Heat fixation is the procedure used to adhere a bacterial smear to a glass slide for viewing by a compound microscope. It denatures the proteins on the surface of the bacteria causing them to be sticky.

∙ 14y agoHeat fixation is to denature the bacteria and stick it to the slide. Think cooking an egg and forgetting to spray down the surface. Without that oil, the egg sticks, like the bacteria.

What are the advantage and disadvantage of heat fixing?
adv..... heat fixing inactivates enzymes that would normally disrupt cell morphology and structure during staining and observation. dis....... if not done well much of the specimen can be destroyed in heat fixing.
What would happen if no heat fixing were done?
If no heat fixing was done to a slide with a specimen on it, it would be rinsed off with the gram staining procedure. Heat fixing the specimen does kill specimen but it also locks it in place.
What is Passing a slide sample through a flame is called?
heat fixing
Does Heat fixing sterilize slide?
I guess so, and that's why you put out the flame after that.
What effect does heat fixing have on bacterial cell size?
it makes cell size shrink

What will happen if too much heat is applied while heat fixing a slide?
When too much heat is applied during the heat fixing of a slide with a bacterial cell on it, the cell would explode. The membrane of the cell would rupture.

Why is the slide not heat fixed before negative staining?
First and foremost, the purpose of heat fixing is to drive stain into the bacterial cells, which in this case, you are staining the background, so there is not a need for heat fixing. Next, the process of heat fixing will shrink the cell by a little. This sorts of support the first reason as since there isn't the need to heat fix, then don't. By not heat-fixing, we actually see a more accurate morphology, arrangement and size of thr bacterial cell. Hope that my answers helps 😊
