인터페론 활성을 갖는 폴리펩타이드의 제조방법Method for preparing a polypeptide having interferon activity

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 rIFN-αA의 아미노산 서열 및 rIFN-αA를 코드화하는 뉴클레오티드서열을 나타낸다.1 shows the amino acid sequence of rIFN-αA and the nucleotide sequence encoding rIFN-αA.

제3도는 rIFN-αA(Gly1, Ser98)을 코드화하는 dsDNA를 제조하기 위해 이용되는 공정을 도시적으로 나타낸다.3 shows the process used to prepare dsDNA encoding rIFN-αA (Gly1, Ser98).

제5도는 rIFN-αA(Gly1, Ser98)의 발현을 위한 복제가능한 플라스미드성 발현벡터의 제조에 이용되는 공정을 도식적으로 나타낸다.5 diagrammatically shows the process used to prepare a replicable plasmid expression vector for expression of rIFN-αA (Gly1, Ser98).

그림중의 별표(*)는 시스테인을 코드화하는 뉴클레오티드 트리플렛을 대체시킨 뉴클레오티드 치환을 나타낸다.The asterisk (*) in the figure indicates nucleotide substitutions replacing nucleotide triplets encoding cysteine.
