Specification

Product name Human Vitamin D3 (VD3) ELISA Kit
Reactivity Human
Applications ELISA
Applications notes This Human Vitamin D3 (VD3) ELISA Kit employs a two-site sandwich ELISA to quantitate VD3 in samples. An antibody specific for VD3 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyVD3 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for VD3 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 VD3 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Detection method Colorimetric
SampleType Cell culture supernatants, Other biological fluids, Plasma, Serum
Assay type Sandwich ELISA (quantitative)
Assay duration Multiple steps standard sandwich ELISA assay with a working time of 3-5 hours. It depends on the experience of the operation person.
Alternative VD3

Usage notes • 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.
Storage instructions The unopened kit should be stored at 2 - 8°C. After opening, please store refer to protocols.
Shipping Gel pack with blue ice.

Additional Information

Background Cholecalciferol is a form of vitamin D, also called vitamin D3. It is structurally similar to steroids such as testosterone, cholesterol, and cortisol (though vitamin D3 itself is a secosteroid). Cholecalciferol is produced industrially for use in vitamin supplements and to fortify foods by the ultraviolet irradiation of 7-dehydrocholesterol extracted from lanolin found in sheep's wool. Paraphrasing a more detailed explanation, cholesterol is extracted from wool grease and wool wax alcohols obtained from the cleaning of wool after shearing. The cholesterol undergoes a four step process to make 7-dehydrocholesterol, the same compound that is stored in the skin of animals. The 7-dehydrocholesterol is then irradiated with ultra violet light. Rodents are somewhat more susceptible to high doses than other species, and cholecalciferol has been used in poison bait for the control of these pests.
