Field Stain A and B Extra Pure
Original price was: $ 18.20.$ 18.09Current price is: $ 18.09.
Field Stain A and B Extra Pure are specially formulated biological stains used primarily in hematology and microbiology for rapid differential staining of blood smears and parasites, especially in field conditions. Field Stain A typically contains methylene blue and azure dyes dissolved in a phosphate buffer, which preferentially stains the nuclei and cytoplasm of white blood cells. Field Stain B, on the other hand, contains eosin and counterstains the red blood cells and other acidic cellular components. Together, these stains provide excellent contrast and clarity, making them ideal for identifying malarial parasites and conducting quick diagnostic assessments in low-resource or remote environments. Their extra pure quality ensures minimal contamination, consistent performance, and reliable results in both clinical and educational settings.
Field Stain A and B Extra Pure
Primary Uses
- Microscopic examination of blood smears:
Field Stain A (basic dye – methylene blue/azure) and Field Stain B (acidic dye – eosin) are primarily used together for rapid differential staining of blood films, particularly for identifying malaria parasites, trypanosomes, and other blood-borne pathogens. - Diagnostic hematology:
Vital for differentiating blood cells such as leukocytes, erythrocytes, and platelets under light microscopy in clinical labs and field settings.
Secondary Uses
- Parasitology field testing:
Favored in remote or low-resource settings due to its fast action and minimal need for lab infrastructure, supporting on-site diagnosis of parasitic infections. - Educational and training purposes:
Used in teaching laboratories for demonstrating blood cell morphology and staining techniques to students and trainees in hematology and pathology. - Comparative staining studies:
In research, it is sometimes used for comparing stain quality, efficiency, and morphological clarity with other stains like Giemsa or Wright’s.
