MacConkey Agar is a selective and differential culture medium used in microbiology to isolate and differentiate Gram-negative bacteria, particularly those that are part of the Enterobacteriaceae family

MacConkey Agar Base is a dehydrated culture medium formulated for the selective isolation and differentiation of Gram-negative bacteria, particularly those from the Enterobacteriaceae family. It is widely used in microbiology for analyzing various samples like clinical specimens, food, water, and dairy products. The medium contains ingredients that inhibit the growth of Gram-positive bacteria, while allowing Gram-negative bacteria to grow. Lactose fermenters produce pink colonies, while non-lactose fermenters form colorless or transparent colonies, aiding in differentiation. 

Nutrient media are basic culture media used for maintaining microorganisms, cultivating fastidious organisms by enriching with serum or blood and are also used for purity checking prior to biochemical or serological testing. Nutrient Agar is ideal for demonstration and teaching purposes where a more prolonged survival of cultures at ambient temperature is often required without risk of overgrowth that can occur with more nutritious substrate.

Chocolate agar base is a dehydrated culture medium formulated to support the growth of fastidious bacteria, particularly Haemophilus and Neisseria species. It is a nutrient-rich medium, essentially a variant of blood agar where the red blood cells are lysed (broken down) by heat, releasing essential growth factors like NAD (V factor) and hemin (X factor). This lysis is what gives the medium its characteristic chocolate-brown color

Peptone Water is recommended for studying the ability of an organism to ferment a specific carbohydrate, which aids in the differentiation of genera and species. It is utilized as a base for carbohydrate fermentation studies with the addition of sugar and indicators such as bromocresol purple, phenol red, or bromothymol blue. It is also suitable as a substrate in the study of indole production.

Haemolysins are exotoxins produced by bacteria that lyse red blood cells. The haemolytic reaction can be visualized on blood agar plates. On blood agar plates colonies of haemolytic bacteria may be surrounded by clear, colorless zone where the red blood cells have been lysed and the hemoglobin destroyed to a colorless compound.

Mueller Hinton Agar Base, a meticulously formulated dehydrated culture media designed for microbiological applications in laboratory settings.

Staphylococci are widespread in nature, although they are mainly found on the skin, skin glands and mucous membranes of mammals and birds. The coagulase-positive species i.e Staphylococcus aureus is well documented as a human opportunistic pathogen. The ability to clot plasma continues to be the most widely used and accepted criterion for the identification of pathogenic staphylococci associated with acute infections

TM MEDIA SS AGAR (SALMONELLA SHIGELLA AGAR) For differential and selective isolation of Salmonella and Shigella species from pathological samples and foods.

for preparation of various selective & identification media & isolation of organisms from clinical specimens

for cultivation of fastidious pathogenic bacteria, yeasts and molds

for selective isolation and enumeration of Salmonella Typhi and other Salmonella species

Field's Stain, often used in hematology, is a rapid staining technique for blood smears, particularly useful for screening malarial parasites. It's a version of the Romanowsky stain, similar to Giemsa or Leishman stains, and utilizes a combination of methylene blue and eosin to differentiate cellular components. Field's Stain A primarily contains methylene blue and Azure 1 in a phosphate buffer, while Field's Stain B contains eosin. 

Arkray Strong Carbol Fuchsin is a histological stain used in microbiology to identify acid-fast bacteria, particularly Mycobacterium species, through the Ziehl-Neelsen staining method.

Arkray Gram's Iodine Reagent is a crucial component in the Gram staining process, used to differentiate bacteria into Gram-positive and Gram-negative groups. It acts as a mordant, enhancing the adherence of the primary stain (crystal violet) to the bacterial cell wall.

Field's Stain B is a component of Field's stain, a rapid staining method for blood smears, particularly for detecting malaria parasites. It's a pinkish-red solution, also described as orange, and is used in conjunction with Field's Stain A

Arkray Lugol's Iodine Reagent is a solution of iodine and potassium iodide in water, commonly used as a staining solution to detect intestinal protozoa and helminth ova or larvae in fecal samples. It is also used as a reagent to detect the presence of starches, which turn a dark-blue/black color upon reaction with Lugol's solution. Additionally, it's used in cancer diagnosis, as it stains glycogen-rich cells brown, highlighting glycogen-depleted cancer cells. 

Arkray Methylene Blue Reagent is a solution of methylene blue, a thiazine dye, used for staining and other applications. It is commonly used as a biological stain, particularly in histology and microbiology, to highlight cellular structures and components. Additionally, methylene blue has various medicinal uses, including treatment for methemoglobinemia and as a potential neuroprotective agent. 

The Arkray Crystal VC (Dipstick) is a rapid, visual, immunochromatographic test used for the qualitative detection of Vibrio cholerae in stool samples. It specifically detects the lipopolysaccharide (LPS) antigen of both Vibrio cholerae O1 and O139 serotypes.
