HRP-2019 Recombinant Human CT78-11R Protein $300

Recombinant Human CT78-11R Protein

Product Name: Recombinant Human CT78-11R Protein
Catalog #:  HRP-2019
Manufacture:  LD Biopharma, Inc.

Human Testis-specific Y-encoded protein 1 (TSPY1, also named as CT78) encodes 308aa protein which may be involved in sperm differentiation and proliferation. Normally, this gene expression is restricted in human testis tissue, but it also expressed in a wide variety of cancer tissues. As such, CT78 is a good candidate protein for anti-tumor vaccine development. CT78 is located in the gonadoblastoma critical region and is preferentially expressed in tumor germ cells of gonadoblastoma specimens.

Full-length human CT78 cDNA (307aa, derived from BC121113) was constructed with codon optimization gene synthesis and expressed with a human Alpha Fetal protein at N-terminal and 11 arginine (11R tag) at C-terminal. This protein was expressed in E. coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
