Abstract

Indonesia and 13 other countries are included in High Burden Countries (HBC) in Tuberculosis (TB) cases. One of the problems in TB control in Indonesia is detecting latent TB appropriately. Diagnosis of latent TB does not have a gold standard. Some tests to detect latent TB have limitations in TB endemic areas such as Indonesia. Therefore, we need a fast, effective, and accurate method to diagnose TB. One of the potential proteins is MPT63, which is coded by the Rv 1926c gene. It is known that MPT 63 can induce Th1 cell reactivity and proliferation of IFN-λ. The purpose of this research was to clone and produce the recombinant protein MPT 63 from Mycobacterium tuberculosis. The method is Rv 1926c ligation to the pQE30-Xa expression vector and transformation to Escherichia coli BL21 host cell. Recombinant protein production was carried out by growing recombinant clones Rv1926-pQE on Luria Bertani medium by IPTG induction. The transformation results obtained white colonies and blue colonies. The growth of Escherichia coli BL21 carrying a recombinant plasmid is characterized by a change in the color of the medium. MPT63 recombinant protein was characterized by SDS-PAGE with a size of 16 kDa.
