Auxiliary Test Reagents

Buffers

Buffers are fundamental to nearly all diagnostic research applications, as they maintain a stable pH environment that is critical for preserving the activity of enzymes, antibodies, nucleic acids, and other biomolecules involved in diagnostic reactions. Our buffers are formulated in a variety of compositions—including phosphate-buffered saline (PBS), Tris, MES, and PIPES—to suit diverse experimental requirements, from nucleic acid amplification and protein analysis to cell-based assays and immunoassays. We offer both ready-to-use and powder formats, with optimized concentrations to eliminate the need for time-consuming dilution and calibration. Our buffers are designed to resist pH fluctuations caused by temperature changes, reaction byproducts, or sample composition, ensuring that diagnostic reactions proceed as intended and delivering consistent, reliable results across experiments.

Cleaning Solutions

Contamination is a major threat to diagnostic research, as even trace amounts of impurities can skew results and invalidate experiments. Our cleaning solutions are specially formulated to effectively remove contaminants such as proteins, nucleic acids, lipids, and reagent residues from lab equipment, including pipettes, reaction vessels, slides, and analytical instruments. Unlike generic cleaning agents that may leave harmful residues or damage sensitive equipment, our solutions are mild yet powerful, designed to be compatible with a wide range of materials used in diagnostic research, including plastic, glass, and metal. We offer specialized formulations for different cleaning needs—from routine equipment maintenance to deep cleaning of critical components—ensuring that lab tools remain free of contaminants and ready for use in high-sensitivity diagnostic experiments.

Diluent

Dilution is a common step in diagnostic research, used to adjust sample concentrations, reduce interference from matrix components, and prepare standards for calibration curves. Our diluents are tailored to maintain the stability and integrity of analytes during dilution, preventing degradation or denaturation that could affect experimental results. We offer a range of diluent formulations, including serum-based, buffer-based, and protein-stabilized options, to accommodate different sample types, such as blood, urine, saliva, and tissue homogenates. Our diluents are optimized to minimize background noise in diagnostic assays, ensuring that diluted samples retain their biological activity and that results accurately reflect the original sample composition. Whether for immunoassays, nucleic acid detection, or cell counting, our diluents provide a reliable solution for precise sample dilution.

Substance Dissolving Solutions

Many diagnostic research applications require the dissolution of solid samples, such as drugs, biomarkers, or chemical reagents, into a liquid form for analysis. Our substance dissolving solutions are engineered to efficiently dissolve a wide range of compounds, including hydrophobic molecules, proteins, peptides, and small molecules, while preserving their structural and functional integrity. These solutions are formulated with high-purity solvents and solubilizing agents that minimize interference with downstream diagnostic reactions, such as HPLC, mass spectrometry, or immunoassays. We offer customized dissolving solutions for hard-to-dissolve compounds, addressing common challenges such as low solubility, aggregation, or degradation, and ensuring that researchers can efficiently prepare samples for analysis without compromising result quality.

Sample Preparation Solutions

Effective sample preparation is the foundation of accurate diagnostic research, as it involves isolating and purifying target analytes—such as nucleic acids, proteins, or cells—from complex biological matrices. Our sample preparation solutions are designed to streamline this critical step, offering efficient, reliable methods for sample lysis, extraction, purification, and concentration. From magnetic bead-based extraction kits for nucleic acids to protein precipitation solutions and cell lysis buffers, our products are optimized to maximize analyte recovery while minimizing contamination and matrix interference. These solutions are compatible with a wide range of sample types, including liquid biopsies, tissue samples, and cell cultures, and are designed to integrate seamlessly with downstream diagnostic assays, such as PCR, qPCR, ELISA, and next-generation sequencing.

Staining Agents

Visualization of cells, tissues, or biomolecules is essential for many diagnostic research applications, including histopathology, cytology, and cell biology studies. Our staining agents are formulated to provide clear, consistent staining of target structures, enabling researchers to accurately observe and analyze cellular morphology, protein localization, and nucleic acid distribution. We offer a comprehensive range of staining agents, including hematoxylin and eosin (H&E) stains for general tissue staining, fluorescent dyes for immunofluorescence assays, and special stains for specific cellular components—such as mitochondria, nuclei, or cytoskeletons. Our staining agents are designed to be easy to use, with consistent staining intensity and minimal background, ensuring that researchers can reliably visualize and quantify target structures in their samples.

Cell Culture Reagents

Cell-based diagnostic research relies on the ability to maintain healthy, viable cell cultures that accurately mimic in vivo conditions. Our cell culture reagents are formulated to support the growth, proliferation, and differentiation of a wide range of cell types, including primary cells, immortalized cell lines, and stem cells, which are critical for developing and testing diagnostic assays. Our portfolio includes cell culture media, sera, growth factors, antibiotics, and supplements, all optimized to provide the essential nutrients, vitamins, and growth factors that cells need to thrive. We offer both serum-containing and serum-free formulations, as well as specialized media for specific cell types—such as cancer cells, immune cells, or epithelial cells—ensuring that researchers can maintain consistent, high-quality cell cultures for their diagnostic research.

Cell Transfection Reagents

Genetic manipulation is a key tool in diagnostic research, enabling researchers to study gene function, develop recombinant proteins for diagnostic assays, and engineer cells for disease modeling. Our cell transfection reagents are designed to efficiently deliver nucleic acids—such as DNA, RNA, or siRNA—into target cells with minimal cytotoxicity, ensuring high transfection efficiency and preserving cell viability. We offer a range of transfection reagents, including lipid-based, polymer-based, and viral-based options, to accommodate different cell types and experimental needs. Our transfection reagents are optimized for ease of use, with simple protocols that eliminate the need for specialized equipment, and are compatible with both adherent and suspension cell cultures. Whether for transient or stable transfection, our reagents provide a reliable solution for genetic manipulation in diagnostic research.
