Excellgen's scientists have average of 15 years experience in molecular biology, protein expression and purification. Our team is proficient in molecular cloning, producing and purifying of recombinant proteins in a variety of expression systems including cell-free protein synthesis,  E. Coli, yeasts, baculovirus/insect cells and mammalian cells (CHO and 293). We have AKTAExplore and AKTAPurifier FPLC systems,  ~ 30 large GE Pharmacia prepacked columns (gel filtration, hydrophobic, ion exchange,  desalting) and numerous affinity columns. By combining state-of-the-art fementation and AKTA FPLC chromatography systems, we can produce quantities of pure recombinant proteins ranging from miligrams to a few grams. Excellgen is different from some protein service companies as we do not outsource your projects to foreign countries.

We offer the following professional services:

• Custom Protein Purification Services using GE Pharmacia Akta FPLC Systems

• Protein Expression and Purification using Bacterial Expression System

• Protein Expression and Purification using Yeast Expression System

• Protein Expression and Purification using Baculovirus Expression System

• Protein Production by Cell-Free Protein Synthesis

• Transient Gene Expression and Protein Production using 293 and CHO Cells

• Protein Expression using Stable Mammalian Cell Line
