Expression, Purification, and Characterization of Lactate Dehydrogenase from Bacteria without Codon Optimization.

is the most widespread cause of malaria, especially in subtropical and temperate regions such as Asia-Pacific and America. lactate dehydrogenase (PvLDH), an essential enzyme in the glycolytic pathway, is required for the development and reproduction of the parasite. Thus, LDH from these parasites has garnered attention as a diagnostic biomarker for malaria and as a potential molecular target for developing antimalarial drugs.

Non-structural protein 1 from Japanese encephalitis virus expressed in E. coli retains its molecular weight and immunogenicity.

Japanese encephalitis virus (JEV) is a member of the Flavivirus genus and has recently attracted attention as a high-risk pathogen in the Asia-Pacific region, with up to 30% mortality in the afflicted patients. Recent outbreaks of flavivirus-associated infections around the world have put the focus on non-structural protein 1 (NS1) as a candidate for diagnostic and vaccine researches on flaviviruses. Although the JEV NS1 protein has been expressed in eukaryotic cells, attempts to express JEV NS1 in E.
