Characterisation and controlled drug release from a novel two-phase hydrogel system
In this work, a two-phase hydrogel system was prepared by physically imbedding a xerogel in the core of a cryogel which was freeze thawed. The cryogels were prepared with poly (vinyl alcohol) (PVA) and poly (acrylic acid) (PAA) while the xerogels were prepared by UV polymerisation of 1-vinyl-2-pyrrolidinone (NVP), acrylic acid (AA) and various percentages of ibuprofen sodium salt. Mechanical and ...

Measurement of Elemental Impurities in a Higher Daily Dose Drug Product by USP <232>/<233> Using Ultrasonic Nebulization with ICP-AES Detection
Abstract: On January 1, 2018 the U.S. Pharmacopeia (USP) enacted new criteria for element impurities in finished drug products. These criteria, detailed in USP/, recommend analysis of drug products for element impurities by either ICP-AES or ICP-MS. Laboratories must measure impurities based on a J value for each drug product; drug products may be oral, parenteral (ex. intravenous, injection), or ...

What Is Drug Stability Analysis? - Basics You Need to Know in Drug Discovery
The basic requirements of pharmaceutical preparations are safety, efficacy, and stability. Drug stability means that a drug product should maintain the same properties and characteristics as it was at the time of production and within the specified time frame. The stability of pharmaceutical preparations directly affects the effectiveness and safety of drugs. Therefore, it is of great ...

Analysis of Opioids Using Isotope Dilution with GCMS-TQ8030 GC/MS/MS
Development of methods for analysis of drugs of abuse has become a high priority for both forensic toxicology and law enforcement. The large numbers of individual drugs and new "designer drugs" has made method development for these compounds a significant undertaking. Gas chromatography mass spectrometry (GCMS) has been used extensively for analysis of drug residues and trace-level drugs in ...

Analysis of drugs of abuse and explosives using GC-MS to compare results when using helium and hydrogen
Background Researchers from Prof. Guido Verbeck’s group at the University of North Texas (UNT) carried out analysis of drugs of abuse (DOA) and explosives using an ion trap GC-MS to compare results when using helium and hydrogen carrier and buffer gas. As well as comparing the two gases, the group also assessed a number of ion volumes with different orifice diameters to look at their ...

Cytokines: Characteristics, Applications, and Quantitative Analysis
Cytokines represent a class of small protein molecules that exhibit diverse biological activities. These molecules are synthesized and secreted primarily by immune cells (including monocytes, macrophages, T cells, B cells, and NK cells) as well as certain non-immune cells (such as endothelial cells, epidermal cells, and fibroblasts) upon specific stimulation. Cytokines play pivotal roles in ...

Biotin PEG
What are Biotinylation and Biotinylated PEG?Biotinylation is the process of covalently attaching biotin to molecules (such as amino acids, peptides, antibodies, or proteins). Due to the small molecular weight of biotin, biotinylation is usually rapid and specific and is unlikely to interfere with the inherent function of the molecule. Biotin has extremely high affinity, rapidity and high ...

Clonality Analysis Service: A Paradigm Shift in Disease Diagnosis and Treatment
Understanding Clonality Analysis Clonality refers to the origin of a cell population from a single 'parent' or progenitor cell through asexual reproduction or division. This concept is vital in cancer studies as it helps track the development of tumor cells from a single mutated cell. Clonality analysis is thus essential in understanding the evolution and the spread of cancerous cells in a ...
