Sejtfüggetlen

Sejtfüggetlen is a Hungarian term that translates to "cell-free" in English. It is primarily used in the context of biological research, particularly in molecular biology and diagnostics. The term refers to processes, substances, or analyses that can occur or be performed outside of a living cell.

In essence, a sejtfüggetlen system or assay does not require the presence of intact, living cells to function or to yield results. This is in contrast to cellular assays, which rely on the metabolic activity, signaling pathways, or structural integrity of cells. Sejtfüggetlen approaches offer several advantages, including simplified experimental setups, reduced variability, and the ability to study specific molecular interactions without the complexities of cellular environments.

Examples of sejtfüggetlen applications include in vitro protein-protein interaction studies, enzyme activity assays, and the detection of nucleic acids (DNA or RNA) through methods like PCR or ELISA. These techniques allow researchers to isolate and examine specific biological components and their functions in a controlled, non-cellular environment. The development of sejtfüggetlen technologies has been crucial for advancing our understanding of biological mechanisms and for the creation of diagnostic tools.
