I mean, I growth PC12 cells on PLL coverglass and the whole cell was attached (cell body, "axon", growth cone) but I don't want that, only I want the cell body and growth cone attachment
I like a mixture of borate buffer with poly l lysine for the PC12 cells. https://science.nichd.nih.gov/confluence/display/mic/Coating+Coverslips+with+Poly-L-Ornithine+or+Poly-L-Lysine
