        FAQ
        Q：Why do proteins need to be lyophilized? What are the effects on proteins?
        A：Proteins are heat sensitive and lyophilization allows the protein to be stored with maximum activity, extended shelf life, and reduced transportation costs. The effects of lyophilization on proteins include the possibility of partial inactivation, aggregation and other denaturation problems. However, these negative effects can be minimized by adding protective agents (stabilizers, additives, excipients) and controlling the various conditions of lyophilization.

        Q：How to store the products?
        A：Because of the difference of the products, please read the instructions carefully and store them properly according to the instructions.

        Q：Why do some proteins have Fc tags?
        A：A recombinant protein may be fused to the Fc region of IgG for multiple reasons. It can be used for purification, for detecting the protein with an anti-IgG antibody in a binding assay, or to encourage the formation of disulfide-linked homodimers which increases the bioactivity of some recombinant proteins.

        Q：What is trehalose，and what is its function?
        A：Trehalose is a reliable and safe carbohydrate. Trehalose can obviously prevent the secondary structure change of protein and the extension and aggregation of protein during freeze-drying. To prevent the damage caused by freezing, it can also make the protein more resistant to water when freeze-dried, thus reducing the possibility of precipitation when the product is re-dissolved.
        View Details
        Q：The lyophilized form of the recombinant protein products are shipped with Blue ice and the instructions indicate that it should be stored at -80ºC.
        A：The lyophilized powder product is shipped at ambient temperature and will not be affected. Freeze-drying improves the stability of the protein product while reducing packaging materials and shipping costs. We have tested the shipping conditions of our freeze-dried products to ensure product quality.
