How it works
Assay principle
Insulin is measured using a sandwich immunoassay of two monoclonal antibodies, one labelled with Cryptate (donor) and the other with XL665 (acceptor). The intensity of the FRET signal obtained is proportional to the concentration of insulin in the sample.
Assay protocol
10 µL of cell supernatants are supplemented with 10 µL of acceptor-labelled antibodies and 5 µL of donor-labelled antibodies (or 15 µL of pre-mixed reagents for a single dispensing step). The mix is then incubated from 4h to overnight at RT and results are read on an HTRF compatible reader.
Assay details
Sensitivity
The detection limit* is calculated as two standard deviations above the Calibrator 0. The HTRF® Insulin assay was calibrated against the NIBSC international standard 66/304. The following equivalence was found: 1 ng Insulin HTRF® represent 1 ng Insulin NIBSC 66/304 (i.e.: 2.3x10-05 IU). Samples were incubated overnight at room temperature. The assay ranges from 0,24 to 8 ng/mL and the detection limit measured was 0,064 ng/mL.

Correlation with leading ELISA
The HTRF Mouse serum insulin assay showed an excellent correlation to the leading absorbance and chemiluminescent ELISA, both on sera with low titers and high titers of insulin. With a slope of 1.1 and 0.9 respectively, the regression line was close to the ideal line, demonstrating the assay reliability.
Assay validation
Validation on normal mouse serum
C57BL/6J mice were randomized into two groups of 7 animals. One group was fasted overnight while the second one was normally fed. The mice were sacrificed and the blood was collected for serum preparation. The insulin concentration was determined in each sample using the HTRF Mouse Serum Insulin kit reagents.
Validation on diabetic mouse plasma
A group of five db/db diabetic male mice and a group of five db/+ control male mice were fasted overnight. The mice were sacrificed and the blood was collected through cardiac puncture for K3 EDTA-plasma preparation. The insulin concentration of each sample was determined using the HTRF Mouse Serum Insulin kit reagents.
Validation on obese mouse serum
A group of eight ob/ob obese mice and a group of eight ob/+ control mice were sacrificed and the blood was collected through cardiac puncture for serum preparation. The insulin concentration of each sample was determined using the HTRF Mouse Serum Insulin kit reagents.
