Vitamin D Binding Protein (Highly Pure) – Catalog Number: B2010417 (1 mg)

Catalog number: B2010417
Lot number: Batch Dependent
Expiration Date: Batch dependent
Amount: 1 mg
Molecular Weight or Concentration: 52 kDa
Supplied as: Lyophilized Powder
Appearance: White
Applications: high purity Vitamin D Binding Protein from human Plasma (VDBP). VDBP is the major carrier of vitamin D and its metabolites in blood.
Storage: -20C
Keywords: Group-Specific Component, Vitamin D Binding Protein, DBP, VDBP
Grade: Biotechnology grade. All solid components are highly pure (minimum 95%). All solutions are made with Type I ultrapure water (resistivity >18 MΩ-cm) and are filtered through 0.22 um.

Vitamin D Binding Protein (Highly Pure) is supplied as a lyophilized powder in a defined 1 mg quantity with a listed molecular weight of 52 kDa. The product is described by the supplier as a high-purity preparation of human plasma VDBP—recognized as the major carrier of vitamin D and its metabolites in blood—and is stored at −20 C. The white, lyophilized format is practical for controlled reconstitution and aliquoting, supporting consistent handling across method development and routine research use.

Within vitamin D pathway studies, purified VDBP is valuable as a standard or component when researchers need the carrier protein itself—for example, in adsorption/release experiments, binding studies, or when characterizing conditions that influence vitamin D transport. The powder format allows labs to select reconstitution buffers compatible with downstream workflows and to prepare working stocks at precisely defined concentrations. Because the material is provided as biotechnology grade—with production details noting ultrapure water and 0.22 µm filtration for solutions—the reagent aligns with common expectations for low background and reliable performance in biochemical applications.

Use cases typically include building model systems that probe interactions between vitamin D metabolites and their plasma carrier, benchmarking extraction or release steps that depend on VDBP, or assembling assay components where VDBP acts as a capture, competitor, or control protein. Clear specifications (amount, molecular weight, storage, supplied-as) simplify documentation and SOP integration for teams standardizing vitamin D–related experiments in research settings.

Why researchers choose this product:

  • Lyophilized powder (white) for flexible reconstitution and storage
  • Defined 1 mg amount and listed 52 kDa molecular weight
  • Biotechnology-grade preparation; solutions filtered through 0.22 µm
  • Stored at −20 C for stability and reproducibility
  • Appropriate for studies involving VDBP’s role in vitamin D transport and assay development

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