Photoentrainment and Pupillary Light Reflex Are Mediated By Distinct Populations of Iprgcs. Chen SK, Badea TC, Hattar S. Nature 476(7358):92-95, 2011. PMID: 21765429 Intinsically photosensitive retinal ganglion cells (ipRGCs) express the photopigment Melanopsin and regulate a wide array of light dependent physiological processes. Genetic ablation of ipRGCs eliminates circadian photoentrainment and severely disrupts the pupillary […]
Somasundaram et al. C-terminal phosphorylation regulates the kinetics of a subset of melanopsin-mediated behaviors in mice. PNAS (2017), pii: 201611893. PMID: 28223508 Chronotype (morningness-eveningness) in mammals likely has multiple causes. Phase angle of entrainment is defined as the relationship between the timing of the biological clock and the timing of an external time cue, and if the primary […]
Advanced Targeting Systems offers a full line of antibodies to neurotransmitters; everything from serotonin and L-DOPA, to noradrenaline and dopamine. These antibodies are an excellent choice for immunohistochemistry applications as they are ideally primed for use in tissues that have been perfused with a mixture of paraformaldehyde and gluteraldehyde. Some frequently asked questions: Q: Could you […]
Lecrux et al. Impact of altered cholinergic tones on the neurovascular coupling response to whisker stimulation. Journal of Neuroscience (2017), 1784-16. PMID: 28069927 Brain imaging techniques that use vascular signals to map changes in neuronal activity rely on the coupling between electrophysiology and hemodynamics, a phenomenon referred to “neurovascular coupling” (NVC). It is unknown whether […]
Contributed by Patrick Shramm, Product Manager for Fab-pHast We are pleased to announce a new set of tools to rapidly screen antibodies, Fab-pHast conjugates. The ATS pHAST product line provides the FASTEST results in quantitative testing of your antibody’s specific-binding and internalization. Fab-pHast contains a pH-dependent fluorescent reporter that increases intensity in acidic surroundings, such […]
