||Recombinant Human Prothymosin, Alpha (aa 1-99) is Expressed inE. coli. Native sequence representing mature prothymosin α (ProTα) isolated from human cells (no affinity-tags, no additional added (linker) sequences). Purified from overproducing bacterial strains by a phenol extraction procedure, DEAE chromatography, and ethanol precipitation.
||The exact length of the human protein is 109 aa corresponding to the NCBl data base entries AAH34921 and TNHUA. The N-terminal M is absent in the mature protein (otherwise, it would be 110). ProTα is acetylated at the N-terminal S. MALDI-MS data for the recombinant ProTα isolated from bacteria show that the protein is partially acetylated.
||Stimulates mouse thymocytes comparable to native ProTα.
||Liquid. 50µg dissolved in sterile water.
