Welcome to Two Sigma's Cook Scheduler! What is Cook? Cook is a powerful batch scheduler, specifically designed to provide a great user experience when there are more jobs to run than your cluster has capacity for. Cook is able to intelligently preempt jobs to ensure that no user ever needs...
All chemicals were from Sigma, Hello Bio or Tocris. Whole-cell electrophysiology Whole-cell recordings were made from hippocampal pyramidal neurons retrogradely labelled with retrobeads or CTXβ, which were identified by their fluorescent cell bodies and targeted with Dodt contrast microscopy, as ...
(Sigma) as described previously [70], and the same reaction times were given for antisense and sense probes. The images were obtained using an Eclipse 600 fluorescence microscope equipped with a DP70 CCD camera and a 10 × (NA 0.45) or 20 × (NA 0.50) objective lens. The ...
Sections were washed with 1.5 M urea/1 × saline sodium citrate (SSC) at 45°C for 30 min, 2 × SSC at 45°C for 15 min, treated with either antidigoxigenin-rhodamine antibody (Sigma) or avidin conjugated-fluorescein isothiocyanate (Vector Laboratories, Burlingame, USA) at 37°C ...
