Title: Method for purification of protein
Inventor: LEE DAE-SHIL
IPC: C12N9/00

Granted: 1994-03-09
Abstract: Separation and purification of specific protein from fused protein are achieved by changing physical properties of proteins with affinity peptide. This method comprises : A) introducing DNA sequence which codes 7-15 amino acids at the binding point of aimed protein coding genes and other peptides or protein coding gene; B)forming affinity peptide composed of 7-15 amino acids between protein and other peptide; and C) identifying protein with different affinty to metal salt. The above affinty peptide is a homopeptide which is composed of 7-15 glutamic acid or 7-15 hystidine. The method can purify proinsulin.

Abstract: 자성체로 구성되는 헤드칩을 고정하기 위한 헤드 베이스를 도전성 수지재료를 사용하여 형성한다. 이것에 의하여 단품의 헤드 베이스를 복수 한번에 제조가 가능한 한편, 복수의 헤드 베이스를 일체화로 형성할 수 있다. 또 이 헤드 베이스에는 헤드칩을 매설하여 형성할 수 있으므로 헤드칩의 접착 공정을 생략할 수 있다. 또한 복수의 헤드칩을 베이스에 매설하여 성형할 때, 성형 금형에 의하여 각 헤드칩의 수평 방향 및 높이 방향의 위치 정밀도를 낼 수 있다. 또, 헤드칩의 대전 방지가 용이하다. 또 헤드의 경량화를 도모할 수 있으므로 회전 드럼에 배치할 때 밸런스용의 더미 베이스가 필요없고, 또 베이스 성형시에 동시에 더미 베이스를 형성할 수 있다. 
     또, 헤드 베이스 위에 형성된 헤드칩 첩착부에 있어서의 표면을 다른 부분보다 거칠게 형성하여 칩 접착 강도를 상승시킬 수 있다.
