Large Molecule LC (Bio LC)

Large Molecule LC (Bio LC) | Avantor

The separation of active ingredients that have been manufactured using biological processes often requires a different approach. Multiple chromatographic techniques are employed to fully characterize these complex biomolecules. Due to their size and nature, they are inherently more difficult to separate. Monoclonal antibodies, antibody-drug conjugates and some peptides require different techniques and a different approach when it comes to separation. Luckily, products from Avantor® can help.

Large Molecule LC (Bio LC) Products

HIC400-495ab.jpg

HIC is an excellent technique for the separation of proteins without causing denaturing, therefore scalable from analytical to downstream processing.

SEC400-495ab.jpg

SEC is used to separate components according to their molecular size. It is non-adsorbtive meaning no chemical interaction and leaves proteins in their native form.

Ion-Exchang--Columns400-495a.jpg

Ion exchange separates on the basis of charge on the molecule. It is often used for the separation of charge variants of peptides, proteins and oligonucleotides.

Widepore-Reversed-Phase-HPLC400-495a.jpg

A U/HPLC column with 300Å pore size (or larger) and a C4 or C8 ligand is suitable for small proteins and large peptides. Proteins are retained by adsorbtion of the hydrophobic foot.

Chromatograph400-495.jpg

If you are looking for a reliable range of chromatographic media, manufactured under cGMP conditions that can fulfill your needs from lab to production scale, Avantor® has a wide choice.

AkTA-Start400-495.jpg

If you need to improve efficiency in your laboratory protein purification, instrumentation and software could help you achieve your goal.
