Free Control Slides

Histology Control Slides

Beginning this week, all 22ct histology control slides (see link below) bought will now come with 3 extra unstained slides FREE. Buy 22 get 25 controls.
Histology Control Slides

We have 24 different human histology control types to choose. Mouse and rat normal tissues are also available as control slide sets (inquire). Some controls like Fite, fungus, gram and helicobacter pylori are four of our most popular controls. They go fast, get them before they’re gone!

This promotion (3 free slides) will be species specific but not necessarily same tissue type. We will try to match same controls as bought but if they are not available, we will throw in another validated control type. If you order hospital grade human tissues you will get 3 similar unstained slides, free. Likewise, if you order Mouse or Rat 22ct, you will get 3 free mouse or rat slides respectively.

Extra slides will be marked with either our slide printer or hand written. Extra slides may or may not be sequentially ordered and will be placed at the back of each box.

Free slides are not guaranteed and will discontinue at anytime. 100ct boxes not included in the promotion.

Identification of Fungus

Mycology, the study of fungus is not something I know too much about especially when it comes to histopathology.  I do know that fungus is not something I want propagating in my organs or tissues in serious quantity.  Certain species can wreak havoc on the internal and external systems of the animal bodies.  The identification of these fungi in tissues is visualized by staining with GMS, PAS and Gridley’s.  The stain fungi are then analyzed under the microscope by a pathologist who determines by size, shape and surrounding tissue changes, what the type of fungus is.  This is a very exact science that takes years of practice and studying to determine a possible diagnosis.  Some histologists may be able to guess at the type of fungus on a slide but only guess.  For a histologist must rely on the shape and color of a fungus determined by the stain.  I do this on a consistent basis, trying to guess what kind of affliction the tissue reveals after staining.  For fungus identification, I have been relying on a website called doctorfungus.  Here I can analyze my slides against a good knowledge base and slides to match.  Thus I feel like sharing this resource with you might help.
