Does anyone know where I can find a protocol for preparation of specimens via the OTOTO [osmium tetroxide-thiocarbohydrazide] method for SEM?

Hey guys-

Do any of you know where I could find labeled EM pictures of brain tissue? I just started working in a lab, and took my first picture using the EM, but I don't really know what I'm looking at...

Or if any of you have helpful ideas of things to look for, I would appreciate it... I know how to spot basic things like an axon or mitochondrion, but there are so many other blobs on my micrograph that I have no clue where to start..

Thanks!
Amber

Hello, all. I'd like to buy a student microscope for a bright 10 year old, and am willing to spend up to $200.00 (though less would be better...) I'd like to get something of decent quality, tough, and not frustrating to use. Maybe even something I (actually, my husband since I am technology-challenged) could attach a camera to. Does anyone have a recommendation? Thank you kindly in advance.

Hello all!  I'm completely new to "microscoping" and I'm considering buying a microscope right now, along with a USB video camera for use with it.  I was just wondering if anyone could give any advice, since I know very little about what is available and what is and isn't a good price.  I guess the best thing to do would be to mention the particular microscope I'm considering right now:

http://www.escience.ca/genSci/RENDER/2/1005/1014/11691.html

I'm looking at the model 30-M-100 for $399.99 Canadian.  The specs are listed below on that page, but for clarity I'll list them again here:

-Monocular Head
-10x WF/Pointer Eyepiece
-4x, 10x, 40x, and 100x (oil) Objectives
-Mechanical Stage
-1.25 Abbe Condenser
-Iris Diaphragm
-Coaxial Coarse and Fine Focusing
-20 Watt Tungsten Light* (See Below)

*You can change this for a 110 volt flourescent light for 40 dollars, or a 20 watt, 6 volt halogen light for 60.

Does this seem like A) a quality microscope, and B) worth the price of 400 Canadian?  Also, should I upgrade the light for better imaging, particularly since I want to use a camera with the microscope?

Now, here's the camera I was looking at:

http://www.escience.ca/genSci/RENDER/2/1005/1021/12686.html

I'm considering the USB 2.0 version, for $295.95 Canadian.  It does 640x480 video at 30 frames per second, which seems decent to me, though I would sort of like something that can do that plus higher resolution still images.

Again, my question is - is this a good price, for the features?  Does anyone know of anything similar that could do the same video quality plus better still imaging?

Forming my committee [Aug. 29th, 2006|07:25 pm]

How do I ask someone to be on my committee?

Do I say, "Dr. X, I'm (insert name here). I am one of Dr. Y's students. I'm forming my committee and I'd be honored if you'd be a part of it."

Sorry if this is a stupid question, but I don't know if there is some proper etiquette to this or something.

Thanks.

Does anyone here know anything about or worked with TEM tomography?

I might get to use one in the future so I figure it might be fun to connect with people for trouble-shooting, etc.
