Nuclease (MNase), hence the distribution of nucleosomes is also achieved. The in vivo biotinylation system was initially developed for Drosophila melanogaster ...
