5,6-trans-Vitamin D3(5,6-trans-Cholecalciferol) is an isoform of Vitamin D3, which is converted from Vitamin D3 on the skin surface after light exposure.

Ergocalciferol (Vitamin D2 (Calciferol)) is a derivative of ergosterol formed by ultraviolet rays breaking of the C9-C10 bond with a strong inhibitory effect against bladder tumor promotion by sodium saccharin, and it induces cell differentiation in leukemia cells. Vitamin D2 is an inhibitor of DNA Polymerase.

VD3-D6 is the deuterated form of Vitamin D3; tools for determination of Vitamin D3 metabolites in human serum.

24, 25-Dihydroxy VD3 is closely related to 1,25-dihydroxy vitamin D3, the active form of vitamin D3.

Calcitetrol is the hormonally active form of vitamin D with three hydroxyl groups.

1α,25-Dihydroxyprevitamin D3, the most potent biologically active form of vitamin D3 (VD3), is used to regulate calcium absorption [1].

25-OH Vitamin D3-KLH is a hapten-carrier protein conjugate formed by coupling 25-OH Vitamin D3 to keyhole limpet hemocyanin (KLH). As a hapten, 25-OH Vitamin D3 alone cannot induce an immune response and must be conjugated to a large molecular protein to become a complete antigen with immunogenicity.

25-OH Vitamin D3-BSA is a hapten-carrier protein conjugate formed by coupling 25-OH Vitamin D3 to bovine serum albumin (BSA). As a hapten, 25-OH Vitamin D3 alone cannot induce an immune response and must be conjugated to a large molecular protein to become a complete antigen with immunogenicity. 25-OH Vitamin D3-BSA may be supplied as a lyophilized powder or as a solution. The solution is prepared in 0.01 M PBS (pH 7.4) buffer at a typical concentration of 1 mg/mL.
