Cell Sample Processing in Proteomics
1. Cell Separation
The initial step involves the separation of cells, typically achieved through mechanical or enzymatic methods. Mechanical separation primarily involves physical methods to dissociate cells from tissue, whereas enzymatic separation utilizes enzymes to degrade intercellular connections.
2. Cell Disruption
Following separation, cells require disruption to facilitate the extraction of intracellular proteins. Methods for cell disruption include sonication, freeze-thaw cycles, and chemical treatments.
3. Protein Extraction
Subsequent to disruption, the extraction of proteins from cells is conducted, frequently employing centrifugation, filtration, and ultrafiltration techniques. These procedures yield purified protein samples.
4. Protein Purification
The final step is the purification of protein samples, which involves a series of chemical and physical techniques to eliminate extraneous components from the disrupted cells, isolating the desired proteins. This is a sophisticated and precise procedure.
These represent the typical stages of cell sample processing in proteomics. Specific procedures may differ based on the cell type and the targeted proteins in study. Through these processes, high-quality protein samples can be obtained, laying the groundwork for further proteomic research.
