In the regular chip seq although 10ng dna is a lot to a specific gene the amoount of dna is still very low.
Chip seq library preparation protocol.
If known positives and negatives are available perform qpcr to demonstrate enrichment for these regions.
Alternatively analysis can be by sequencing when using the chip seq method.
The tag kit for chipmentation offers an optimized chip seq library preparation solution based on tagmentation.
Chip seq library prep fast total time 1 5 hrs.
Chip seq is the primary technique used to investigate genome wide protein dna interactions.
Preparation methods for chomatin immunoprecipitated chip seq dna libraries are similar to those for standard dna.
Libraries are constructed with unique dual indexes to enable improved de multiplexing on patterned flow cells.
Simple hands on time 10 min.
High library conversion efficiency.
The new england biolabs nebnext chip seq library prep reagent set for illumina enables construction of chip seq libraries from 1 10 ng of input with minimal pcr.
However the amount of input dna for chip seq libraries is lower than for standard dna library construction and library preparation requires the use of optimized reagents and protocols.
Dna produced using this protocol is suitable for use as an input for sequencing library prep.
Antibody quality control experiment depth of sequencing multiplexing paired end reads the need for a control sample.
Preparation methods for chromatin immunoprecipitation chip seq dna libraries are similar to those for standard dna.
This kit includes reagents for tagmentation based library preparation integrated in the ip and is compatible with any chip protocol based on magnetic beads.
Chromatin immunoprecipitation with massively parallel dna sequencing chip seq has been used extensively to determine the genome wide location of dna binding factors such as transcription factors posttranscriptionally modified histones and members of the transcription complex to assess regulatory input epigenetic modifications and transcriptional activity respectively.
As part of this procedure immunoprecipitated dna must undergo library preparation to enable subsequent high throughput sequencing.
Optimize chip protocol using flag tag in case of antibody issues.
In my case the amount of dna for library preparation is low but to a specific gene.
