rAg. RECOMBINANT ANTIGENS | Operon - Inmuno & Molecular Diagnostics

Since 2000, our R+D team has been developing the techniques of recombinant protein production and purification in E.Coli bacteria During these years, OPERON has obtained diverse recombinant antigens (human tTg, MACH (Tripanosoma Cruzi), gp41 (HIV 1) and gp36 (HIV 2), ...).

We are pleased to offer the following recombinant antigens, most of which are used with great success in our diagnostic tests, and in...
