IF2D1 Tag

FineTest develops pET28a-IF2D1 expression vector with the powerful fusion tag, which perfectly replaces GST, MBP etc. Furthermore, the molecular weight is lower and the influence on the expression of target proteins is less. Thrombin functions as the enzyme cutting site to facilitate the subsequent cutting.

IF2D1 Tag

HEK293 Cell Expression System

Besides common E.Coli expression system, FineTest also developed HEK293 cell eukaryotic expression system, which can make expressed proteins more naturally active. Meanwhile, with rich expression experience, our R&D team can customize various protein sequences according to experimental requirements of customers.


P2750 Recombinant CD147 SDS-PAGE Vs P2755 Recombinant Human ACE2 SDS-PAGE

ELISA validation

We conduct the ELISA validation comparison between P2750 FineTest recombinant CD147 and 972-EMN R&D recombinant CD147. The results show FineTest eukaryotic proteins achieve the leading industrial level.
