Scrape loading assay
WebJan 20, 2024 · The commonly used technique for in vitro assessment of GJIC is so-called scrape loading-dye transfer assay (SL-DT) using a membrane-impermeable and gap junction-permeable fluorescent dye, typically Lucifer Yellow (457 Da, negatively charged), which is introduced into adherent cells typically grown in a Petri dish. WebMay 1, 2000 · Several in vitro assays have been developed to determine the effect of chemicals on gap junction communication in cultured cells. The scrape loading dye transfer technique is based on studying the transfer of the fluorescent dye Lucifer Yellow in cells where the dye is loaded through a cut in the cell monolayer.
