  • Product overview

    Nuclear Extraction Kit (ab113474) provides a simple and selective method along with all necessary reagents for extracting nuclear proteins in just 1 hour for a variety of applications such as western blotting, protein-DNA binding assays, nuclear enzyme assays or any other procedures requiring optimized nuclear proteins. The protocol is fast and easy-to-use, and also isolates very abundant yields of nuclear extract from mammalian cells or tissue samples.

    Compared to other kits that use conventional nuclear extraction methods, the buffers included in ab113474 contain much lower amounts of salts (80% less than conventional kits) and no SDS, which would allow the enzyme activity to be better kept in the nuclear extracts.

    • Nuclear extracts were prepared from MCF-7 cells and the activity of HDACs were measured using different amounts of the extract. The result shown in the figure demonstrates the ab113474's high specificity.

    Yes, this kit can be definitely used for frozen tissues. The lab confirmed it.

    Thank you for your inquiry.

    We have two Nuclear Extraction Kits in our catalog at the moment:

    Yes, the cytosolic fraction when using ab113474 Nuclear Extraction Kit includes membrane proteins.

    Thank you for the follow up message.

    I can confirm that the concentration of DTT included in the kit is 1M.

    I hope this will be helpful. If you have any further questions, please do not hesitate to contact me.

    This kit will work better with 2 million cells however you can still use this with half a million cells, when using with 500,000 cells please keep the volume of buffers and reagents proportional to 1 million cells.

    We recommend using Bradford ...

    I contacted the laboratories. They confirmed that PIC is not required for the tissue homogenization preparation protocol as the active proteases in tissue are much less than that in cultured cells.

    I can confirm that if the cytosol is not required for much consideration, DTT can be excluded in pre-lysis buffer too.

    Yes you can use ab113474, EpiSeeker Nuclear Extraction Kit, to purify soluble nuclear proteins from tissue culture cells or tissues and then detect HIF1 alpha in that extract using ab133104, HIF-1 alpha Transcription Factor Assay Kit.

    A rotor-stator homogenizer even at low speed may disrupt the nuclear membrane. We recommend using a Dounce homogenizer for isolating intact nuclei.

    Nuclear Protein extraction and Histone protein extraction from cell samples frozen at -80oC could still work using ab113474 and ab113476. However, the enzyme activity of nuclear extracts from frozen tissues may be much lower than that from fresh tissues.
