What is a cytospin used for?
A cytocentrifuge, sometimes referred to as a cytospin, is a specialized centrifuge used to concentrate cells in fluid specimens onto a microscope slide so that they can be stained and examined.
What is the principle of a Cytocentrifuge?
The principle of all cytocentrifugation techniques is that the cell is denser than the suspending fluid and under an applied force the cell will have greater momentum than the fluid. The cellular movement occurs after passing through the sample chamber.
What is cytospin in histopathology?
A cytospin is obtained by employing centrifugal force to isolate, concentrate and deposit a monolayer of cells from a dilute cell suspension onto a circular area on a slide. The objective is to keep cells intact enabling the morphology of the cells to be examined.
How do you store a cytospin slide?
The cytospin slides for IHC can be stored theoretically for indefinite time for IHC. The most important factor is FIXATION AND PREVENTING smears from getting dry. For storage longer than an year , they can be fixed with methanol and kept at 4-8 degrees for as long as 2 to 3 years.
How are cells stained and slides prepared?
How Are Cells Stained and Slides Prepared?
- Permeabilization – treatment of cells, generally with a mild surfactant, which dissolves cell membranes in order to allow larger dye molecules to enter inside the cell.
- Fixation – serves to “fix” or preserve cell or tissue morphology through the preparation process.
How many cells does cytospin have?
Cytospin Protocol. Wash 105 cells in cold 2% FCS-PBS twice and dilute in 100 l of cold 1% BSA-PBS. Be sure to keep all samples on ice.
How do you store Cytospins?
What is slide staining?
Microscope Slide Staining Information. Microscope cell staining is a technique used to enable better visualization of cells and cell parts under the microscope. By using different stains, a nucleus or a cell wall are easier to view.
How do you prepare slides?
To prepare the slide:
- Place a drop of fluid in the center of the slide.
- Position sample on liquid, using tweezers.
- At an angle, place one side of the cover slip against the slide making contact with outer edge of the liquid drop.
- Lower the cover slowly, avoiding air bubbles.
- Remove excess water with the paper towel.
What is slide stainer?
About. Automated Slide stainers are devices that automate the staining of peripheral blood and other hematologic smears to facilitate laboratory microscope differential counts using Wright’s stain, a Romanowsky stain. The operator inserts slides into a carrier and selects a time or programmed procedure.
What are the important things to remember in slide preparation?

What are Autostainers?
Autostainers work on 1 of 2 principles: Either the stainer (1) dips the slides into the stain or (2) applies the stain to the slides. Stainers That Dip the Slide. Stainers that dip the slide into the stain (bath stain- ers) can be of either linear or batch design. Linear.
