First at all, a quick reminder… Cytokines play important roles in inflammation, innate immunity, angiogenesis and cell growth. They are involved in a lot of disease processes like cancer, obesity and inflammatory and neurobiological diseases.

The RayBio® Membrane-Based Antibody Arrays (C-Series) are tools for screening and comparing expression levels of many cytokines, growth factors, proteases, soluble receptors, and other proteins in a wide variety of sample type.

After these brief definitions, today I would like to introduce you to a new tool allowing multiple cytokine detection. RayBio C-series Neurobiological Discovery Arrays will help you to measure several factors in inflammation, immunology. This method is very popular and can be used for two species: human and mouse.

In a previous post, we looked at innovative methods to assess immunogenicity in biotherapeutics and biosimilars.

The objective though, is to have the least immunogenicity possible (exception made for vaccines). Some factors, especially those which are patient-related, cannot be always controlled but some can definitely be monitored during the production processes of biotherapeutics and biosimilars. Let’s take the case of  Host Cell Proteins (HCPs).

To pool or not to pool biological samples? This question might pop up in the mind of anyone designing biomarker discovery approaches!

Much debate has been raised on biomarker discovery from clinical cohort studies, since the first experiments linking SNPs to disease phenotypes, to the current and new proteomic and miRNA technologies. The answer to this question strictly depends on clinical data, patient group characteristics and… financial means.
