Production and Evaluation of Polyclonal Rabbit Anti-Human p53 Antibody Using Bacterially Expressed Glutathione S-transferase-p53 fusion protein
p53 is a key tumor suppressor gene that is targeted for inactivation during human tumorigenesis. In this study, we produced and characterized polyclonal antihuman p53 antibody. The cDNA encoding the completehuman p53 protein was cloned into pGEX-4T-1 and expressed in Escherichia coli as a fusion protein with Schistosoma japonicum glutathione S-transferase (GST). The rabbits were immunized...
متن کاملReduction of MTT by glutathione S-transferase.
The reduction of the tetrazolium salt 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) to a blue formazan product is widely used for assaying cell survival and proliferation. The reduction reaction is catalyzed by dehydrogenases localized in the mitochondria of viable cells. As part of an analysis of the ability of glutathione S-transferase (GST) enzymes to protect cells from...

doxorubicin8). Inhibitors of this enzyme, ethacrynic acid and piriprost are already known and their potential therapeutic utility in combination with alkylating agents has been suggested by Tew and his colleagues9). Our group has been screening for novel inhibitors of glutathione S-transferase from microbial origin and we recently isolated tryptophandehydrobutyrine diketopiperazine10) (TDD) and...
متن کاملA ligand function of glutathione S-transferase.
Glutathione S-transferases (GSTs) are ubiquitous enzymes and abundant in plants. They are intimately involved in plant metabolism and stress defense related to reactive oxygen species. Our project assigned particular reactions including novel ones to certain GST-isoforms. Transformed E. coli was used to express recombinant GST-isoforms from maize. An N-terminal His tag allowed their purificatio...
متن کاملGenetic Polymorphism of the Glutathione S-Transferase M1 and Development of Breast Cancer
Glutathione S-transferases (GSTs) are encoded by a superfamily of genes and play a role in the detoxification of potential carcinogens. The human GSTs are divided into four classes: alpha, mu, pi and theta. Previous studies indicated that the absence of the Glutathione S-Transferase M1 (GSTM1) protein correlated with an increased risk of developing some types of cancers. Association between spe...
