Gram staining is a method of differentiating bacterial species and it is commonly known and used in microbiology. It is also one of the most frequently used diagnostic methods in hospital and clinical laboratories. Gram staining differentiates bacteria into two groups: Gram-positive and Gram-negative. That division is based on the two groups’ bacterial membrane structural differences, i. e. their capability of retaining the dye. Gram-positive bacteria have a thicker cellular membrane which enables retaining the dye inside the cell by treating them with iodine solution that creates insoluble iodine and primary dye complex. Gram-negative bacteria have a thinner cellular membrane structure that cannot retain the dye. It washes away through the membrane and using counterstaining forms the basis for differentiating between the two bacteria groups. BioGnost’s BioGram 4 kit contains Gram Crystal Violet 1% solution, stabilized Gram Lugol solution, two packages of Gram Decolorizer solution 2 and Gram Safranin solution. Its characteristics make it an optimal bacteria staining agent which provides consistent results.
BioGram 4 kit
Four-reagent kit for identification of bacteria according to Gram. Kit contains Gram Crystal Violet 1% solution, stabilized Gram Lugol solution, double amount of Gram Decolorizer solution 2 and Gram Safranin solution as counterstain.
5×100 ml bottles
TB-Stain Histo kit
Three-reagent kit for staining acid-fast bacteria (pathogenic mycobacteria) in histology sections, sputum, smears and culture smears according to Ziehl-Neelsen. Heating of the carbol-fuchsin solution is avoided in this protocol hence omitting the release of hazardous phenolic vapours.
Giemsa HP kit
Four-reagent kit for staining Helicobacter pylori in gastroscopic sections according to Lennart. Advantages of this method for detecting H. pylori are sensitive and reproducible results and easy performance.
Martius Scarlet Blue (MSB) kit
Seven-reagent kit used for fibrin visualisation, especially of older clusters. This method is a modification of Masson Trichrome and is ideal for studying connective tissue and vascular pathology.
Alcian Yellow Toluidine Blue kit
Six-reagent kit for staining Helicobacter pylori in gastric tissue sections. This method is one of the most popular non-silver methods for staining of H. pylori, where bacteria are stained blue in contrast to yellow mucins.
Field kit 500ml
Ready to use two-reagent kit for rapid and efficient staining and detection of parasites in haematology samples. Primarily used for staining thin and thick blood smears (dense drop) for purpose of diagnosing blood parasites. Reagents are stored in containers that can be used as staining jars.
Papanicolaou Rapid Staining Kit, for 100 Tests
Ready-to-use eight-reagent kit (in 18 containers that can be used as staining jars) for rapid progressive gynecology and non-gynecology cytological samples. Contains xylene substitute as clearing agent and xylene substitute-based medium for permanent covering of samples.
