Introduction of Fecal Occult Blood Test Fecal Occult Blood Testing (FOBT) has been a crucial tool in identifying gastrointestinal problems, especially colorectal cancer. However, traditional FOBT methods have their drawbacks, like being not very sensitive and having issues with color stability. In this blog, we’ll explore the Baso OB test, an improved version that tackles …
Principle of Bacterial Capsule Stain Bacterial capsules represent a unique mucous substance formed externally but intimately associated with the cell wall throughout the bacterial life cycle. These capsules play a critical role in shielding bacteria from phagocytosis, the process by which the host’s immune cells engulf and digest them. Identifying these capsules requires specialized staining …
Principle of Flagella Stain Flagella Staining is predicated on the principle of intensifying the visibility of bacterial flagella through thickening and coloring. This method enables the observation of their presence, quantity, and location, all of which are indispensable factors in the differentiation of various bacterial species. Although electron microscopes can also be employed for flagella …
Principle Cryptococcus neoformans is characterized by its distinctive mucopolysaccharide capsules enveloping the fungal cells. These capsules are a defining characteristic used for identification. The Indian ink wet-sheet method is a reliable technique for visualizing these capsules. In this method, the decidua of Cryptococcus neoformans effectively replaces colloidal carbon particles in the ink, resulting in a …
Introduction The Kinyoun stain is a fundamental technique in microbiology, used to identify acid-fast bacteria like Mycobacterium tuberculosis and Mycobacterium leprae. This staining method is based on the Ziehl-Neelsen stain recommended by the WHO. Principles of Kinyoun Stain The Kinyoun stain’s principle lies in its use of carbolfuchsin solution, which contains carbolfuchsin and phenol. Acid-fast …
Introduction The Ziehl Neelsen Acid-Fast Stain is a vital microbiological technique used to identify acid-fast bacteria, including well-known pathogens like Mycobacterium tuberculosis and Mycobacterium leprae. In this blog, we will explore the fundamental principles of this staining method, its main components, sample requirements, test procedure, result interpretation, limitations, and necessary precautions. Principle of Ziehl Neelsen …
Introduction: The Gram stain technique, initially developed by Danish physician Hans Christian Gram in 1884, has played a pivotal role in microbiology. This method allows for the categorization of bacteria into two primary groups: Gram-positive and Gram-negative, based on their distinctive cell wall characteristics. This blog post will explore the fundamental principles, key components, step-by-step …
1. Principle of α-Naphthyl Butyrate Esterase Stain α-Naphthyl Butyrate Esterase Stain, also known as α-NBE stain, is a method used to detect the presence of esterases within cells. Esterases are enzymes that catalyze the hydrolysis of ester bonds. In this staining technique, the α-Naphthyl Butyrate substrate is hydrolyzed by esterases under alkaline conditions, leading to …
Introduction Histological staining techniques have revolutionized our understanding of cellular processes, and the α-Naphthyl Acetate Esterase (α-NAE) stain holds a significant place in this field. This staining method, which reveals esterase distribution within cells, plays a crucial role in diagnostics and research. In this article, we will delve into the core principles of α-NAE staining, …
Introduction Iron stain is a vital technique used in the examination of bone marrow smears. It permits us to picture iron stores inside cells and tissues, giving fundamental bits of knowledge about different ailments. In this blog, we’ll dive into the standards behind iron staining, the parts expected for the staining methodology, the means in …
We are pleased to introduce ourselves as a trading company very actively engaged since 1987 in the sale of chemicals/reagents/glassware real-time PCR/life science and other related supplies both on ex-stock and fob/c&f through overseas principals.
