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.

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.

@Fabian Ryan you are welcome :D

How much time is minimally required to prepare H and E slide for reporting?

This was...AMAZING!!!! Thanks for the vid!

I'm just being started. Let this video be my reference point! Wish me good luck!

Why the serial dilution in organic solvents?

why that guy didnt differentiate or blue?

@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.

Thanks, this helped me with my university assignment

is this Harris’s haematoxylin ?

what is the meaning of two changes of 2 mins each? it just try which put from PBS to absolute EtOH twice?

I know that the alcohol is used for dehydration, but why so many different types of concentration? (student :) )

@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 )

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

I don't think you need to put the slide into the xylene so long when you are deparaffinizing it.

Thankyou so much sir

Soo helpful thankss

@DerSchnurrbart yes i agree.

Thanku so much

@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.

check my video on tissue Staining

That procedure is too long,and I've notice in this video that no diferentiation with 0.5% HCL after hematoxylin was done.

1 hour in Xylene is a lot isn't it? 0_o We only do 6 minutes total in Florida.
