7. Application Note: Automated Assessment of Comparability for Antibody Drug Conjugates (ADCs) Using LC-UV and LC-UV/MS

Antibody Drug Conjugates (ADCs) have been emerging as a new class of anti-cancer therapeutics, combining the targeted delivery capability of a monoclonal antibody (mAb) with the potency of conjugated cytotoxic agents. By releasing the cytotoxic drugs inside target tumor cells, ADCs minimize exposure of non-target cells to toxic drug payloads and thereby reduce potential side-effects of the treatment. This application note demonstrates an integrated informatics workflow using UNIFI® Software that streamlines data acquisition, processing and reporting for ADC analysis by LC-UV or LC-MS.

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems. Find the best UHPLC and HPLC equipment in our peer reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Atomic Absorption / Emission SpectroscopyAtomic absorption spectroscopy (AAS) and atomic emission spectroscopy (AES) — also called optical emission spectroscopy (OES) — are used to detect the elemental constituents in samples. Both techniques involve the atomization of a sample. Atomic absorption spectrometers may use a flame or furnace to create an atomic vapor of the sample before irradiation with spectral light. Optical emission spectrometers may use a flame, inductively coupled plasma (ICP), microwave plasma (MP) or spark arcs to atomize and excite the sample. At higher excitation energies, electrons can be emitted instead of photons, which can be useful for samples that can’t be atomized and for surface analysis. Explore electron spectroscopy equipment such as Auger spectrometers and photoelectron spectrometers for surface elemental analysis of samples. Find the best atomic absorption, photoelectron and optical emission spectrometers in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.LC-MSLC-MS (liquid chromatography-mass spectrometry) systems and equipment are used for separation and quantitative analysis of complex mixtures, combining liquid chromatography and mass spectrometry. Quantify proteins, contaminants, pesticides or screen for drug metabolites with a high level of sensitivity. LC-MS systems and equipment include reverse phase, normal phase and specialized columns integrated with various MS detectors such as time-of-flight (TOF), quadrupole, orbitrap or ion trap mass analyzers. LC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzer give greater sensitivity and resolving power to your analysis. Find the best LC-MS equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Mass SpectrometryMass spectrometry (MS) is a powerful analytical technique used to identify and quantify molecules based on the mass-to-charge ratio of gas-phase ions. It provides detailed information about the structure, composition, and properties of compounds and is widely used across fields such as environmental monitoring, materials science, drug discovery and development, food and beverage testing, and wider chemical research. Key MS techniques include tandem mass spectrometry (MS/MS), liquid chromatography–mass spectrometry (LS-MS) and inductively coupled plasma (ICP-MS). Choosing from these wide range of techniques and technologies can be a daunting task, so keep up to date with scientific applications, performance expectations, and customer reviews here all in one place. Visit our product directory to receive quotes direct from the manufacturer. UV-Visible SpectroscopyUltraviolet-visible (UV-Vis) spectrophotometers are used to measure the interaction of UV and visible light with a sample, including transmission, reflectance & absorbance. The two major instrument classes are single-beam or double-beam spectrophotometers. More specialized equipment includes colorimeters, spectroradiometers and refractometers. Portable and microvolume spectrophotometers are also available. For the modular spectroscopy lab, explore a range of light sources for combination with a spectrograph/spectrometer and optics.
