Poly lysine solution is more widely used tissue section and glass glue, the cationic polymer molecules interact with the anion on the tissue section will produce a strong adhesion force. The properties of the flask surface are very important for cell culture. The glycoprotein (negative) on the cell surface is easy to adsorb on the hydrophilic surface, so the cell culture surface with a considerable amount of positive charge can promote cell adsorption, which is the importance of optimizing the cell culture surface with poly-L-lysine.

It is suitable for anti-slide processing of slides used in histology, immunohistochemistry, frozen section, cell smear, in situ hybridization, etc., to prevent tissue slides from falling off during experimental procedures. It can also be used in cell culture to increase cell adhesion ability.

Poly-L-lysine polymers can be used to promote cell adhesion to solid substrates for scientific research.
