Detergents typically present in cell lysis buffers are thought to disrupt organelles and compartments and increase the exposure of soluble phospho-proteins to phosphatases and proteases thereby resulting in uncontrolled dephosphorylation and proteolysis. <br /><br />Phospho-Sure RTD Neuronal extraction buffer is optimized for the extraction of phosphorylated proteins from neuronal and other soft tissues types. The buffer extracts the phosphoproteins in a native state without the use of harsh detergents or oxidizers, and it is specially formulated to help maintain phosphoproteins and protect them from degradation better than traditional detergent based extraction buffers.

Black-Gold II is a novel haloaurophosphate complex which localises myelin within the central nervous system. The Black Gold II Ready-to-Dilute (RTD) Staining Kit allows you to localise myelin, both individual fibres and tracts, along with the option of co-localising cell bodies via the Toluidine Blue counter stain. Black Gold II labelled myelinated fibres appear nearly black while the Toluidine Blue O labelled cellular Nissl bodies are blue under bright field illumination.<br /><br />Black Gold II can demonstrate and characterise specific myelin changes associated with exposure to diverse neurotoxicants including kainic acid, domoic acid, 3-nitropropionic acid, Fluoro-Gold and isoniazid. Black Gold II can also be combined with other histochemical markers including Nissl stains, retrogradely transported fluorescent tracers and fluorescent markers of neuronal degeneration. The advantages associated with the Black-Gold II include high resolution, high contrast, short histochemical process

The causes and effects of neuronal degeneration are of major interest to a wide variety of neuroscientists. Paralleling this growing interest is an increasing number of methods applicable to the detection of neuronal degeneration. The fluorescent dye Fluoro-Jade B (FJB), like its more purified brother Fluoro-Jade C (FJC), is an anionic fluorescein derivative useful for the histological staining of neurons undergoing degeneration. Fluoro-Jade B differs from FJC in that it is a slightly less refined chemical formulation and thus it does not quite provide the same level of signal to noise or high resolution as FJC. Nonetheless FJB is still widely used and works very well as a marker of degenerating neurons and even glia (see Damjanac M et al., <a href="https://pubmed.ncbi.nlm.nih.gov/17125750/" target="_blank"><em>Brain Res.</em></a> 2007;1128(1):40-9). FJB operates nearly identically in protocol to that of FJC, and Fluoro-Jade B is compatible with several other labeling procedures includ

The Biosensis AG-400-AG kit utilizes an ethidium bromide counter stain for a quick and effective way to visualize cell nuclei and cell bodies of cells while under UV illumination allowing the assessment of amyloid plaques and cell/tissue positioning as well in one step.<br /><br />Amylo-Glo RTD Ready to Dilute Staining reagent is designed to stain amyloid plaques in tissue sections. This novel marker has several advantages over other conventional markers such as Thioflavin S and Congo Red because of its unique chemical and spectral properties. (L. Schmued et al. (2012) J.Neuroscience Methods 209:120- 126). Using Amylo-Glo results in a very bright blue UV excitable stain under physiological conditions that will not bleed through when illuminated with other filters. Its brightness makes it ideal for low magnification quantification studies, while its unique excitation/emission profile and mild staining conditions makes it ideal for combination for multiple immunofluorescent labeling stud
