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.

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.

Other Notes

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.
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.

Organelle Isolation

The isolation of subcellular fractions by centrifugation is a commonly used technique and is widely applicable across multiple cell and tissue types. Because organelles differ in their size, shape, and density, centrifugation can be easily employed to separate and purify organelle fractions from gently homogenized samples.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
