IMMULITE/IMMULITE 1000 Calcitonin is a solid-phase, enzyme-labeled, two-site chemiluminescent immunometric assay. The solid-phase, a polystyrene bead enclosed within an IMMULITE/IMMULITE 1000 Test Unit, is coated with a monoclonal murine antibody specific for calcitonin. While the patient serum sample and alkaline phosphatase-conjugated to polyclonal goat anti-calcitonin are incubated for approximately 30 minutes at 37℃ in the Test Unit with intermittent agitation, calcitonin in the sample is bound to form an antibody sandwich complex. Unbound enzyme conjugate is then removed by a centrifygal wash, after which substrate is added and the Test Unit is incubated for a further 10 minutes. The chemiluminescent substrate, a phosphate ester of adamantyl dioxetane, undergoes hydrolysis in the presence of alkaline phosphatase to vield an unstable intermediate. The continuous production of this intermediate results in the sustained emission of light, thus improving precision by providing a window for multiple readings. The bound complex and thus also the photon output, as measured by the luminometer - is proportional to the concentration of calcitonin in the sample. {2}------------------------------------------------ IMMULITE 2000 Calcitonin is a solid-phase, enzyme-labeled, two-site chemiluminescent immunometric assay. The solid-phase, a polystyrene bead, is coated with a monoclonal murine antibody specific for calcitonin. While the patient serum sample and alkaline phosphatase-conjugated to polyclonal goat anti-calcitonin are incubated for approximately 30 minutes at 37℃ in the Reaction Tube with intermittent agitation, calcitonin in the sample is bound to form an antibody sandwich complex. Unbound enzyme conjugate is then removed by a centrifugal wash, after which substrate is added and the Reaction Tube is incubated for a further 5 minutes. The chemiluminescent substrate, a phosphate ester of adamantyl dioxetane, undergoes hydrolysis in the presence of alkaline phosphatase to yield an unstable intermediate. The continuous production of this intermediate results in the sustained emission of light, thus improving precision by providing a window for multiple readings. The bound complex and thus also the photon output, as measured by the luminometer - is proportional to the concentration of calcitonin in the sample. Nichols Advantage Calcitonin assay is a two-site chemiluminescence immunoassay for the measurement of calcitonin in human serum. It utilizes two mouse monoclonal antibodies to human calcitonin. One of the mouse monoclonal antibodies is labeled with acridinium ester for detection, while a second mouse monoclonal antibody is coupled to biotin. Calcitonin is "sandwiched" between these antibodies. The sample containing calcitonin is incubated simultaneously with both antibodies. The formation of a soluble sandwich complex occurs only in the presence of calcitonin molecules, which bridge the two antibodies. Therefore, only peptides that bridge these two antibodies can be quantitated. After an initial incubation period, steptavidin coated magnetic particles are added to the reaction mixture and a second incubation follows. This allows for a highly specific and efficient means of binding the sandwich complex to the solid phase via the high affinity interaction between biotin and streptavidin. Free labeled antibody is separated from the labeled antibody bound to the magnetic particles by aspiration of the reaction mixture and subsequent washing. The wells containing the washed magnetic particles are transported into the system luminometer, which automatically injects Trigger 2, initiating the chemiluminescence reaction. The light is quantitated by the luminometer and expressed as RLU. The amount of bound labeled antibody is directly proportional to the concentration of calcitonin in the sample. {3}------------------------------------------------ ### Performance Equivalence: Diagnostic Products Corporation asserts that the IMMULITE/IMMULITE 1000 Calcitonin and IMMULITE 2000 Calcitonin produce substantially equivalent results to other commercially marketed Calcitonin assays, such as Nichols Advantage™ Calcitonin used with the Nichols Advantage™ Specialty System. Each product is designed for the quantitative measurement of calcitonin in human serum. Each product is intended strictly for in vitro diagnostic use as an aid in the diagnosis and treatment of diseases involving the thyroid and parathyroid glands, including carcinoma and hyperparathyroidism. ### Method Comparison The IMMULITE/IMMULITE 1000 Calcitonin procedure was compared to a commercially available assay (Nichols Advantage) on 53 patient samples, with calcitonin concentrations ranging up to approximately 1,200 pg/mL. Linear regression analysis vielded the following statistics. | | (IMMULITE/IMMULITE 1000) = 0.71 (Nichols) + 4.2 pg/mL | r = 0.990 | |--|-------------------------------------------------------|-----------| | | Mean = 155 pg/mL (IMMULITE/IMMULITE 1000) | | 155 pg/mL (IMMULITE/IMMULITE 1000) Means: 212 pg/mL (Nichols) The IMMULITE 2000 Calcitonin procedure was compared to a commercially available assay (Nichols Advantage) on 67 patient samples, with calcitonin concentrations ranging up to approximately 1,500 pg/mL. Linear regression analysis yielded the following statistics. (IMMULITE 2000) = 0.81 (Nichols) - 0.4 pg/mL r = 0.982 Means: 193 pg/mL (IMMULITE 2000) 239 pg/mL (Nichols) #### Conclusion: The data presented in this summary of safety and effectiveness is the data that the Food and Drug Administration used in granting DPC substantial equivalence for IMMULITE® IMMULITE® 1000 Calcitonin and IMMULITE® 2000 Calcitonin. {4}------------------------------------------------ ### DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/4/Picture/1 description: The image shows the seal of the U.S. Department of Health and Human Services.
