What else can I help you with?
Does the hanging-drop technique have any practical value?
Yes, the hanging-drop technique is commonly used in laboratories for observing live cells or microorganisms under a microscope. It allows for the visualization of cellular behaviors and interactions in a controlled environment, making it a valuable tool in studying cell biology, microbiology, and drug discovery.
What is the purpose of hanging drop technique?
The purpose of the hanging drop technique is a method in which a drop of bacterial suspension is enclosed in an air-tight chamber prepared in a special depression slide. It allows you to view living organisms.
What is the value of a hanging-drop preparation?
A hanging-drop preparation is used in microbiology to observe the motility of microorganisms. By placing a drop of liquid culture on a coverslip inverted over a concave slide, the microorganisms are suspended in a hanging drop of liquid, allowing for easy observation under a microscope.
What is the principle behind the Hanging drop method?
The hanging drop method is based on the principle of capillary action, where a droplet of sample is suspended from an inverted cover slip on a depression slide. This method allows for observation of live cells or microorganisms in a controlled environment, enabling visualization of motility, growth, and interactions. The hanging drop technique is commonly used in microbiology and cell biology research.
Definition of hanging drop technique?
First you have to understand that the purpose of this technique is to observe living bacteria being motile. Motility is an inheritable phenotype and is critical for identification and classification of bacteria. The technique is done by applyling petroleum jelly to all sides of a cover glass. Add a water droplet and specimen using an aseptic loop onto the concave side of a depression slide. Put the jelly side of the cover glass over the droplet. View the droplet as it is suspended or "hanging" from the side. It is a "hanging drop" slide because the droplet remains untouched due to the concave shape of the cover glass and it just hangs from the cover glass.

Can flagella be seen in hanging-drop preparations?
Yes, flagella can be observed in hanging-drop preparations, although they may be challenging to see due to their thin and flexible structure. This technique allows for the examination of live, motile organisms in a drop of liquid, providing a suitable environment to visualize flagellar movement. Staining methods can enhance visibility, but in unstained preparations, flagella may still be inferred through the movement patterns of the organisms.
What is the use of hanging drop?
Hanging drop preparations can be observed for a long time because they do not dry up very quickly. Thus, motility of an organisim can be observed.
Why isn't the oil immersion lens used in hanging drop procedure?
the hanging drop procedure uses a thicker slide, which could crack if the oil immersion lens is used. My bio professor worte: hanging drop slides asre too thick to use under oil.
Purpose of the hanging drop.?
The hanging drop method is used in microbiology to grow and observe bacterial or yeast cultures. It involves suspending a drop of liquid culture from a coverslip over a depression slide. This setup allows for the observation of microbial growth in a controlled environment.
Hanging drop slide?
To make a hanging drop slide, you will need: -a depression slide -a square coverslip -some petrolatum -the liquid suspension of what you wish to view Place a small spot of petrolatum on each of the 4 corners of the coverslip. Place a drop of your suspension in the center of the coverslip. Invert a depression slide over the drop, allowing the petrolatum to attach the coverslip to the depression slide. Quickly (but carefully) invert the slide so that the coverslip is oriented "up", and the drop is hanging into the slide depression.
What is the silver line in hanging drop method?
The sliver line that you see is actually an artifact and the edge of the drop.
How does hanging cause?
Hanging as a form of capital punishment is achieved by the drop and the neck is broken. Lynching some one chokes them to death.
