C-terminal Src kinase (Csk) and Csk-homologous kinase (Chk) are the major endogenous inhibitors of Src-family kinases (SFKs). They employ two mechanisms to inhibit SFKs. First, they phosphorylate the C-terminal tail tyrosine which stabilizes SFKs in a closed inactive conformation by

The aim of this research was to use nucleic acids isolated from formalin-fixed paraffin-embedded (FFPE) tissue to investigate the diagnostic potential and prognostic significance of FOXL2 in adult-type GCTs, particularly as a marker of identifying early stage patients that are

Pathology archives contain vast resources of clinical material in the form of formalin-fixed paraffin-embedded (FFPE) tissue samples. Owing to the methods of tissue fixation and storage, the integrity of DNA and RNA available from FFPE tissue is compromized, which means

Painful venoms are used to deter predators. Pain itself, however, can signal damage and thus serves an important adaptive function. Evolution to reduce general pain responses, although valuable for preying on venomous species, is rare, likely because it comes with

We have produced a monoclonal antibody (PM43) selectively reactive with formalin-fixed paraffin-embedded peripheral nervous system (PNS) myelin. The hybridomas were generated by fusion of mouse myeloma cell line Sp2/0 with spleen cells of BALB/c mice immunized with cultured human melanocytes.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
