What is a CLIP assay?
Cross-linking immunoprecipitation (CLIP) is a method used in molecular biology that combines UV cross-linking with immunoprecipitation in order to analyse protein interactions with RNA or to precisely locate RNA modifications (e.g. m6A).
How does ChiRP seq work?
ChiRP-Seq works via affinity capture of a target complex of lncRNA and chromatin by tiling antisense-oligos. This technique will allow scientists to generate a map of genomic binding sites of several hundred bases very accurately due to high sensitivity and low background.
What is transcriptome sequencing?
The set of genes which are transcribed in any one condition is known as the transcriptome, and the process of determining the genetic codes contained in the transcriptome, and their relative proportions, is known as transcriptome sequencing.
What is RNP immunoprecipitation?
RIP (RNP immunoprecipitation) analysis enables the rapid identification of endogenous RNAs bound to an RBP and to monitor time-dependent changes in this association, as well as changes in response to different metabolic and stress conditions.
What is the difference between ChIP-seq and RNA-seq?
ChIP-seq is run to map the global binding sites of the studied transcription factor, and RNA-seq is measured from the wild type and knockout model to identify genes regulated by the TF.
What is the difference between ChIP and ChIP-seq?
Similar to ChIP-chip, ChIP-seq provides information about genome-wide protein binding. However, unlike ChIP-chip, ChIP-seq uses NGS technology to identify DNA fragments and map them against the entire genome.
Are Chirp books free?

What are the different types of RNA sequencing?
Key RNA-Seq Methods

- Targeted RNA Sequencing.
- Ultra-Low-Input and Single-Cell RNA-Seq.
- RNA Exome Capture Sequencing.
- Total RNA Sequencing.
- Small RNA Sequencing.
- Ribosome Profiling.
What RNA-seq tells us?
RNA-seq can tell us which genes are turned on in a cell, what their level of transcription is, and at what times they are activated or shut off. This allows scientists to understand the biology of a cell more deeply and assess changes that may indicate disease.
How is extension initiated in Sanger sequencing?
In chain terminator sequencing (Sanger sequencing), extension is initiated at a specific site on the template DNA by using a short oligonucleotide ‘primer’ complementary to the template at that region.
What is sequencing and how does it work?
Sequencing results in a symbolic linear depiction known as a sequence which succinctly summarizes much of the atomic-level structure of the sequenced molecule. DNA sequencing is the process of determining the nucleotide order of a given DNA fragment.
What is chain termination in DNA sequencing?
So far, most DNA sequencing has been performed using the chain termination method developed by Frederick Sanger. This technique uses sequence-specific termination of a DNA synthesis reaction using modified nucleotide substrates.
How do you interpret ChIP-DNA sequences?
Through the analysis, the sequences can then be identified and interpreted by the gene or region to where the protein was bound. After size selection, all the resulting ChIP-DNA fragments are sequenced simultaneously using a genome sequencer.
