As part of this procedure immunoprecipitated dna must undergo library preparation to enable subsequent high throughput sequencing.
Chip seq library preparation protocol.
The tag kit for chipmentation offers an optimized chip seq library preparation solution based on tagmentation.
Simple hands on time 10 min.
We recommend using our troubleshooting tips to optimize this protocol for your particular experimental conditions.
If known positives and negatives are available perform qpcr to demonstrate enrichment for these regions.
Input dna amount from 5 ng to 30 ng.
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.
Alternatively analysis can be by sequencing when using the chip seq method.
Libraries are constructed with unique dual indexes to enable improved de multiplexing on patterned flow cells.
Preparation methods for chromatin immunoprecipitation chip seq dna libraries are similar to those for standard dna.
Chip seq is the primary technique used to investigate genome wide protein dna interactions.
Antibody quality control experiment depth of sequencing multiplexing paired end reads the need for a control sample.
This kit includes reagents for tagmentation based library preparation integrated in the ip and is compatible with any chip protocol based on magnetic beads.
High library conversion efficiency.
Dna produced using this protocol is suitable for use as an input for sequencing library prep.
In the regular chip seq although 10ng dna is a lot to a specific gene the amoount of dna is still very low.
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.
Chip seq library prep fast total time 1 5 hrs.
However the amount of input dna for chip seq libraries is often lower than for standard dna library construction.
Optimize chip protocol using flag tag in case of antibody issues.
