Recombinant Betula pendula BETVIA was expressed in E. coli.
When stored at -20 centigrade the quality of the material will be maintained for several years. However, for short periods (max. 3 weeks) the lyophilized product may be kept at room temperature. After reconstitution store at -20 centigrade. Avoid repeated freezing/thawing.
The material can be reconstituted with distilled water (or equivalent) or dilute buffers. The recombinant proteins can be used for ELISA or Western (users must test the optimal concentration).
