    I have a question about the binding/elution condition of the DNA purification slurry provided in the ChIP kit (ab500). From reading the protocol, it is not clear to me what is the exactly the condition used to elute the DNA from the slurry. Could you p...

    DNA purification slurry is often used for DNA extraction. The extraction is set up under aqueous alkaline conditions. In this environment, the slurry has an increased affinity for heavy metal cations such as Ca2+, Mn2+, and Mg2+. Nuclear DNA and RNA re...

    ab500 ChIP, Runx2 binding to target promoters

     Excellent Good 4/5 (Ease of Use)
    Abreviews
    Chromatin immunoprecipitation. ab500 ChIP Kit (abcam) was used according to the manufacturer’s instructions. Briefly, VSMCs were trypsinsed, centrifuged and then washed in ice-cold PBS. Cells were centrifuged again and then fixed in 1.1% Formaldehyde in PBS. Reactions were quenched with glycine and cells were washed in ice cold PBS before being lysed. Chromatin was sheared to approximately 500-1000 bp fragments using a sonicator at 4 °C. Chromatin was diluted and input chromatin was collected. Remaining chromatin was used for ChIP using 4 ug Runx2 (D130-3) as antibody of interest, 4 ug anti-histone H3 as a positive control and no antibody as a negative control. Antibodies were added for 12 hours at 4 °C and then Protein A sepharose beads were used to precipitate protein/DNA complexes. Cross-links were reversed by heating at 98 °C followed by Proteinase K addition and DNA purification. Samples were analysed by pPCR.

    I would like to ask if the ChIP Kit is also useful for other cell cultures (i.e. Bacterial)



    Looking forward to your reply!





    The use of ab500 ChIP kit has not been validated so far on bacteria.

    The part of the protocol that may need some optimization is the chromatin preparation. Actually, lysis of bacteria is more complex than lysis of eukaryotic cells and may...

    What percentage of formaldehyde should be used?

    the concentration of formaldehyde needed for the kit is actually 1% but you could use any percentage below 4%. 1% is just what was used in our lab.

    ChIP Assay in HeLa cells

     Good Average 3/5 (Ease of Use)
    Abreviews
    Experimental set up:
    HeLa cells treated with 1 µM Dexamethasone (Dex) for 6h.
    IP was performed with 4.0 µg rabbit anti-GR antibody (H-300, Santa Cruz).

    Recommendations for product and protocol optimization:
    - Step A2
    Spin cells for 5 min instead of 10 min at 500 g at 4°C (not RT) for saving time and to avoid aberrant DNA interactions that might occur if time between harvest and cross linking is too long.

    - Step B8
    Using a sonication device with a sounding rod with a total lysate volume of 100 uL (3 ChIP assays) is difficult to handle. As a consequence, you easily lose much sample by dispersion. Better incubate cell pellet in the indicated 100 uL buffer D/PI mix for 5 min on ice and add 1X ChIP buffer (containing PI) to a volume of 350 uL. After sonication, add 580 uL 1X ChIP buffer (incl. PI) to the lysate (step D2). From this step the total volume for each sample will be as indicated in the manual. Sonication of bigger sample volume will not compromise the outcome of your experiment!

    - Step B11
    Spin sonicated lysates for 10 min instead of 5 min at 14,000 g at 4°C.

    General remark:
    Switching temperatures from spinning to RT at step A2 and A3 does not change the experimental results. Better keep 4°C constantly.

    I am using your ab500 CHIP kit and I was wondering if there was anywhere in the protocol where there could be a stopping point.

    It is possible to freeze the sheared chromatin and resume the ChIP at a later time, but once the ChIP has started, it is not possible to stop.

    In the protocol there are two steps for using DNA purifying slurry (1st: reverse cross-link to see whether the sonication worked 2nd: actual reverse cross-link). According to the protocol, I need to use 100 micro lt each time. That means 200 micro lt f...

    The kit is for 24 assays. It is 100 µl per ChIP. With 3000 µl DNA purifying slurry, you can do 30 ChIPs. But you are correct, you have to also use 100 µl per INPUT. So with this kit, you can do 24 assays + 6 INPUT.

    I'm using ab500 kit for ChIP assay on my HEK293 cell line. I performed the procedure according to your protocol and it works ok. However, last time I used it I observed SDS precipitate in the D buffer during sonication on cool water bath. There was no ...

    Thank you for your inquiry.

    I am happy to confirm that it is normal to have precipitation at 4°C in buffer D. This is due to the SDS as you said in your email.

    It is important to bring the buffer to room temperature before addin...

    Hi,
    I have a query regarding EpiSeeker Chromatin Extraction Kit. I want know if this kit is compatible for FUNGI chromatin extraction. I am planning to do chip seq to study sec metabolite regulation in fungi.

    Thank you for your enquiry regarding ab500.

    We never tested this kit on FUNGI chromatin. You may need to optimize first the shearing conditions. Afterwards, if you use a specific antibody to FUNGI chromatin, the kit will probably work.
