Q5: What is the difference between the uncoated and high adhesion (-HA) glass bottom dishes?

“The HA dishes utilize glass coverslips which have been specially cleaned and optimized for cell attachment and spreading. The high adhesion dishes (e.g. P35G-1.5-14-C-HA) are not coated with an extracellular matrix but many researchers find that the -HA dishes give better and more consistent attachment and growth of cells.”
