FAQ

What is a biosimilar?
A biosimilar is a biological product that is highly similar to an existing approved reference biological product (also known as the originator or reference product), with no clinically meaningful differences in terms of safety, purity, and potency. Biosimilars are developed to be highly similar to the reference product in terms of structure, function, pharmacokinetics, and clinical efficacy. Alpha Lifetech can provide biosimilar antibody products.

How to purify your antibodies?
Protein A/G Chromatography: Protein A and Protein G are affinity chromatography matrices that specifically bind to the Fc region of antibodies, allowing for their purification from complex mixtures.
Ion Exchange Chromatography: Ion exchange chromatography separates proteins based on their net charge at a specific pH.
Size Exclusion Chromatography: Size exclusion chromatography (SEC), also known as gel filtration chromatography, separates proteins based on their size and shape.
Affinity Tag Purification: Some recombinant antibodies are engineered with affinity tags (e.g., His-tag, FLAG-tag) that facilitate purification. Affinity tag purification involves using specific affinity resins or columns that bind to the tag, allowing for purification of the tagged antibodies. Alpha Lifetech has multiple antibody purification strategies. Please contact us via email [email protected] for more detailed information.
