What is the purpose of prolonged application of heat on the smear?
by application of heat and a mordant, the cell can be stained. the purpose of heating is to soften the waxy material of the cell wall and allow the stain enter the cell. rock on University of Luzon!
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 😊
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 must smear on the slide be completely dry before heat fixation?
Slight heating helps in fixing the cells on to the surface of the glass slide
What is the definition of negative staining?
negative staining is when the micro-organism on slide is not stained.. instead the rest of the material on the slide gets stained and the organism stands out prominently unstained.. this occurs because that organism has a thick capsule around it which is non-stainable with that stain.. example is pneumococci staining with India ink.
Purpose of fixing the bacterial film?
The purpose of heat fixing the bacteria to the slide is so during the gram staining procedure the bacteria doesn't wash off. If you didn't heat fix the bacteria to the slide, it would not stay on the slide.
What is the purpose of heat fixing the smears?
It helps the cells adhere to the slide so that they can be stained. The purpose of heat fixing is to kill the organisms without serious distortion. They adhere better to the slide and also take up dye more easily.
What is the purpose of a coverslip on a microscope?
Coverslip is not placed on a microscope but on the stained specimen on slide . This protects objective lens of microscope from getting stain from a wet mount . It also protects permanent slide .
What is fixing?
a heat fix is something you put on the slide
What is Passing a slide sample through a flame is called?
heat fixing
What is the best way to hold the upper slide when using it to spread the inoculum across the slide being stained?
At a 45 degree angle
Does Heat fixing sterilize slide?
I guess so, and that's why you put out the flame after that.

What would happen if no 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 the purpose of a point?
Purpose of power point is to create a slide. A slide is a presentation for a business meeting or group.
