Provided herein are antigenic molecules that can be used to generate antibodies capable of binding to a vitamin D derivative, such as 25-hydroxyvitamin D2 and/or 25-hydroxyvitamin D3, or a 25-hydroxyvitamin D analog, such as a vitamin D-C22 immunogenic molecule or compound. Antibodies produced using these antigenic molecules, and related antigenic compounds, are also described. In addition, disclosed herein are methods for detecting vitamin D deficiency in a subject, methods for treating a subject suspected of having a vitamin D deficiency, methods for monitoring progression of vitamin D deficiency in a subject, and methods for monitoring treatment of vitamin D deficiency in a subject in need thereof. The methods involve the detection or quantification of 25-hydroxyvitamin D2 and D3. Also provided are methods and reagents for the detection or quantification of 25-hydroxyvitamin D2 and D3, methods for stabilizing vitamin D analogs, and methods for separating 25-hydroxyvitamin D2 and D3 from vitamin D binding protein in a biological sample.

Antibodies to 25-hydroxyvitamin D2 and D3 for detecting total 25-hydroxyvitamin D

Antibodies to 25-hydroxyvitamin D2 and D3

Method for detecting total 25-hydroxyvitamin D using antibodies to 25-hydroxyvitamin D2 and D3

The present invention discloses compositions that comprise compounds relating to vitamin D. These compounds are useful for assays in the determination and distinguishing of certain 3-epimeric 25 hydroxyvitamin D and non-epimeric 25 hydroxyvitamin D. The compositions of the present invention may be used for example as immunogens used to develop antibodies to certain vitamin D compounds or conjugates used in assays for certain vitamin D compounds or used as a solid phase reagent in assays. The composition comprises a compound of one or more of the generic formula (R)-(L)-Z.

Compositions relating to vitamin D

This invention relates to compositions, methods and kits for determining the presence and/or amount of vitamin D analytes, including vitamin D isomers, and metabolites thereof in a sample suspected of containing the same. Compounds include compounds of the Formula I, namely, (R)-(L)-Z wherein R, L, p and q are as defined herein. These compounds are capable of binding specifically to corresponding antibodies. Compounds and antibodies in accordance with the principles described herein can have therapeutic activity. These compounds may be administered in therapeutically effective amount, which is an amount to provide treatment of a particular disease state associated with vitamin D. Administration of the examples of compounds in accordance with the principles described herein can be by means of any of the accepted modes of administration for agents that serve similar utilities.

Provided herein are antigenic molecules that can be used to generate antibodies capable of binding to a vitamin D derivative, such as 25-hydroxyvitamin D2 and/or 25-hydroxyvitamin D3, or a 25-hydroxyvitamin D analog, such as a vitamin D-C22 immunogenic molecule or compound. Antibodies produced using these antigenic molecules, and related antigenic compounds, are also described. In addition, disclosed herein are methods for detecting vitamin D deficiency in a subject, methods for treating a subject suspected of having a vitamin D deficiency, methods for monitoring progression of vitamin D deficiency in a subject, and methods for monitoring treatment of vitamin D deficiency in a subject in need thereof. Also provided are methods and reagents for the detection or quantification of 25-hydroxyvitamin D2 and D3, methods for stabilizing vitamin D analogs, and methods for separating 25-hydroxyvitamin D2 and D3 from vitamin D binding protein in a biological sample.
