Background: Subunit vaccines are appropriate vaccine candidates for the prevention of some infections. In this study, three immunogenic proteins of Mycobacterium tuberculosis, including HspX, Ppe44, and EsxV as a new construction, were expressed alone and as a fusion protein to develop a new vaccine candidate against tuberculosis infection. Methods: To make the fusion protein, the three genes ...

plant fatty acyl-acyl carrier protein thioesterase (fat) is a major enzyme regulating the amount and composition of fatty acids in lipids. in this study, one type of cdna, corresponding to the fatty acyl-acyl carrier protein (acyl-acp) thioesterase (fat) enzyme, was isolated from the seed of brassica napus cv. ningyou12. blast results revealed that the cdna identified highly with the fatb class...

The recombinant protein of heterologous proteins in Escherichia coli strains K12 has various and different systems tested demands a detailed insight into the multiple factors affecting encoded protein. One crucial is acceptable quality DNA copies inserted inside bacteria. Firstly, amplification procedure needed to be performed well; thus, designing primer selecting optimum annealing temperature...
