LIQUID FOR EJECTION AND EJECTING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a liquid for ejection, capable of stably ejecting a solution containing at least 1 kind of a protein and a peptide by an inkjet method utilizing thermal energy and to provide a method for ejecting the liquid containing at least 1 kind of the protein and the peptide by using the liquid for ejection.

SOLUTION: By adding a compound simultaneously having a guanidine group and a carboxyl group or a sulfonic acid group in one molecule to an aqueous solution containing at least 1 kind of protein and peptide, stability for the ejection in the inkjet method utilizing the thermal energy is improved.
