Lysine is possibly effective for cold sores (herpes simplex labialis) treatment. Lysine is available under the following different brand names: L-lysine and Lysine Monohydrochloride.

1. L-lysine monohydrochloride has been used: as a component in pre-fixative solution for electron microscopy. as a component in blocking solution for immunohistochemistry(IHC) in the preparation of Periodate-lysine-paraformaldehyde (PLP) fixative for IHC.

1. L-Lysine Monohydrochloride is one of the largest industrially produced amino acids in the world. Lysine is an essential or indispensable amino acid.

Lysine (symbol Lys or K)^[2] is an α-amino acid that is used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated −NH₃⁺ form under biological conditions), an α-carboxylic acid group (which is in the deprotonated −COO⁻ form under biological conditions),

L LYSINE MONOHYDROCHLORIDE
