Bacteria are everywhere, but they are too small to see with the naked eye. How can you observe and identify different types of bacteria? One of the most common and useful methods is the Gram stain, which distinguishes bacteria based on the structure of their cell walls. In this article, you will learn more about the Gram stain, how to use it, and why you should consider buying the 10pk Bacillus Smear, Gram Negative Stain – Prepared Microscope Slides from Eisco Labs.
What is the Gram stain?
The Gram stain is a technique that involves staining bacteria with two different dyes: crystal violet and safranin. The bacteria are first fixed on a glass slide, then treated with crystal violet, which binds to the cell wall. Next, the slide is washed with a solution of iodine and alcohol, which acts as a mordant and a decolorizer. The iodine enhances the binding of crystal violet, while the alcohol dissolves the outer membrane of some bacteria. Finally, the slide is counterstained with safranin, which colors the bacteria that lost the crystal violet.
The result is that bacteria can be divided into two groups: Gram-positive and Gram-negative. Gram-positive bacteria have a thick layer of peptidoglycan in their cell wall, which retains the crystal violet and appears purple under the microscope. Gram-negative bacteria have a thin layer of peptidoglycan and an outer membrane, which is dissolved by the alcohol and loses the crystal violet. They appear pink or red after being stained with safranin.
The Gram stain is important because it helps to identify and classify bacteria based on their morphology and physiology. It also provides clues about the susceptibility of bacteria to antibiotics, since Gram-positive and Gram-negative bacteria have different cell wall structures and permeability.
How to use the 10pk Bacillus Smear, Gram Negative Stain – Prepared Microscope Slides
If you want to study bacteria with the Gram stain, you will need a microscope, a light source, and prepared slides. You can prepare your own slides by collecting samples of bacteria from different sources, such as soil, water, food, or your own body. However, this process can be time-consuming, messy, and potentially hazardous. You will also need to follow strict safety protocols to avoid contamination and infection.
A more convenient and reliable option is to buy prepared slides from a reputable company, such as Eisco Labs. Eisco Labs is a leading manufacturer of high-quality laboratory equipment and educational materials, with over 50 years of experience in the field. They offer a wide range of prepared microscope slides, covering various topics in biology, microbiology, histology, and pathology.
One of their best-selling products is the 10pk Bacillus Smear, Gram Negative Stain – Prepared Microscope Slides, which contains 10 slides of Gram-negative Bacillus bacteria. Bacillus is a genus of rod-shaped bacteria that can be found in various environments, such as soil, water, plants, and animals. Some species of Bacillus are beneficial, such as Bacillus subtilis, which is used as a probiotic and a model organism for research. Other species are harmful, such as Bacillus anthracis, which causes anthrax, a deadly disease.
The 10pk Bacillus Smear, Gram Negative Stain – Prepared Microscope Slides are ideal for studying the morphology and diversity of Bacillus bacteria. Each slide measures 75 x 25 mm and is made of high-quality glass. The slides are expertly prepared and labeled for easy identification. The bacteria are whole-mounted and stained with carbolfuchsin, which gives them a fuchsia color. The slides come in a polystyrene storage box, which protects them from damage and dust.
To use the slides, you simply need to place them on the microscope stage, adjust the focus and illumination, and observe the bacteria under different magnifications. You will be able to see the shape, size, arrangement, and staining of the bacteria, and compare them with other types of bacteria. You will also be able to learn more about the biology and ecology of Bacillus bacteria, and how they affect human health and the environment.
