HCP Analysis by AAE™ and Mass Spectrometry

Antibody Affinity Extraction™ (AAE™) is a superior alternative to 2D Western blot for the determination of polyclonal anti-HCP coverage and reactivity to individual HCPs. Learn how using AAE™ with Mass Spec can help identify HCPs that often persist through the purification process.
