Some tips at sectioning. Remove the spec. trans light cable. Turn the Chuck not the hole Seg.Arc. and use a Trimmer with a diamond cutter. The razor blades causes defects in your diatome knife sooner or later. :-)
Yes? Because we know what each step, what each substance does to each part of our cells... For example, the one thing that isn't "frozen" by doing it this way are lipids, so there are just holes instead of them
Fixation by glutaraldehdye
Wash with optimum tetraoxide
Wash with pbs
Dehydration with ethanol
Propylene oxide
Infiltrate with resin
Embedding put resin inside a mold
Oven for overnight 60 degrees
Cut the plastic mold
Sectioning by ultramicrotome
Why did we use tetraoxide and pbs ? Whats the benefit ? Also propylene
You deserve a raise!
Thank you Ma'am for this clear explanation 😀

😘😌o god 🙏.... Awesome yar... It's just amazing.
Very useful video of ultramicrotomy sample preparation and processing. Thank you very much.
Excellent, very complicated. Thanks for sharing, enlightening us.
Very much intresting 👏👏👏
thank you for sharing very clear and interesting explanation
Wow!! Amazed. Thank you
“We are now sectioning our sample *machine beeps* oh god dang it” I felt that
can you tell me what was the specimen used in this prepration
@@ayeshairshad8681 no, they never mentioned what sample it is but my guess is tissue but looks more like plant
@@alejandratellez8848 ok thanks
can you tell me which resin to use for post embedding of plant samples? mention resin name please
Thank you mam🌺
Very Interesting and Amazing ☺👍
Very well explained
Thank you for your hardwork
wow you saveddddd my life! best video
how much time the sample should be incubated with Osmium Tetroxide
Thank you so much it was really helpful. Keep up the good work
It's more complicated than I thought :D Thank you.
Why do we add uranyl acetate first and then lead citrate?
What is that drop in which you are finally dropping the grid?
Some of the steps the voice was cut. How much time needed to keep the sample with the stain? Same thing with the last step.
hi i have a question, first at all dorry for my english!. to discard the osmiun u use a container onli for it? or u mix with the another discards? thx
10:03 What is name of blue color container having water and knife in it?
how long sample need to put osmium tetraoxide ? after stain with lead citrate then the sample can be taken for electron microscope ?
very helpful thank you so much
Good video
How do you prepare red blood cells for SEM?
Thanks a lot
do you really think this research reflects biological reality after all this processing?
Nice question
Yes?
Because we know what each step, what each substance does to each part of our cells...
For example, the one thing that isn't "frozen" by doing it this way are lipids, so there are just holes instead of them
Can be applied for TiO2 sample preparation
Thank you madam
60 degree temp incubation????
What was the resin name? please mention
Epoxy Resin....
thanks
Please what is the first staining reagent?? I heard urine acetate 🤔
Uranyl acetate
😂
