Vitamin D BSA Conjugate Biotinylated – Catalog number: B2010610 (0.1 mg)

Vitamin D BSA Conjugate Biotinylated is provided as a biotechnology-grade solution in a defined 0.1 mg amount (Catalog number B2010610) with a listed molecular weight of 66 kDa. The conjugate contains bovine serum albumin (BSA) linked to 25-OH Vitamin D₃ via a carbon spacer arm and additionally labeled with biotin; each BSA molecule carries several 25-OH Vitamin D₃ units and several biotin units. In keeping with the supplier’s instructions, the material is stored at −20 °C and can be diluted with phosphate-buffered saline (PBS) for use in workflows.

Designed as a versatile molecular tool for research on vitamin D metabolism and for the development of vitamin D assays, this conjugate supports common streptavidin/avidin capture or detection schemes while presenting multiple 25-OH Vitamin D₃ epitopes on a single carrier. The combination of a defined protein backbone, spacer-mediated presentation of the vitamin D moiety, and biotin labeling enables straightforward assembly of competitive or sandwich-style assay components, immobilization on streptavidin-coated surfaces, or inclusion as a tracer/capture element in method development. The solution format avoids reconstitution steps and simplifies titration during optimization.

Researchers constructing vitamin D detection methods can incorporate this reagent to evaluate binding conditions, calibrate capture/trace pairings, and streamline prototype CLIA-style readouts. The biotech-grade preparation (Type I ultrapure water; 0.22 µm filtration for solutions) aligns with expectations for low background and lot-to-lot reliability. Clear specifications—amount, molecular weight, storage, and supplied-as—facilitate SOP documentation and cross-lab standardization.

Why researchers choose this product:

• Biotin-labeled BSA carrying multiple 25-OH Vitamin D₃ units; spacer-linked presentation
• Defined 0.1 mg amount and listed 66 kDa molecular weight for predictable setup
• Ready-to-use solution; can be diluted in PBS for assay development
• Stored at −20 °C to support stability and reproducibility
• Appropriate as a versatile molecular tool for vitamin D metabolism research and assay construction
