Abstract
Description
또한, 본 발명의 목적은 상기 발현 벡터로 형질전환된 숙주세포를 제공하는 것이다.
따라서 본 발명의 일태양에 따라, 서열번호 3의 염기서열을 프로모터 하위에 포함하는 발현 벡터가 제공되며, 바람직하게는 도 1의 유전자 지도를 가지는 발현 벡터가 제공된다. 본 발명의 발현 벡터는 BsiW I 제한효소 부위(restriction site)에 항체의 경쇄 카파 가변영역을 코딩하는 유전자가 효과적으로 도입될 수 있다.
본 발명의 다른 태양에 따라, 상기 발현 벡터로 형질전환된 숙주세포가 제공되며, 바람직하게는 E.coli XL1-Blue/pHAB-KC (수탁번호 : KCTC 10230BP)인 숙주세포가 제공된다.
상기 본 발명에 따른 발현벡터는 경쇄 카파 가변영역을 코딩하는 유전자를 상기 제한효소 부위에 직접 카세트 형식으로 삽입(클로닝)하므로서 가변영역 유전자와 불변영역 유전자가 연결된 경쇄 카파 전체 유전자를 생산할 수 있다.
