Scrape loading assay
WebFeb 1, 1987 · Scrape-loading has been effectively utilized to introduce macromolecules into cells in culture by inducing a transient tear in the plasma membrane without affecting cell viability or colony-forming ability [27]. The tracer dye Lucifer yellow (MW 457.2) is an intensely fluorescent 4-ammophthali- mide with a high quantum yield of about 0.25 [28, 29]. WebProtein Extraction Protocol Steps. Discard the medium in culture dishes with cells and wash the cells using ice-cold PBS. Discard the PBS, add ice-cold lysis buffer. Scrape the cells using cold plastic cell scraper. Collect the cells in microcentrifuge tubes. Agitate the contents in microcentrifuge tubes for 30 min at 4 °C.
