  • Product overview

    EpiSeeker Chromatin Extraction Kit (ab117152) is a complete set of optimized buffers and reagents for isolating chromatin or DNA-protein complex from mammalian cells or tissues in a simple and rapid format. Chromatin prepared by this kit can be used in a variety of chromatin immunoprecipitation methods. It is also the recommended method for obtaining chromatin required by Abcam’s one-hour ChIP method using the EpiSeeker ChIP Kit - One Step (ab117138). The isolated chromatin can also be used in other chromatin-related applications such as in vitro protein-DNA binding assays and nuclear enzyme assays.

  • ChIP analysis of RNA polymerase II enriched in GAPDH and MLH1 promoters with chromatin extract prepared from formaldehyde fixed colon cancer cells (2x105) using ab117152.
  • Chromatin was extracted from 3x106 mouse neuroblastoma cells, fixed for 10min at RT in 0.1% formaldehyde. Cells were sonicated before last centrifugation, and following centrifugation, cells were treated with proteinase K & RNAse A.

    Chromatin yield was 4 µg chromatin/106 cells.

The extraction buffer of this kit contains a low concentration of EDTA which should not significantly affect combination use of micrococcal nuclease with this kit as Ca++ concentration is 5 mM.

The size can be checked by directly running the sheared chromatin as seen in the attached file. If DNA will be purified. The following quick method may be useful: a) Use 10 uL sample and add 40 uL H2O b) Reverse cross-link by adding 2 uL of 5 M NaC...

In general, the chromatin is easy to be sonicated to 200-1000 bps. If the chromatin extracts can not be broken down fully by sonication, it may be due to insufficient time length, power intensity, foaming of chromatin solution during sonication etc. these...

I hope the sonication step is helpful. I look forward to hearing how things go!

In general, this kit could generate about 4 ug/1 million cells of chromatin or 2 ug of DNA (histone:DNA in chromatin is about 1.8-2 :1). Based on the described conditions by the customer, the relatively low yield of DNA seems mainly due to that nucleus ar...

Thank you for your enquiry. My colleague Karen asked me to follow up with you.

How has it been determined that the chromatin is in the pellet rather than the supernatant?

Thanks in advance for the additional information!

Thank you for contacting Abcam regarding ab117152.


Regarding the protocol for tissues, it seems that this information is located in C1 for Tissues rather than at D4. For tissues, add 1ml Working Lysis Buffer for every 200mg of tissue, follow...
