TEM Kung Fu! [Jan. 25th, 2006|04:49 pm]

Hey, I just recently joined this group :D So here goes Transmission EM kung fu! Some of my work was recently published in the Plant Cell journal. My name isn't actually listed as one of the article's authors, but I did get into the Acknowledgements section for my super-fantastic sectioning. I do believe that Figure 6 is my work (plausibly some of the photos in Fig. 5, but who's counting).

Check it out at: http://thekimik.livejournal.com/4732.html

Cheers,

Hello all! I was poking around some moss bits yesterday and I found this cute little water bear. It was near the edge of the water droplet outside of the coverslip, hence the blue bits. I thought the mix of colors was nice, and I thought I'd share. :c)

Anyone have any idea what this thing could be? I found it in a bit of tissue taken from a lung resection patient.

I had to produce an SEM lab file for one of my modules and here are a few images I took for it. They're nothing special but I am still a novice :)

Hello! I'm new here, I'm a (mostly) macro photographer who recently got her hands on a nice trinocular compound light microscope! So I decided it would not be appropriate to post these types of pics to my macrophoto group :c) I thought I'd share one of my wonderful experiments with cross polarizing crystals!

Nice to meet you all!

I'll be starting my third year EM project next week and thought some of you might be interested. What I am doing is an SEM investigation of human ciliated epithelial cells. What I'm looking at specifically is the best way to image these things to avoid artefacts and image distortions.

I have some pots of human lung recovered from lung resection operations carried out in the local hospital and will be testing the effects of critical point drying, freeze drying and fully hydrated cells on a peltier cold stage in low-vacuum SEM. The aim is to find the ideal way for preparing these cells for use in further studies. The aim is to provide a good guide for studies involving abnormalties, etc, that could potentially be obscured by artefacts.

I wonder if anyone here has experience working with ciliated epithelia and might have some tips for imaging. Particularly, does anyone have any insights about what method is likely to produce the most accurate images?

The best light and fluorescent microscopes? [Nov. 4th, 2005|08:45 pm]

Dear colleagues!
What is yours favourite brand for light and fluorescent microscopy? And why? Or maybe it's indifferent?

Sadly, my contributions to this community are going to have to wait a while. I've taken some images of single-celled marine sediment dwellers but can't get them off the microscope machines until I've collected all my work for the term.

Is it just me or are the older SEMs easier to work with? Our Jeol 5200 makes much more sense than our fancier 5600LV.

My pics are quite good for a first attempt, if I do say so myself. I can't quite remember what the organisms are but they are single-celled and build massive structures around themselves of spiky mineral deposits. Nice little spheres of sponge impaled on them too.
