This application note outlines a simple three-step method for the extraction of loperamide and its main metabolite, N-desmethyl loperamide, from blood. UCT’s Clean Screen® XCEL I column provides users with the same level of sample clean-up as traditional SPE while allowing the elimination of timely conditioning and wash steps.

Antibody-dependent cell-mediated cytotoxicity (ADCC) is a crucial mechanism of action (MoA) of anti-tumour therapeutic antibodies and FcγIIIa receptor plays a key role in this process by interacting with the N-glycans of IgG Fc regions. Hence, affinity chromatography on Fc receptor ligands can deliver valuable information about expected ADCC activity and mAb glycoform distribution.

Branching affects macroscopic polymer properties such as crystallinity, melting temperature, toughness, ductility, and optical clarity. Two types of branching are long-chain branching (LCB) and short-chain branching (SCB), wherein the molar mass of the branches is larger or smaller than the entanglement molar mass, respectively.
