7-Dehydrocholesterol (7-DHC) ELISA Kit

7-Dehydrocholesterol (7-DHC) ELISA Kit is available at Gentaur for next week delivery.

Specificity: This assay has high sensitivity and excellent specificity for detection of 7-Dehydrocholesterol (7-DHC).

Cross Activity: This assay has high sensitivity and excellent specificity for detection of 7-Dehydrocholesterol (7-DHC).

Test principle: This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to 7-Dehydrocholesterol (7-DHC) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled 7-Dehydrocholesterol (7-DHC) and unlabeled 7-Dehydrocholesterol (7-DHC) (Standards or samples) with the pre-coated antibody specific to 7-Dehydrocholesterol (7-DHC). After incubation the unbound conjugate is washed off. Next, avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of 7-Dehydrocholesterol (7-DHC) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of 7-Dehydrocholesterol (7-DHC) in the sample.

Assay procedure summary: 1. Prepare all reagents, samples and standards; 2. Add 50 µL standard or sample to each well.     And then add 50 µL prepared Detection Reagent A immediately.     Shake and mix. Incubate 1 hour at 37°C; 3. Aspirate and wash 3 times; 4. Add 100 µL prepared Detection Reagent B. Incubate 30 minutes at 37°C; 5. Aspirate and wash 5 times; 6. Add 90 µL Substrate Solution. Incubate 10-20 minutes at 37°C; 7. Add 50 µL Stop Solution. Read at 450 nm immediately.

Stability: The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

Restrictions: For Research Use Only. Not for use in diagnostic procedures, drug use, or for administration to humans or animals.

Quality Systems: The kit is manufactured at ISO 9001 and ISO 13485 certified facilities.

Quality Assurance: Biomatik ELISA Kits are not typically pre-assembled as finished products due to limited shelf life. Before shipping, each kit is assembled and tested to ensure that it meets specifications before shipping. Minor changes may occur to the Detection Range, Sensitivity, and Precision. All kits are tested to confirm that they fall within their defined Inter- and Intra- assay coefficient of variation. Please always refer to the hard copy manual included in The kitbefore experiment.
