Patent ID: 10612155

Abstract:
Provided are a protein crystal device and method for crystallizing protein capable of generating protein crystal without imparting a heat effect, a protein crystal-cutting device and method for cutting protein crystal capable of cutting protein crystal without imparting a heat effect on protein crystal, and bubble-jetting member and protein-adsorbing-bubble-jetting member used in said device. A bubble-jetting member is used in a protein crystal device to jet bubbles into a protein solution to thereby allow protein crystals to be obtained, the bubble-jetting member comprising: a core formed of a conductive material; a shell part formed of an insulating material, including an extended section extending from the tip of the core, and in which at least a portion closely adheres to the core to cover the core; and a gap having a bubble-jetting port, the gap being formed between the extended section and the tip of the core.
