the alcohol you're referring is due to "XYLENE removal" process just after deparrafinization...Xylene is miscible w/ absolute alcohol..so use 100% alcohol to remove xylene...then descending concentrations of alcohol..from 90-50% will add-up water from the tissue..."90"% alcohol means there is 10% water in it, 50% alcohol mean 50% alcohol and 50% water . That is where the tissue becomes hydrated..ready for staining...hope u get it.
i guess im asking randomly but does anybody know of a way to get back into an Instagram account? I was stupid forgot the account password. I would appreciate any assistance you can give me.
@Oliver Trent i really appreciate your reply. I found the site on google and im in the hacking process atm. I see it takes quite some time so I will reply here later when my account password hopefully is recovered.
@TheRealHarsjan for "Dehydration" alcohol starts from lower concentration to higher then to absolute concentration. Rationale: if tissues are submerged directly to high alcohol con. tissues will become hard or brittle, the outer portion of the tissue will dehydrated quick but the inner part is not fully dehydrated. Prior in performing H & E staining, you need to " Deparaffinize " use xylene, then remove xylene by absolute alcohol ( xylene is only miscible w/ absolute alcohol )
@DerSchnurrbart You sure don't. We use an automatic staining machine that dips slides in xylene for about 5 minutes per bath. The gradient of alcohols they use is much more long and involved than ours too. It might have something to do with the specific formulation of the stain they used, but I don't know. This seems more complicated than it has to be.
@TheRealHarsjan after removing xylene...you need remove the alcohol from the tissue and replace it with water..so that your stains will have more affinity to the tissue. how do you do this? by passing through series of high concentrations of alcohol ( starts from your absolute to remove xylene) then to 90-80-70 then finally to water...then you can start H& E staining.

@Oliver Trent It did the trick and I finally got access to my account again. I am so happy!
Thanks so much, you saved my account !
@Fabian Ryan you are welcome :D
A lot goes into this. I wonder how someone figured out the alcohol concentration quantities and times needed.
It's all based on trial & error.

this was the explanation I was looking for, thank you for taking the time to explain this concept.

why that guy didnt differentiate or blue?
How much time is minimally required to prepare H and E slide for reporting?
what is the meaning of two changes of 2 mins each?
it just try which put from PBS to absolute EtOH twice?
Why the serial dilution in organic solvents?
I don't think you need to put the slide into the xylene so long when you are deparaffinizing it.
1 hour in Xylene is a lot isn't it? 0_o We only do 6 minutes total in Florida.
histobelle may be depending on technician
@@hopehope8597 The tissue doesn't care who the technician is, but maybe the kinds of samples they work with are different
I'm just being started. Let this video be my reference point! Wish me good luck!
I know that the alcohol is used for dehydration, but why so many different types of concentration? (student :) )

may I have your protocol ? please email me to ryansaputra252@gmail.com
check my video on tissue Staining
is this Harris’s haematoxylin ?
Hello, what are the most widely used fixative in HandE staining method

Please help me answer
Formaldehyde
That procedure is too long,and I've notice in this video that no diferentiation with 0.5% HCL after hematoxylin was done.
Thanks, this helped me with my university assignment

This was...AMAZING!!!! Thanks for the vid!
Sir thankyou apke video se bahot help ho jati samjne main ese hi agge hamare liye video banate rhe
Thankyou khoob khoob thankyou
@DerSchnurrbart yes i agree.
5 min in xylene is all u need to get rid of the paraffin and just a min each in the other reagents
may I have your protocol ? please email me to ryansaputra252@gmail.com
Thankyou so much sir
Soo helpful thankss
saaai tá tudo errado
Thanku so much
Fantastic
And easier

Nope you are wrong

I don't know the most widely but I used Formaldehyde to fixed gills and stomach of fish.
