Abstract
An ejection liquid capable of being stably ejected based on a system using thermal energy even if the liquid contains at least one selected from the group consisting of proteins and peptides, and a method and an apparatus for ejecting the liquid containing at least one selected from the group consisting of proteins and peptides using this system are provided. The applicability of the liquid for use in an inkjet system using thermal energy is improved by adding at least one selected from the group consisting of amino acids and salts thereof and a surfactant to an aqueous solution containing at least one selected from the group consisting of proteins and peptides.
