Mouse Vitamin D2 (VD2) ELISA Kit

Ergocalciferol is a provitamin form of vitamin D, also called vitamin D2. Ergocalciferol is created when ultraviolet light activates ergosterol. Ergocalciferol is produced in fungi synthetically through irradiation of ergosterol. Human bioavailability of vitamin D2 from vitamin D2-enhanced button mushrooms via UV-B irradiation is effective in improving vitamin D status and not different from a vitamin D2 supplement. Vitamin D2 from UV-irradiated yeast baked into bread is bioavailable. By visual assessment or using a chromometer, no significant discoloration of irradiated mushrooms, as measured by the degree of "whiteness", was observed. One study found low vitamin D2 levels in patients with Alzheimer's disease, but this observational study did not prove cause or effect related to ergocalciferol and vitamin D2 deficiency in the diet.

Mouse Vitamin D2 (VD2) ELISA Kit has high sensitivity and excellent specificity for detection of Mouse VD2. No significant cross-reactivity or interference between Mouse VD2 and analogues was observed.

This Mouse Vitamin D2 (VD2) ELISA Kit employs a two-site sandwich ELISA to quantitate VD2 in samples. An antibody specific for VD2 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyVD2 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for VD2 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of VD2 bound in the initial step. The color development is stopped and the intensity of the color is measured.

• Do not mix components from different kit lots or use reagents beyond the kit expiration date.• Allow all reagents to warm to room temperature for at least 30 minutes before opening.• Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination.• Unused wells must be kept desiccated at 4 °C in the sealed bag provided.• Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.• It is recommended that all samples and standards be assayed in duplicate or triplicate.
