Applications & Workflow Integration

Efficient, standardized tissue diagnostics are foundational for modern clinical and research laboratories. With Merck’s Tissue Diagnostics range, you can optimize every workflow step, ensuring reliable performance across sample types and diagnostic applications. These reagents are essential for surgical pathology, cancer diagnostics, routine histology, and biomarker discovery.

By integrating Merck fixatives, decalcifiers, stains, and mounting media, your team streamlines tissue processing, reduces variability, and accelerates turnaround—from tissue collection to slide review. Whether preparing H&E-stained sections or performing advanced IHC, Merck’s universal reagents help you deliver precise, reproducible results every time.

Reagent Categories: Fixatives, Decalcifiers & Embedding Media

A robust histology workflow begins with proper tissue preservation. Merck’s range includes the gold standard 10% Neutral Buffered Formalin (NBF), which preserves cellular and structural integrity while supporting downstream antigen retrieval for IHC. For calcified samples, OSTEOMOLL® Decalcifying Solution enables gentle, effective decalcification of bone and dental tissues, protecting both morphology and antigenicity.

Additionally, embedding media like Histosec® Paraplast® allow for optimal infiltration and sectioning, making even delicate or challenging tissue types accessible for subsequent staining and analysis. Each product is formulated for compatibility with a wide variety of sample types and is delivered ready-to-use, minimizing preparation errors and maximizing productivity.

Key SKUs:

• 10% Neutral Buffered Formalin (Cat. No. 100496)
• OSTEOMOLL® Decalcifying Solution (Cat. No. 101468)
• Histosec® Embedding Medium (Cat. No. 64704)

Staining Solutions: H&E, Special Stains & IHC Reagents

Tissue staining is at the heart of diagnostic pathology. Merck offers a broad portfolio of routine and specialty stains—such as the flagship Haematoxylin and Eosin (H&E) kits, Masson’s Trichrome, PAS, and Congo Red—to highlight cellular structures and extracellular components with clarity and contrast.

For labs engaged in advanced immunohistochemistry, Merck supplies IHC reagent kits and antibodies optimized for reliable biomarker detection. These solutions are IVD-registered and undergo strict batch-to-batch quality control to guarantee sensitivity, specificity, and regulatory compliance.

Key SKUs:

• Haematoxylin Solution (Cat. No. 105175)
• Eosin Y Solution (Cat. No. 115935)
• PAS Staining Kit (Cat. No. 101646)
• IHC Reagent Kit (Cat. No. 533223)

Mounting Media & Tissue Clearing Solvents

Proper mounting and tissue clearing are critical for optimal slide preservation and microscopic evaluation. Merck’s mounting media range includes both aqueous and non-aqueous solutions, such as Histokitt® (Cat. No. 107672) and Fluoromount™ (Cat. No. F4680), supporting routine brightfield and fluorescence applications.

Tissue clearing agents like xylene substitutes ensure transparency and minimize background, making even densely stained slides easy to interpret. These reagents are formulated for rapid processing and compatibility with all major staining protocols, reducing workflow bottlenecks and supporting high-throughput environments.

Quality Control Slides & Diagnostic Accessories

Consistency in tissue diagnostics is achieved through standardized controls and accessories. Merck’s ISOSLIDE® quality control slides feature embedded positive and negative controls for common histological and IHC stains, enabling continuous verification of staining quality and protocol accuracy.

Diagnostic accessories—including disposable microtome blades, slide storage solutions, and labeling systems—further streamline your lab’s operations, supporting regulatory compliance and audit readiness.

Key SKUs:

• ISOSLIDE® H&E Control Slide (Cat. No. 100330)
• ISOSLIDE® IHC Control Slide (Cat. No. 100340)

Regulatory Compliance & IVD Certification

Merck Tissue Diagnostics reagents are CE-certified and manufactured under ISO 13485 and cGMP quality systems, ensuring reliability and traceability for both clinical and research applications. Every batch undergoes rigorous validation to meet IVD and medical device regulations, enabling seamless accreditation for your laboratory.

By choosing Merck, you benefit from proven global compliance standards—trusted by hospitals, pathology labs, and biopharma partners worldwide.
