U2OS-ZFN-SNAP-Nup107 Cells

The U-2 OS-ZFN-SNAP-Nup107 cell line represents a specialized variant of the widely used human osteosarcoma cell line U-2 OS. This particular model has been engineered to express the SNAP-tagged version of the nucleoporin Nup107, a pivotal component of the nuclear pore complex, which is essential for the transport of molecules between the nucleus and the cytoplasm. The integration of the SNAP-tag technology allows for the biorthogonal labeling and visualization of Nup107 in live or fixed cells, providing a powerful tool for studying nucleocytoplasmic transport and nuclear pore complex architecture under physiological conditions.

The U-2 OS background offers several advantages, including robust growth rates and a well-characterized karyotype, which support high-throughput screening applications and genomic studies. The ZFN (Zinc Finger Nuclease) technology used in this cell line facilitates targeted genome editing, enhancing the precision with which researchers can investigate the genetic contributions to nuclear transport and other cellular processes. This cell line is particularly useful for studies aimed at elucidating the dynamics and regulation of nuclear pore complexes in cancer biology and cellular physiology.

Due to the specialized nature of the U-2 OS-ZFN-SNAP-Nup107 no.294 cell line, it is highly suited for advanced imaging techniques, including super-resolution microscopy, to explore nucleoporin functions at unprecedented detail. It is also a valuable resource for developing therapeutic strategies targeting nuclear transport pathways implicated in various diseases, including cancer. The SNAP-tag component adds versatility for further biochemical and proteomic analyses, making it an indispensable tool in the field of cellular and molecular biology.
