Vitamin B12 Biotin Conjugate

Catalog number: B2010608
Lot number: Batch Dependent
Expiration date: Batch Dependent
Amount: 1 mg
Concentration: 5.0 mg/mL
Supplied as: Solution
Applications: Versatile molecule used in the study of vitamin B12 metabolism and development of vitamin B12 assays.
Storage: −20°C
Keywords: Biotin PEG Vitamin B12, Cobalamin PEG Biotin, Cyanocobalamin PEG Biotin
Grade: Biotechnology grade. All products are highly pure. Solutions made with Type I ultrapure water (resistivity >18 MΩ·cm), filtered through 0.22 µm.

Vitamin B12 Biotin Conjugate is a biotechnology-grade reagent designed for advanced assay development and metabolic research. Supplied as a 1 mg solution at 5.0 mg/mL concentration, this conjugate combines cyanocobalamin (vitamin B12) with biotin via a PEG linker, enabling high-affinity binding to streptavidin-coated surfaces. It is ideal for use in ELISA, CLIA, and biosensor platforms focused on vitamin B12 quantification, transport studies, and receptor-ligand interactions.

Researchers in nutritional biochemistry, clinical diagnostics, and molecular biology rely on biotinylated conjugates to enhance assay sensitivity and streamline detection workflows. This reagent supports robust signal generation and consistent performance across manual and automated systems. Filtered through 0.22 µm membranes and prepared with ultrapure water, it ensures high purity and minimal background interference. Stored at –20°C, it maintains long-term stability for repeated use in high-throughput and precision applications.

Key benefits:

  • Biotinylated vitamin B12 for streptavidin-based assay platforms

  • Supplied as a 1 mg solution at 5.0 mg/mL concentration

  • Supports ELISA, CLIA, and metabolic pathway research

  • Filtered through 0.22 µm membranes using ultrapure water

  • Stored at –20°C for long-term reagent integrity

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