생쥐 배종양 세포에 있어서 tPA 유전자 발현에 관한 연구
權戊植 성균관대학교 생명과학자원연구소 1994 生命資源科學硏究 Vol.1 No.1
F9 murine embryonal carcinoma cells expresed gene for tissue plasminogen activator(tPA), upon differentiation in vitro induced by retinoic acid(5×10 exp(-6)M/1). A recombinant plasmid(pBTPA) capable of tPA sense and antisense RNAs was constructed, and used for the RNA protection assay for tPA gene transcript in the differentiated F9 cells.

미분화된 F9 세포에서 JunB에 의한 AP-1 활동의 유도
權戊植 成均館大學校 科學技術硏究所 1992 論文集 Vol.43 No.1
A full-length JunB cDNA was inserted into an eukaryotic expression vector, pHBAPr-l-neo(or, LK444), to construct a JunB cDNA expression plasmid, LK_4JunB. Undifferentiated murine embryonal carcinoma cells(F9 22 : 5 X 10 exp (6)/10ml) were cotransfected by the calcium phosphate method with DNAs of LK_4LAC(1.5㎍), 3 X TRECAT(3㎍) along with or without PvuII-cut LK_4JunB(8,㎍), in order to test a plausible role of the JunB or AP-1 activity. It was revealed that the cells cotransfected with the LK_4JunB showed some 20 times higher the CAT reporter gene activity than the value obtained from the cells without the LK_4JunB. This finding strongly suggest the fact that the JunB should have the AP-1 activity.

Endo-B, the mouse form of Keratin 18, is the first member of the large intermediate filament gene family to be expressed during embryogenesis. Thus, the differentiation of cultured murine embryonal carcinoma cells has been used as a convenient model system of early mouse development. F9,22(mouse embryonal carcinoma) cells were treated with retinoic acid (5 x 10_6M/l) for 72 hours, and then they were fixed with the mixture of glutaraldehyde(2%) and formaldehyde(2%) in phosphate buffered saline for 5 min at 4℃. The fixed cells were immunoreacted with the rabbit anti-Endo-B antiserum. Endo-B was visualized by reaction with rhodamine conjugated goat anti-rabbit antibodies. Some of the differentiated F9 cells exhibited strong fluorescence indicating the expression of Endo-B filament.

Bacillus 殺蟲 蛋白質(CryIC)抗體 生産과 그 應用에 관한 硏究 : Its Application To Plant Biotechnology
권무식 성균관대학교 생명과학자원연구소 1997 生命資源科學硏究 Vol.4 No.2
Bacillus thuringiensis spps., gram-positive soil bacteria, are characterized by their ability to produce crystalline inclusions during sporulation. Inclusions are proteins exhibiting a highly specific entomocidal activity. One of the inclusions, CryIC is specifically toxic to lepidopteran insects. The gene CryIC(7.43kb) has been isolated from Bacillus thuringiensis entomocidus 60.5 and ligated to pTZ vector. The recombinant plasmid named to pSB607. The pSB607 was transformed to E.coli JM109. A number of transformants were selected. The CryIC was purified using differential solubility. The protein was treated with trypsin to increase it's toxicity. They were observed by SDS-PAGE. The activated CryIC was used as an immunogen. Some 600㎍ of the immunogen were hypodermally injected on the hide back & thighs of a rabbit to generate antisera against CryIC. Titration of anti-CryIC antisera has been achieved by blotting or ELISA. In western blot, 2.34ng antigen was detected. A mutant clone of the CrylC is under construction.

A solid-phase electro-blot procedure was used for immunoassay of mammalian pyrurate dehydrogenase(E1) subunits a(Ela) and b(Elb). E1(porcine kidney) was fractionated by sodium-dodecyl sulfate polyacrylamide gel electrophoresis. Ela and Elb proteins were electrophoretically transferred onto nitrocellulose membrane with a constant current of 70mA as a function of time. The adsorbed proteins(Ela & Elb) were immunoreacted with rabbit anti-E1(porcine kidney) antiserum, then the immunoadsorbed Ela and Elb were identified by goat anti-rabbit IgG-horseradish peroxidase conjugate immunoassay kit. It has been found that the solid-phase immunoassay sensitivity of Ela and Elb increased in accordance with increment of transfer time up to a certain point under these experimenal conditions.

3-oxoacid CoA-transferase cDNA 클론의 혈청학적 동정
權戊植 성균관대학교 기초과학연구소 1987 論文集 Vol.38 No.2
A cDNA clone for 3-oxoacid CoA-transferase was identified in a λgtll expression gene bank with a monospecific polyclonal rabbit anti-rat 3-oxoacid CoA-transferase. The cDNA clone bank was constructed from poly(A^+) RNA isolated from rat(12 day-old) brains. The cDNA clone was subcloned into M13mp18 and used for further characterization.

웨스턴 전이 : 피루브산 탄산효소 (흰쥐 간) Pyruvate Carboxylase (Rat liver)
權戊植 成均館大學校 科學技術硏究所 1987 論文集 Vol.38 No.2
Pyruvate carboxylase isolated from the mammalian rat and mouse livers were subjected to sodiumdodecyl sulfate-polyacrylamide gel electrophoresis. The pyruavte carboxylase on the gel was electrically transferred to pure nitrocellulose membrane (average pore size : 0.2㎛). The enzyme (antigen) immobilized on the nitrocellulose membrane, was identified by a double antibody assy. The Bio-Rad ImmunBlot(Goat Anti Rabbit-Horse Radish Peroxidase Conjugate) Assay Kit (Bio Rad Co.) was employed here. The electroblot conditions were best optimized for the pyruvate carboxylase. The detailed procedures were discussed in the text.

Klebsiella pneumonia에서 Quinoprotein의 발현에 대한 면역학적 고찰
권무식 성균관대학교 생명공학연구소 2000 生命工學硏究 Vol.6 No.1
Pyrroloquinoline quinone (PQQ) is an molecule found in many enzymes called quinoproteins, i.e., alcohol dehydrogenases, amine oxidases, decarboxylases, in a broad spectrum of biological materials. It has been considered a very important molecule for physiological property as a enzymatic cofactor. It has been, therefore, interesting to develop a sensitive method to identify the quinoproteins in organisms. Monospecific polyclonal antiserum specific to PQQ was raised in a rabbit as fllow. The PQQ was conjugated to bovine serum albumin (BSA) by 1-Ethyl-3-(3-dimethyl-aminopropyl) carbodiiminde HCI (EDC) mediated reaction. The PQQ-BSA conjugate was purified by gel filtration. The conjugant was emulsified with adjuvant. The emulsion was hyperdermaly injected to a rabbit. PQQ-lipase conjugate was made to use as an antigen for the anti PQQ-BSA conjugate antiserum. The titer of the antiserum was determined by indirect solid phase immunoassay. The antiserum showing the highest titer recognised nano-gram quantity of PQQ-lipase conjugate. Also, we raised anti PQQ antiserum in a rabbit to examine quinoproteins in a prokaryote, Klebsiella, pneumonia.
