We investigated the possibility that specific antibody against TN-C is useful for detecting cardiovascular diseases as a molecular diagnostic reagent. Heavy chain variable region (VH) and light chain variable region (VL) genes of anti-TN-C antibody were obtained from total RNA in hybridoma, and were performed overlap-extended PCR. Expression vector inserted VH-linker-VL gene (scFv) was used in E. coli, in vitro cell free (RTS wheat germ) and mammalian cell line (HEK293) expression systems. As a result, the antibody expression was highly effective in HEK293 cell line system. As soon as it’s ready, we are planning to experiments of antibody accumulation in foci of myocarditis model mice., 2012年度~2014年度科学研究費補助金(若手研究(B))研究成果報告書, 24791291}, title = {ScFv化抗テネイシンC抗体による心疾患の分子標的イメージング診断法の確立}, year = {2015} }
