Calcitonin (CT) BioAssay™ ELISA Kit (Rat)

Blue Ice

38220000

The Rat Calcitonin (CT) ELISA Kit is a competitive inhibition immunoassay for the in vitro quantitative measurement of CT in rat serum, plasma, tissue homogenates, cell culture supernatants and other biological fluids.

Detection Range:
12.35-1, 000pg/ml

Sensitivity:
5.14pg/ml

Precision:
Intra-Assay CV: <10%
Inter-Assay CV: <12%

Test Principle:
This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific for CT has been pre-coated onto a microplate. A competitive inhibition reaction occurs between biotin-labeled CT and unlabeled CT (standards or samples) with the pre-coated antibody specific for CT. 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 inversely proportional to the concentration of CT in the sample. After addition of the substrate solution, the intensity of color developed is inversely proportional to the concentration of CT in the sample.

Storage and Stability:
Store *023845A, *023845B, *023845D and *023845E at -20°C. Store all the other components at 4°C. Unused kit is stable for 6 months. Once kit components are opened, it is highly recommended to use remaining reagents within 1 month provided this is within the expiration date of the kit. For maximum recovery of product, centrifuge the original vials after thawing and prior to removing the cap.
