  • 产品描述：

    Just like other recombinant proteins, the production of this recombinant Human CTAG1A protein began with appropriate cDNA and PCR methods, and then the CTAG1A expression plasmids were built. Following sequence determination of the constructs, plasmids were transformed into Mammalian cell for the expression of the recombinant Human CTAG1A protein. C-terminal FC-Myc tag was used in the process. And we finally get the protein of interest with purity of 85%+.

    CTAG1A (also called CTAG, CTAG1, ESO1, LAGE2, LAGE2A) is a gene encoding a protein called cancer/testis antigen 1 in human. The protein encoded by this gene is also known as autoimmunogenic cancer/testis antigen NY-ESO-1 (NY-ESO-1),cancer/testis antigen 6.1 (CT6.1) and L antigen family member 2 (LAGE-2). CTAG1A is an identical copy of the CTAG1B gene. The protein encoded by CTAG1A gene is one of the most immunogenic tumor antigens defined to date, because it induces spontaneous humoral and CD8+ T cell responses against NY-ESO-1 in 40%+ to 50%+ of patients with advanced NY-ESO-1–expressing tumors.
