Despite the fact that microarray-based chromatin immuneprecipitation (ChIP) method, ChIP-chip, is gradually being replaced by the emerging sequencing-based method such as ChIP seq, both methods are currently being used in many laboratories as a major tool to survey transcription factor binding patterns, study various histone modifications in an unbiased manner.
Through using the micro-electro-mechanical system (MEMS) technology and the chemical vapour deposition (CVD) method, chips were designed and fabricated on a p-type 〈100〉 double-side polished silicon wafer with a high resistivity.
As input for this method, ChIP-Seq clusters and mappable genome regions were used.
The fact that we independently found, by an unbiased method (ChIP-seq), that Rfx6 binds to the very same region in the Gck promoter as Rfx3 strongly supports that Rfx transcription factors are important regulators of Gck expression.
This study uses a different method (ChIP-Seq) to map cenH3 and comes to a very different conclusion: in addition to the broad domains, they identify ∼700 discrete locations for cenH3 and conclude that the centromeres of C. elegans are in fact similar to the point centromeres of yeast.
Subsequently, global targets of these core factors have been identified in mouse ES cells using ChIP combined with paired-end-tag-based sequencing methods (ChIP-PET) [ 27] and in human ES cells using ChIP-chip [ 28].
Studies of protein association with DNA on a genome wide scale are possible through methods like ChIP-Chip or ChIP-Seq.
Waldminghaus and Skarstad recently reported, in this journal, a modified method for ChIP-chip.
We developed a modified ChIP-chip method, designated ChAP-chip (Chromatin Affinity Precipitation coupled with tiling chip).
Chromatin immunoprecipitation combined with massively parallel sequencing methods (ChIP-seq) is becoming the standard approach to study interactions of transcription factors (TF) with genomic sequences.
Recently, chromatin immunoprecipitation has been combined with high throughput sequencing methods (ChIP-Seq).
