I would like to know how to coat a specific area (for example: the center of the slide only) with collagen typ1? Should I coat the whole slide then use a blade to scrape the undesired coated area?
I suggest masking areas you do'nt want to coat with lab film (parafilm or similar) and removing them afterwards.
Simply cover the undesired area with a film like parafilm or aluminum foil
You can simply use an insulator to mask the areas you don't want to cover.
