Staining Analysis Service
The diagnosis of aquatic animal diseases often hinges on microscopic evidence, making staining analysis the critical diagnostic checkpoint for securing aquaculture yields worldwide. BioVenic stands at the forefront of this field, offering comprehensive services that span routine histopathology to molecular precision techniques, underpinned by optional services in disease modeling using advanced genetic engineering platforms. This microscopic approach provides definitive, visual confirmation linking pathogens, toxic agents, or environmental stressors to the specific host tissue response, enabling targeted intervention strategies and regulatory compliance for global clients.
Staining analysis is the gold standard for contextual disease diagnosis in fish, shellfish, and other aquatic species, moving investigation beyond mere molecular detection to confirm the biological impact of a disease agent. By processing tissues through meticulous fixation and staining protocols, pathologists can visually assess the entire cellular and organ architecture to identify lesions, quantify inflammation, and localize foreign bodies or pathogens. This indispensable diagnostic tool is crucial for differentiating between non-infectious pathologies - such as nutritional lesions or toxicosis - and specific microbial, parasitic, or viral infections. Because disease footprints often manifest uniquely at the tissue level (e.g., cellular inclusion bodies suggesting viral activity), high-quality staining analysis is the first and most critical step in formulating a decisive health management plan.

BioVenic offers a tiered, comprehensive range of staining services, ensuring that the diagnostic depth meets the complexity of the client's investigation. Our platform integrates gold-standard tissue handling with cutting-edge digital analysis tools, allowing us to generate both the foundational data and the advanced molecular context required for definitive pathology reports.
| Service Category | Specific Stains/Techniques | Key Applications |
| Routine Histopathology | H&E (Hematoxylin and Eosin) | Essential for visualizing general tissue and cell morphology, quantifying inflammation severity, and identifying basic lesions like necrosis and inclusion bodies. |
| Connective Tissue & Matrix | Masson's Trichrome Van Gieson Picrosirius Red |
Quantifies the degree of fibrosis (collagen deposition) in vital organs (liver, kidney) and assesses the maturity of wound healing or chronic damage. |
| Special Pathogen Identification | Gram Stain Grocott's Methenamine Silver (GMS) PAS |
Differential identification of bacteria (Gram-positive/negative), fungi, oomycetes, and visualization of basement membranes and mucoid substances. |
| Molecular Precision | Immunohistochemistry (IHC) Immunofluorescence (IF) In Situ Hybridization (ISH) |
Confirms the presence and precise location of specific viral or bacterial antigens and localizes immune cells or genetic material within lesions. |
| Metals & Minerals | Perl's Prussian Blue Von Kossa |
Detects and quantifies deposits of iron (hemosiderin) in tissues and identifies pathological calcification within soft tissues. |
The BioVenic research workflow begins with a pre-submission consultation to optimize sample integrity and sectioning. Routine H&E establishes the foundational morphological data, guiding the selection of advanced Special Stains or IHC assays to achieve molecular-level insight. We also provide related products for zebrafish staining, such as antibody and kits. Click here to explore our selection of over 200 zebrafish products.
