The basic dye component is used to stain structures with basophilic characteristics during appropriately performed blood-smear staining. BIOLAB specifies approximately: - Buffer - **Methylene Blue – 0.5%** - Preservative * * * ## Field Stain B – Composition & Function **Field Stain B** uses an eosin-based staining system complementary to Field Stain A. BIOLAB specifies approximately: - Buffer - **Water-soluble Eosin – 0.4%** - Preservative The acidic dye component helps differentiate acidophilic cellular structures when used as part of the complete Field staining procedure. * * * ## How Does Field Stain A & B Work? The Field staining system uses complementary basic and acidic dyes. Polychromated methylene blue and eosin selectively stain different cellular components according to their chemical characteristics, helping create colour differentiation between structures within a prepared peripheral blood smear. This staining contrast assists trained laboratory personnel during microscopic examination of blood cells and, where the laboratory procedure is validated for that purpose, demonstration of blood-associated parasites. **Staining quality depends on much more than the reagent alone.** Smear thickness, fixation, timing, reagent condition, washing, water quality, microscopy and operator technique can all affect the final appearance. * * * ## What Is Field Stain Used For? BIOLAB Field Stain A & B is intended for professional blood-smear staining workflows. Typical laboratory applications may include: - Peripheral blood smear staining - Microscopic examination of blood-cell morphology - Hematology teaching and laboratory demonstration - Professional microscopy workflows - Demonstration of hemoparasites where the method is validated The staining reagent itself does not establish a clinical diagnosis. Microscopic findings must be interpreted by appropriately trained laboratory or healthcare professionals. * * * ## Specimen & Blood Collection Considerations BIOLAB documentation describes use with peripheral blood samples prepared on clean glass slides. Where anticoagulated blood is used, the manufacturer documentation refers to **K3 EDTA** as an appropriate anticoagulant and advises avoiding heparin for this staining workflow. Blood smears should be prepared according to the laboratory's validated procedure and current BIOLAB instructions. For hematology specimen collection, browse the [**Microsidd Blood Collection Tubes Collection**](https://microsidd.com/collections/blood-collection-tubes). Microsidd also supplies [**K3 EDTA Blood Collection Tubes**](https://microsidd.com/products/k3-edta-blood-collection-tubes-2ml) for professional hematology specimen collection. * * * ## Microscope Slides for Peripheral Blood Smears Correct slide preparation is an essential part of blood-smear microscopy. Microsidd supplies [**Microscope Glass Slides**](https://microsidd.com/products/microscope-glass-slides) for professional laboratory specimen preparation. You can also browse the [**Microscope Slides & Laboratory Glassware Collection**](https://microsidd.com/collections/microscope-glass-slides-glass) for slides, cover slips and related microscopy products. * * * ## Is BIOLAB Field Stain Ready to Use? Yes. BIOLAB describes the Field Stain reagents as **ready to use**. This means routine dilution or preparation should not be assumed unless specifically directed by the current product label or package insert. Do not alter reagent concentration or combine reagents using an unvalidated procedure. * * * ## Storage & Stability BIOLAB documentation states that the reagents are stable at **room temperature until the expiry date stated on the individual label** when stored according to manufacturer instructions. For dependable laboratory performance: - Keep bottles securely closed when not in use - Avoid contamination of reagent bottles - Do not interchange bottle caps - Protect reagents from unsuitable storage conditions - Do not use after the labelled expiry date - Follow the temperature and storage requirements printed on the current product label If the package supplied contains storage instructions that differ from general information shown here, always follow the current manufacturer label and package insert. * * * ## Field Stain A & B Pack Contents | Component | Quantity | Pack Size | | --- | --- | --- | | **BIOLAB Field Stain A** | 1 Bottle | 500 mL | | **BIOLAB Field Stain B** | 1 Bottle | 500 mL | | **Total** | 2 Bottles | 2 × 500 mL | **Important:** This Microsidd listing is for **Field Stain A 500 mL + Field Stain B 500 mL**.
