Chromatin immunoprecipitation (ChIP) tests examine histone mutations and genomic DNA sequences bound to specific regulatory proteins. In ChIP, protein-DNA complexes are linked to in vivo, are immune, purified, and amplified for genetic targeting and developer of known targets or to identify new target sequences. In a microarray-based, ChIP-on-Chip, DNA immunoprecipitated DNA is labeled and packaged in high-resolution microarrays.

Chromatin is a complex of DNA and proteins found in eukaryotic cells. The main task is to pack the long DNA molecules into dense, dense structures. This prevents the fibers from binding and plays a key role in strengthening DNA during cell division, preventing DNA damage, and regulating gene expression and DNA replication. During mitosis and meiosis, chromatin facilitates the proper separation of chromosomes into anaphase; the features of chromosomes that are visible during this phase are the result of DNA being synthesized into a highly reversible chromatin.
The main components of chromatin proteins are histones, which bind to DNA and act as "anchors" in which strands are bound. DNA binds histone proteins, forming nucleosomes, and the so-called beads in the structure (euchromatin). Many histones wrap up a 30-nanometer fiber that binds nucleosome arrays in a highly concentrated form (heterochromatin). High-density DNA of 30-nm fiber produces a metaphase chromosome (during mitosis and meiosis).
The genome is a blueprint for life. It is a collection of DNA molecules that contain all the instructions for the development of living things and their ability to react to nature. Each cell contains the same blueprint but depending on how these instructions are used it will lead to a variety of cells (such as blood cells, neurons, and muscle cells) and ultimately become a complex organism. This is a huge amount of information and in fact if each DNA molecule were targeted end-to-end it would vary by 2 meters (~ 6.5 feet). Surprisingly, though, these molecules all fit into the nucleus of a cell only 0.000006 meter s wide.
Research on chromatin and chromosome biology is aimed at understanding how the genome is integrated into chromatin and the myriad mechanisms by which it is strongly regulated. Our team of scientists uses a range of test methods and computers to study this. We investigate how histone proteins are organized from cell to cell, how chromatin is regulated by the environment, how genomic information is studied in a chromatin cell, and how chromatin dysfunction leads to disease.
