  1. Adaltis S.r.l. YOUR LABORATORY ON A FINGERTIP April 2011

  2. System Description Eclectica™ is a fully automated bench top analyzer able to perform, in an unique instrument, ImmunoAssay (IA) &Clinical Chemistry (CC) tests by using dedicated reagents. 1

  3. Instrument Description EclecticaTM is: very small-sized: 82 cm wide, 66 cm deep, 54 cm high highly compact:all in 0.54 m2 no hydraulic or wall connections are required EclecticaTM is suitable for laboratories of different dimensions and can be easily placed on every lab bench 2

  4. Instrument Description • Thermal printer • (real time results) • Touch screen Waste tank Common Reagents Drawer Protected working area: Reagent carrousel IA controls and Stds carrousel Sample Plate Reaction plate Dispensing & washing devices Reading chamber Smart card reader USB port • Keyboard with trackball 3

  5. Immunoassay: method description ECLECTICA™ uses a well-tested immunoreaction scheme based on immunoassays with magnetic particles. The separation method is so versatile that it allows to perform different assay schemes with the same separation reagent: • Direct Immunoenzymatic Assay (IEMA) • Competitive Immunoenzymatic Assay (EIA) 4

  6. Immunoassay: method description • Immunocomplex formation (first incubation @ 37 °C with shaking) • Immunocomplex separation through magnetic particles (second incubation @ 37 °C with shaking) • Washing • Substrate adding (third incubation @ 37 °C with shaking) • Colour development (with shaking) • Magnetic particles separation and colour reading (in flow cells) 5

  7. Data Management • Reading : 546 (main) / 492 (over range) nm • Over range OD is converted through an instrument dependant factor • Conversion factor is determined during QC procedures for each machine 6

  8. Data Management Abs Wavelength (nm) Phenolphtalein absorption spectrum 7

  9. Immunoassay Calibration Master curve is stored into the smart card of each specific reagents and it is verified by a two points calibration procedure Frequency of two point verification: every 2 - 4 weeks (test dependant) 8

  10. Immunoassay Calibration Checking the Curve CASE#1:C1 & C2 within calculation threshold → the master curve is left as it is CASE#2:C1 & C2 within the acceptance threshold → the master curve is accepted and adjusted CASE#3:C1 & C2 are outside the acceptance threshold → Invalid curve → troubleshoot and repeat controls OR perform 6 points standardization 9

  11. Immunoassay Calibration CALIBRATION. WHEN? • New kit lot (specific or common reagents) • Calibration expired • The quality control sera outside acceptability ranges • It is required by regulatory 10

  12. Immunoassay and Clinical Chemistry Immunoassay • Validated and closed system • Immediate availability of kits and consumables Clinical chemistry • Validated and closed system • Immediate availability of kits and consumables 11

  13. Clinical Chemistry: Method Description Clinical chemistry reactions can be classified in three main groups: • End-point calculations • Kinetic • Fixed time 12

  14. Lambert and Beer law The principle on which the photometry is based on is “If a monochromatic radiation passes through a solution the absorption takes place. The amount of radiation absorbed (ABSORBANCE) is directly proportional to the thickness and to the concentration of the solution” A = ε b c ε = wavelength-dependent molar coefficient with units of L mol-1cm-1 b = is the path length c = concentration

  15. Lambert and Beer law The absorption of the solution is called: ABSORBANCE=OPTICAL DENSITY=EXTINCTION Measuring at the same λ the absorbance of a solution with known concentration A cal (Calibrator) and that one of a solution with an unknown concentration A* it is that:
