Recombinant Human TOX-11R Protein

Product Name: Recombinant Human TOX-11R Protein
Catalog #:  HTF-2838
Manufacture:  LD Biopharma, Inc.
Intruduction:

Human Thymocyte Selection-Associated High Mobility Group Box Protein TOX gene encodes a transcription factor. TOX protein contains a HMG box DNA binding domain. HMG boxes are found in many eukaryotic proteins involved in chromatin assembly, transcription and replication. TOX function regulates T-cell development, especially in controlling CD8+ T cell exhaustion during chronically infection.

       

Full-length human TOX cDNA (525aa, derived from BC016665) was constructed with codon optimization using gene synthesis technology and expressed with a small T7-His-TEV cleavage site Tag (29aa) fusion at its N-terminal and 11 arginine (11R) tag at its C-terminal. It 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.

Applications:
  1. May be used for in vitro TOX mediated gene transcription regulation study in T cell cell’s differentiation by intracellular delivery of this TOX-11R protein directly in vitro cell culture.
  2. May be used for mapping TOX protein-protein interaction.
  3. May be used as specific substrate protein for kinase, and ubiquitin (Sumo pathway) related enzyme functional screening assays.
  4. Potential biomarker protein / therapeutic target protein for T cell function related diseases, such as controlling T cell activities in vivo, et al.
  5. As native Human TOX immunogen for its specific antibody production.
Quality Control: Purity: > 90 % by SDS-PAGE.
