EJECTION LIQUID, EJECTION METHOD, METHOD OF MAKING DROPLETS FROM LIQUID, CARTRIDGE AND EJECTION DEVICE |
摘要 |
<p>The present invention provides a liquid composition, as an ejection liquid used for stably ejecting liquid droplets, including at least one kind of a protein and a peptide, and a compound having a betaine skeleton by application of thermal energy to the liquid; a method of making droplets form the liquid; and an ejection method and an ejection device suitable for utilizing protein liquid droplets. By adding a compound having a betaine skeleton to an aqueous solution of at least one kind of a protein and a peptide, the liquid composition is improved in stability for ejection by application of thermal energy. Further, a surfactant may be further added to the liquid composition containing the compound having a betaine skeleton, and in this case the effect of stable ejection can be obtained.</p> |
