    The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
    Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
  • 货期：
    Basically, we can dispatch the products out in 1-3 working days after receiving your orders. Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
    Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
  • 注意事项：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
  • 产品描述：

    The production of this Recombinant Human ERAS protein started with the ERAS gene synthesis. And then using recombinant DNA technology, the ERAS gene was inserted into an expression vector so that we could get the recombinant express plasmid of ERAS. Transform the plasmid into the cells of E.coli, culture the cells and we could get the desired Recombinant Human ERAS protein. But the work was not completed, protein purification and a strict QC system were performed in the last step. The purity is 90%+ determined by SDS-PAGE.

    ERAS (also named HRAS2 or HRASP) is a gene providing an instruction of making a protein named GTPase ERas (ERas) in human. The protein encoded by this gene is also known as Embryonic stem cell-expressed Ras and belongs to Ras family found in murine embryonic stem (ES) cells in 2003. Increasing studies has been reported that ERAS may provide resistance to chemotherapy in different human tumorigenic cells through activation of the PI3K/AKT/mTOR pathway, promoting both DNA replication and transcription.
