Supply Of Therapeutic Brokers By Intracerebroventricular (ICV) And Intravenous (IV) Injection In
Mice
Despite the protective position that blood mind barrier performs in shielding the mind, it limits the
access to the central nervous system (CNS) which most frequently results in failure of potential
therapeutics designed for neurodegenerative issues 1,2. Place the needle diagonally within the
microcentrifuge tube containing the injection resolution. Load the injection solution into the needle
by carefully pulling the plunger of the syringe. ICV injection: The brain will be harvested at totally
different time points put up-injection and visualized to demonstrate profitable injection technique. If
the dye just isn't added to the injection resolution, will probably be troublesome to examine for the
accuracy of the injection. In this case, the depth of the needle was not ample and the injection
solution has in all probability distributed beneath the skin. IV injection: Accurate and efficient
temporal/facial vein injection will be visualized instantly following the
Moreover, altered pores and skin color of the mouse will probably be observed following injection.
For simple visualization of injection and through a observe interval, a 1:50 dilution is recommended.
An inaccurate injection will outcome within the accumulation of inexperienced dye below the skin on
the website of the injection. A) Schematic of injection websites utilized in I.C.V. injections into the
ventricles. B) Brain from I.C.V. injected Pup with trypan blue in PBS on left ventricle, picture taken
quarter-hour submit injection.
C) Mind from I.C.V. injected Pup with trypan blue in PBS on left ventricle, picture taken 60 minutes
publish injection. B) Pup injected I.V. with inexperienced dye in PBS compared to un-injected
littermate, Photograph taken immediately submit injection. In this video, we demonstrate the step-by
step procedures involving two forms Innovation and capability voucher of injection strategies that
can be used to focus on the CNS: 1) direct injection into the CNS using intracerebroventricular (ICV)
injection; or 2) IV injection targeting the temporal/facial vein.
