PRODUCT DATA SHEET
Product Data Sheet: | Sheep Monoclonal Antibodies (SMAs) to: 25-hydroxy vitamin D (25-OH D) |
SMA Covered | 25-OH D2 specific: vitD2.2D10 25-OH D3 specific: vitD3.2F4 25-OH D2/D3 specific: vitD3.5H10 |
Production Description | The assay of vitamin D levels is of increasing interest and is commonly aimed at the 25-hydroxy variants. Such assays can be required to detect both 25-OH D2 and D3 and the availability of antibodies that can recognise both variants is of use in immunoassay design. |
