Affinity Capture Elution (ACE) ELISA Method Development and Validation for Novel RPH-104 Drug Immunogenicity Evaluation.

As the number of therapeutic protein products is growing rapidly, there is a strong need for the development of bioanalytical methods that are easy to perform, specific, sensitive, robust, and affordable. Methods for immunogenicity evaluation of therapeutic proteins take an important place in this field of bioanalytics. The aim of the study was to develop a method for immunogenicity testing of the novel RPH-104 drug using the Affinity Capture Elution (ACE) ELISA technique.

Production of biomedical cell products: requirements for the quality of donor material and excipients of animal origin (review).

Donor biological materials and excipients of animal origin are important components in the production of biomedical cell products (BMCPs). Their quality ensures the stability, safety, effectiveness and purity of the final product. This review discusses quality requirements for biological excipients intended for the production of biomedical cell products, in terms of the necessary information that should be included in the BMCP registration dossier during state registration and is subject to expert assessment during quality control.

Lipidomic analysis as a tool for identifying susceptibility to various skin diseases.

This review is about the significance of the use of lipidomic analysis for identifying susceptibility to skin diseases. Exactly this article describes the use of lipidomic analysis in different studies to detect abnormalities in the lipid composition of the skin to diagnose and prevent various dermatological diseases.

An improved extraction protocol for therapeutic dabigatran monitoring using HPLC-MS/MS.

A new sample extraction protocol was developed for pharmacokinetic studies of dabigatran with high-performance liquid chromatography separation - electrospray ionization time-of-flight mass spectrometry analysis. After protein precipitation with acetonitrile, free dabigatran and its metabolites are separated into water phase by water-dichloromethane liquid-liquid extraction to purify the sample from proteins and endogenous lipophilic compounds. Chromatographic separation was achieved on an Agilent Zorbax SB-CN column (150 × 4.
