Polyvalent polyspecific recombinant proteins and antibodies
Using our proprietary technology based on the use of uteroglobin, we offer custom polyvalent polyspecific recombinant proteins production including antibodies, immunocytokines, receptors etc.. The use of uteroglobin increases solubility and stability of fusion proteins.
We offer a full range of manufacturing services including gene synthesis, cloning, pilot expression and optimization of purification process, analysis of immunological and biological activities as well as preclinical studies.
Purified tenascins-c and fibronectins from different sources
Sirius-biotech offers preparations human tenascin-c and fibronectin purified from different sources, including plasma and normal or malignantly transformed cells as well as different recombinant fragments of both proteins.
Fibronectin (FN) is a modular glycoprotein present in plasma in a soluble form and in the extracellular matrix as insoluble form. FN is involved in many cellular processes, including tissue repair, embryogenesis, blood clotting, and cell migration/adhesion.
Tenascin-C (TN-C) is a disulfide-bonded hexamer composed of subunits with molecular weights in the range of 220-300kD, depending on the expression of different isoforms. The subunits contain EGF-ike and FN-like repeats. TN-C is abundant in the extracellular matrix of developing vertrebrate embryos and it reappears during healing wounds and in the stroma of many tumours.
