Diff-Quick Staining Kit | Clinical & Vet Diagnostics
Rapid, High-Contrast Cellular Differentiation
The Diff-Quick Staining Kit is an indispensable diagnostic tool for fast-paced clinical and research laboratories. Traditional Romanowsky staining protocols can be time-consuming and complex. Our optimized Diff-Quick formulation streamlines this process into a simple, 15-to-30-second dip procedure, allowing pathologists and technicians to make rapid, on-site evaluations of cellular morphology.
The system utilizes a tri-component methodology: a methanol-based fixative to stabilize the specimen, an eosinophilic dye (Solution I) that stains cytoplasm and basic proteins varying shades of pink and red, and a basophilic thiazine dye (Solution II) that stains nuclei and acidic components deep blue to purple. The result is exceptionally crisp cellular resolution.
Diff-Quick Staining Kit Diagnostic Quality & Laboratory Standardization
In clinical diagnostics and advanced biological research, reagent consistency is non-negotiable. By integrating our diagnostic-grade stain into your laboratory protocols, you ensure that every slide yields uniform, highly reproducible color balances. This consistency is essential for accurate cell counting, morphological assessments, and seamless alignment with clinical accreditation standards.
Diff-Quick Staining Kit Applications & Uses
Our Diff-Quick Staining Kit provides exceptionally rapid chemical performance for diverse biological evaluations:
-
Hematology: The premier choice for evaluating peripheral blood smears, allowing for rapid differentiation of neutrophils, eosinophils, basophils, lymphocytes, and monocytes.
-
Cytopathology: Highly effective for the rapid on-site evaluation (ROSE) of Fine Needle Aspiration (FNA) biopsies, body fluids, and tissue imprints to rapidly assess cellular adequacy.
-
Microbiology: Excellent for identifying certain microorganisms, including Helicobacter pylori, directly from gastric biopsies or cytological smears.
-
Veterinary & Reproductive Science: Widely utilized in veterinary pathology and for performing detailed morphological evaluations of sperm cells.
Diff-Quick Staining Kit Flexible Packaging to Suit Institutional Demands
To ensure maximum chemical stability and ease of use, our Diff-Quick Staining Kit is supplied as a complete, ready-to-use 3-part system. Each “Kit” contains three matching bottles (Fixative, Solution I, Solution II) packaged in chemically resistant, tightly sealed containers:
-
250 ml Kit (3 x 250ml): Ideal for smaller clinics, veterinary practices, or specialized academic research labs.

Safety & Handling Warning:
The Diff-Quick Fixative solution contains Methanol, which is highly flammable and toxic if ingested, inhaled, or absorbed through the skin. Solution I and Solution II contain biological dyes that will heavily stain skin, clothing, and laboratory surfaces. Always use appropriate Personal Protective Equipment (PPE), including nitrile or latex gloves, safety goggles, and a lab coat. Ensure the staining area is well-ventilated or located under a fume hood. Keep the fixative tightly capped when not in active use to prevent evaporation and fire hazards. Please consult the comprehensive Safety Data Sheets (SDS) provided by Gündüz Kimya prior to use.
