How to select Hyaluronic Acid (HA) quantitative tests?
Hyaluronic acid (also called HA or Hyaluronan) is a glycosaminoglycan with unique characteristics. HA possesses elevated viscosity, enabling tissues (eye, skin, joint and synovial fluid...) to resist
Primary cell sourcing: Cryopreserved Human Adult Sebocytes
Sebocytes are emerging cellular models to study skin biology but also to design new compounds to regulate acne, seborrhoea and other sebaceous gland-related diseases. Easy access to cryopreserved and well-qualified
Modulate hepatic inflammation
Kupffer cells are macrophages endogenous to the liver which have the ability to modulate hepatic inflammation and injury associated with various pathophysiologies and toxicities. Pro-inflammatory cytokines
Human Primary Sebocyte assay for compound testing on lipid metabolism
Sebocytes belong to the epidermal ecosystem together with hair follicules or in sebaceous glands. Sebocytes play a key role in skin health by producing sebum. These cells are now at the center of researchers'
Sircol for soluble and insoluble collagen assays!
Measuring soluble collagen in biological samples is a straightforward experiment which can be done with the Sircol
MDR1 activity enhancement reduces senescence markers
During the last International Federation of Societies of Cosmetic Chemists (IFSCC) congress (Paris, Oct. 2014), Hajem N. et al (ALES Groupe) have shown that by enhancing MDR activity of fibroblasts
Predicting CYP induction in stable cell lines
Assessing gene transcription as an endpoint for determining induction of drug metabolizing enzymes and transporters has become the “method of choice” in the FDA’s latest draft Guidance for Industry drug
Easy and sensitive methods to measure antioxidative potential
Free radicals and reactive oxygen species (ROS) are highly reactive molecules that are generated by normal cellular processes, environmental stress, and UV irradiation. ROS react with cellular components,
Antibiotics and microbial metabolites - revisited
What are metabolites?
Microorganisms live in a world of chemical signals. They use small molecular weight compounds, known as metabolites, to regulate their own growth and development,
Hepatic Cellular Models
A wide range of in vitro models are used in preclinical drug testing for the investigation of ADME-Tox (Absorption, Distribution, Metabolism, Excretion and oxicity) properties of New Chemical
How to measure Glycosaminoglycans and Proteoglycans?
Glycosaminoglycans (or mucopolysaccharides) are long un-branched polysaccherides which consist of disaccharide repeats. The repeats usually (with the exception of Keratan sulfate) consist of on
