Application

NXTRACT kit was used to study the impact of salt on cardiac differential gene expression and coronary lesion in normotensive mineralocorticoid-treated mice. It was also used to test the therapeutic potential of andrographolide for treating endometriosis.

General description

The procedure for the nuclear protein extraction method is to allow cells to swell with hypotonic buffer. The cells are then disrupted, the cytoplasmic fraction is removed, and the nuclear proteins are released from the nuclei by a high salt buffer.

Other Notes

A number of different procedures in the detailed technical bulletin enable the selection that best fits a particular application. For example, choose between detergent and non-detergent extraction of nuclear protein or between the standard hypotonic lysis buffer for most cell types and isotonic lysis buffer for fragile cells. In addition, the kit provides a procedure for salt reduction from the nuclear extract with dilution buffer. NuCLEAR offers the flexiblity you need for optimal protein extraction. Extracts can be prepared in less than 2 hours and are highly pure since there is little or no cross-contamination between nuclear and cytoplasmic extracts.
Recommended Antibodies for Immunodetection L1293, N2662, AMAB90549
Within this kit is a complete system for preparing nuclear and cytoplasmic protein extracts from mammalian tissue or cultured cells. All reagents necessary for extraction are included.

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. What are the options for lysis of my cells to make extracts when using Product NXTRACT, CelLytic™ NuCLEAR™ Extraction Kit?

    The use of detergent will lead to maximum protein yield. However we find that the hypotonic lysis is extremely effective and in addition for very fragile cells we offer an isotonic lysis option.

  3. Can Product NXTRACT, CelLytic™ NuCLEAR™ Extraction Kit, be used to make nuclear protein extracts for EMSAs/DNA binding studies?

    Several references describe the use of the N-XTRACT kit in sample preparation for EMSA work.1. Xie, J., et al., β2-Microglobulin as a negative regulator of the immune system: high concentrations of the protein inhibit in vitro generation of functional dendritic cells. Blood, 101(10), 4005-4012 (2003).2. Marambaud, P., et al., A CBP Binding Transcriptional Repressor Produced by the PS1/ε-Cleavage of N-Cadherin Is Inhibitedby PS1 FAD Mutations. Cell, 114, 635-645 (2003).3. Chen, G., et al., Phosphorylated FADD induces NF-κB, perturbs cell cycle, and is associated with poor outcome in lung adenocarcinomas. Proc. Nat. Acad. Sci. USA, 102(35), 12507-12512 (2005).

  4. Is Product NXTRACT, CelLytic™ NuCLEAR™ Extraction Kit, suitable for use on tissues? 

    We have used the kit with several tissues: Mouse lung and brain, Rat liver and Rabbit muscle. For these tissues we usually used the kit with 100 mg tissue. After extraction with 140 μl Extraction buffer, we obtained an average yield of protein concentration as follows: 3.2 mg/ml for brain, 4.1 mg/ml for lung, 3.3 mg/ml for muscle and 10 mg/ml for liver.

  5. When using Product NXTRACT, CelLytic™ NuCLEAR™ Extraction Kit, what can I use for the mechanical lysis of my cells?

    We recommend the use of a glass tissue homogenizer, with a type B pestle, or alternatively a syringe with a narrow-gauge (No. 27) hypodermic needle may be used.

  6. How "pure" is the nuclear extraction using Product NXTRACT, CelLytic™ NuCLEAR™ Extraction Kit? 

    It is important to keep in mind that this kit will provide a crude nuclear fraction.  Depending on the care taken at the step where the nuclei are pelleted and the supernatant containing the cytoplasmic fraction is removed, we have found that the cytoplasmic contamination of the nuclear pellet may be a few percent.

  7. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

Granulocyte-macrophage colony-stimulating factor (GM-CSF) and macrophage colony-stimulating factor (M-CSF) independently stimulate the proliferation and differentiation of macrophages from bone marrow progenitor cells.
