Is Giemsa Stain Flammable? 

This article will answer the question, is Giemsa stain flammable? It also covers several topics about Giemsa stain, its uses, its utilizations, how Giemsa stain can ignite a fire, and the fire handling method caused by Giemsa stain burn.

Is Giemsa Stain Flammable?

Giemsa stain is considered a very explosive material. As a result, it should be handled with great caution on any occasion.

What Is Giemsa Stain?

The term “Giemsa staining” refers to a method of microscopic staining that was initially created by Gustav Giemsa and is used in microbiology.

Red eosin, blue methylene blue, and purple methylene Azure are the three components that makeup Giemsa’s solution. Eosin is used in the Giemsa staining procedure to give erythrocytes their characteristic color.

Giemsa staining is most commonly used as a standard method for staining the plasmodium parasite, which is the causative agent of malaria. 

However, this method is also utilized in histology due to its capacity to stain chromatin, cell nuclear membranes, metachromasia, and other cell components with satisfactory quality. 

In addition, the Giemsa staining method is the fundamental approach utilized in the Kiel classification system for categorizing lymphoma cells. 

Besides, the Giemsa staining method can be used to distinguish between different types of fungus and bacteria. After being stained, the fungus hyphae will appear to have a hue that is either blue or purple when viewed through a microscope.

The Giemsa staining method is another primary method utilized for diagnosing filariasis-causing worms.

The Giemsa stain was performed by applying a few drops of Giemsa to a blood smear and letting it stand for twenty minutes before analyzing the result. 

When generating a blood smear, the objective of staining is to sharpen or clarify various cell elements, particularly the cells, so that they may be differentiated and inspected under a microscope. 

Eosin, methylene blue, and methylene azure are the three dyes combined to create Giemsa ink. The consequence of staining with a mixture of methylene azure and methylene blue will produce eosinate, which is more stable than the original stain.

The Giemsa quality test can be performed in two different ways, which are as follows: 

  • Blood cells are dyed, and then they are viewed using a microscope. The fact that Giemsa and its dilution still met all of the criteria established by the results is evidence that they are both effective.
  • Experiment with filter paper and methanol.

The filter paper should be placed on top of the glass. After placing 1-2 drops of Giemsa on filter paper and waiting for it to absorb and expand, add 100% methanol in the center of the Giemsa with a few seconds in between additions. 

Continue doing this until the diameter of the Giemsa is between 5-7 centimeters. The circle that makes the blue circle (methylene blue) can be found in the middle, a purple ring (methyl Azure) can be found on the exterior, and a thin red circle (eosin) can be located on edge.

What Are the Properties of Giemsa Stain?

Giemsa is a dye that is created using the Romanowsky principle. It is composed of Azure B, also known as the methylene blue oxidation product, which has a blue color, and eosin, which has a red color. 

Because the combination of these two dyes is iridescent, it can give blood smear preparations a variety of colors. Azure B, also known as trimethyl thionine, has a fundamental nature, whereas eosin Y is acidic. 

Azure B stains alkaline cell components like eosinophil granules and eosin Y stains alkaline cell components like eosinophil granules, the combination of eosin Y and azure B can produce a purple color when they form a connection.

What Are the Benefits of Using Giemsa Stains?

Hematological smears, bone marrow samples, and tissue sections are all areas in which clinical laboratories make extensive use of this method because it is not only straightforward to carry out but also highly functional and cost-effective.

Giemsa staining method is a highly beneficial tool for cytological research. Using this method, the cytoplasm, nuclei, nucleoli, vacuoles, and cell granules are stained, allowing the detection of minute remnants of chromatin.

Techniques for Giemsa staining are utilized in various fields, such as hematology, mycology, bacteriology, parasitology, cytology, and cytogenetics, among others.

Mycology

In this aspect, it is frequently used to examine tissue samples in the search for Histoplasma capsulatum, an intracellular dimorphic fungus.

Bacteriology

In patients who suffer from a condition known as recurrent fever, the presence of Borrelias species can be identified using a hematological smear that has been stained with Giemsa. 

Hematology

This is the function suggested for this hue the vast majority of the time. We can recognize every cell that is present in a sample of bone marrow or peripheral blood due to this technology. 

It can identify leukocytosis, leukopenia, and thrombocytopenia, among other conditions, in addition to determining the number of each series.

Parasitology

Giemsa staining is a technique that has revolutionized the study of parasitology by making it possible to diagnose parasitic disorders such as malaria, Chagas disease, and leishmaniasis.

Cytology

Giemsa staining is also utilized for cytological analyses of endocervical samples, even though this method is not the most commonly used one for carrying out cytological examinations of endocervical specimens.

Cytogenetics

The capacity of Giemsa to form strong bonds with areas of DNA that are abundant in adenine and thymine is an essential aspect of this protein. This makes it possible to see DNA in action throughout the process of cell mitosis in a variety of condensation states.

What Kinds of Firefighting Procedures Are Used to Put Out Burns on Giemsa stains?

  • Foam, water, dry extinguishing powder, and other firefighting agents should be coordinated according to the fire’s surroundings.
  • When fighting a fire, use self-contained breathing apparatus and wear all protective clothing.
  • Do not inhale fumes in the case of a fire or explosion.
  • Spray water over fire-exposed containers to keep them cool. Cool containers that have been exposed to flames using water until the fire has been extinguished.
  • If it is safe, remove containers from the fire area.
  • Firefighters must wear specified protection equipment such as a flame-resistant coat, gloves, a helmet with a face shield, and rubber boots.

Conclusion

In the presence of fire, the usage of Giemsa stain must be accompanied by a firefighting safety protocol.

Frequently Asked Question (FAQs): Is Giemsa Stain Flammable?

Is the Giemsa stain basic or acidic?

Similar to other Romanowsky stains, it is made up of both acidic and basic dyes. This is because the acidity and basicity of blood cells have different affinities for the paints. 

The blue-purple color is produced when an azure and methylene blue dye, which is a basic dye, bind to the acid nucleus.

How to get clear of the Giemsa stain?

The Giemsa stain can be eliminated by simply soaking the slide in xylene for one or two days, with the amount of time needed proportional to how dark the color is. 

It will remove the coverslip from the slide and any excess and discoloration that may be present. If the stain is still visible on the decline, you can try to remove it by soaking it in water that is lukewarm for a few minutes.
