Supplied as: Liquid Solution
Applications: tool in the research and development of vitamin B12 high and low working solutions (use with High Vitamin B12 Buffered Solution, catalog number B2010582)
Storage: 2-8°C
Keywords: depleted vitamin B12 solution, vitamin B12 diluent
Grade: Biotechnology grade. All products are highly pure. All solutions are made with Type I ultrapure water (resistivity >18 MΩ-cm) and are filtered through 0.22 um.

Vitamin B12 Buffered Diluent (Liquid Stable) is a biotechnology-grade reagent designed to support the preparation of vitamin B12 working solutions for assay calibration and reagent formulation. This folate-depleted matrix is optimized for use with the High Vitamin B12 Buffered Solution (Catalog # B2010582), enabling researchers to generate precise high and low concentration standards for immunoassay development, quality control, and analytical validation. Its liquid-stable format ensures ease of use and consistent performance across manual and automated workflows.

Researchers in clinical diagnostics, nutritional biochemistry, and metabolic health rely on buffered diluents to simulate physiological conditions and optimize assay sensitivity. This solution provides a clean background for accurate quantification of vitamin B12 in serum, plasma, and fortified food samples. Filtered through 0.22 µm membranes and prepared with ultrapure water, it minimizes background interference and ensures high reproducibility. Supplied in a 50 mL format and stored at 2–8°C, it integrates seamlessly into ELISA, CLIA, and other vitamin B12 detection platforms.

Key benefits:

  • Liquid-stable diluent for vitamin B12 assay calibration and reagent development

  • Designed for use with High Vitamin B12 Buffered Solution (Catalog # B2010582)

  • Provides a vitamin B12-depleted matrix for accurate quantification

  • Filtered through 0.22 µm membranes using ultrapure water

  • Supplied in 50 mL format and stored at 2–8°C for long-term stability

Products are for in vitro research use only (RUO).
