gio' Bench [how it works]
Space
My Bench Space is your space on Scientist Solutions, with both a private area where you can keep track of your account settings and favorite postings, and a public area where you can upload your picture, customize your profile, or start a blog

My Summary
Keeps a log of the topics you've started, the replies you've made, protocols or events you've posted, etc. Your summary will show up in your public profile.

My Blogs
You can create as many blogs as you like. They'll be viewable by anyone who looks at your profile, and they will also be indexed and listed in The Forums section of Scientist Solutions

My Lab Drawer (private)
As you browse through Scientist Solutions, you may see a topic, event, job or protocol that you'd like to store so that you can find it again easily. By clicking the "Save to My Bench Space" button next to any item on our site, you will put that item in your lab drawer for future reference.
You can also add fellow scientists to your lab drawer by clicking the "Save this scientist to My Bench Space" link next to that member's name in their posts or Bench Space profiles.

My PubMed Alerts (private)
This really cool tool allows you to set up email notifications whenever and article in your area of interest (specified by keyword is published in PubMed

Replied to topic in Anatomy and Physiology forum   Cesium for K, but what for Na channels?

ok thanks, but still...my question remains: why are we not usually that bothered to block Na currents when measuring K currents as we are to block K when recording Na? I'm doing hERG channels, and using NaCl in the external with no concern. Is it because Na is usually negligible compared to hERG, o ...

Hi everyone, a stupid question on electrophysiology: why do we use Cs to block K channels and therefore isolate Na currents and do not do the same when studying K channels? I mean, why don't we use something to block Na channels and isolate therefore K currents? thanks g
