Nuclear Matrix: Methods of Preparation


The nuclear matrix is the non‐chromatin component of the nucleus, which consists of the nuclear envelope and the inner fibrous web forming a scaffold for attachment of DNA. Sequential extraction of isolated nuclei with DNAase and high‐salt buffers yields a residual structure – the nuclear matrix.

Keywords: nuclear matrix; matrix isolation; nuclear architecture; nucleic acid metabolism; nuclear scaffold
