Huge Turnout for China Regional Workshop

Hong Kong Plexon just finished hosting its remarkably successful 2013 Regional Workshop held at the Peking University Health Science Center in Beijing. Nearly 80 attendees represented almost 40 labs!  The workshop offered three full days of instruction including expert training with OmniPlex®, CinePlex®, PlexBright, Offline Sorter, NeuroExplorer®, electrodes and animal surgery. Attendees were honored to hear from special guest speakers Dr. Wu Xujun and Dr. Xu Kedi who kindly shared a wealth of guidance and experience on topics including optogenetics.  Attendees enjoyed lecture style presentations followed by hands-on application.

Congratulations to Hong Kong Plexon and thank you to all researchers who participated! This is the largest and most successful China Regional Workshop to date!

New PlexBright™ Infrared LED Modules

Plexon is also pleased to announce the release of two new infrared (850nm and 940nm) wavelengths in our line of PlexBright™ LED Modules. Like other PlexBright LED Modules, these new infrared modules deliver levels of fiber-coupled light dramatically higher than of competitor fiber-coupled LEDs. Both infrared wavelengths are available in either the Table-top or Compact LED Module form factor.

It is important to note that when characterizing LED module output intensities, Plexon provides the most relevant specifications for optogenetics research: the amount of continuous light power delivered to tissue, rather than the full output intensity of the module.

PlexBright Dual LED Commutator Now with Magnetic Attachments

Earlier this year, Plexon launched the light-weight PlexBright Dual LED Commutator that supports up to two, uniquely engineered, compact, high-intensity LED modules. We appreciate the great wave of interest so quickly and, more importantly, the feedback from researchers’ experiences covering a wide variety of experimental set-ups. We not only confirmed that the PlexBright Dual LED Commutator functioned extremely well; but, we also gained important insight regarding improving the “interchangeability” of the Compact LED Modules.

Introducing the PlexBright Dual LED Commutator with a magnetic interface between the commutator and the LED modules! Often, a PlexBright Dual LED Commutator is fixed inside a cage or an animal environment. The new magnetic connection makes exchanging LED modules much faster and easier.
