Vitamin D Binding Protein Biotinylated – Catalog number: B2010615 (0.1 mg)

Catalog number: B2010615
Lot number: Batch Dependent
Expiration Date: Batch dependent
Amount: 0.1 mg
Molecular Weight or Concentration: 1 mg/mL
Supplied as: Solution
Applications: versatile molecular tool in the study of the metabolism of vitamin D as well as the development of Vitamin D assays
Storage: -20C
Keywords: Group-Specific Component Biotin, Vitamin D Binding Protein Biotin, DBP-Biotin, VDBP-Biotin
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 D Binding Protein Biotinylated (Catalog number B2010615) is supplied as a solution in a defined 0.1 mg amount at a concentration of 1 mg/mL. In line with the supplier’s specification, it is intended for use as a versatile molecular tool in research on vitamin D metabolism and in the development of vitamin D assays, and is stored at −20C. The product is described as a highly purified preparation of vitamin D binding protein (VDBP) from human plasma conjugated to biotin.

The biotin tag enables rapid, high-affinity coupling to avidin/streptavidin systems, making the reagent immediately compatible with common capture, detection, and immobilization workflows. Teams building VDBP-related methods can use the defined concentration to titrate efficiently across platforms, assemble sandwich or competitive assay formats, and standardize signal pathways without performing in-house conjugations. The ready-to-use solution format reduces handling steps, while storage at −20C aligns with routine practices for maintaining reagent integrity during development and method qualification.

Typical research uses include constructing assay components where VDBP serves as a tracer or capture element, evaluating binding and wash conditions that influence vitamin D pathway measurements, and establishing control materials for optimization studies. The biotechnology-grade preparation—made with Type I ultrapure water and 0.22 µm filtration for solutions—supports low background and reproducibility expected in modern biochemical applications.

Why researchers choose this product:

  • Biotin-conjugated VDBP supplied as a solution for immediate method integration
  • Defined 0.1 mg amount at 1 mg/mL simplifies assay titration and documentation
  • Compatible with streptavidin/avidin systems for capture, detection, and immobilization
  • Stored at −20C to support stability across development and routine use
  • Biotechnology-grade preparation (Type I water, 0.22 µm filtration) for low background

This product is for Research Use Only (RUO). It is not intended for diagnostic or therapeutic use.
