Cobas e411 Principle?



The Cobas e411 immunoassay analyzer operates on the principle of electrochemiluminescence (ECL). This technology combines the sensitivity of electrochemical detection with the specificity of chemiluminescence. Below is a detailed explanation of the ECL principle and how it is applied in the cobas e411:

Electrochemiluminescence (ECL) Technology

Binding Reaction:

  • The ECL process begins with the binding of an analyte (the substance to be measured) in the patient sample to a specific antibody or antigen that is coated on a solid phase (e.g., magnetic beads).
  • This binding reaction forms an immune complex. The solid phase is then washed to remove unbound substances.

Signal Generation:

  • A second antibody, labeled with a ruthenium complex (a chemiluminescent label), binds to the immune complex.
  • This creates a "sandwich" complex: a solid phase-analyte-labeled antibody.

Electrochemical Reaction:

  • The immune complex is transferred to a measuring cell where it is exposed to a voltage.
  • The voltage induces an electrochemical reaction in the ruthenium label, causing it to emit light (chemiluminescence).

Detection:

  • The emitted light is detected by a photomultiplier tube (PMT) or another type of light detector.
  • The intensity of the light emitted is directly proportional to the concentration of the analyte in the sample.

Quantification:

  • The analyzer uses a calibration curve to convert the light signal into a quantitative result.
  • This result is then displayed on the screen and can be printed or transmitted to a laboratory information system (LIS).


Advantages of ECL Technology in Cobas e411

High Sensitivity and Specificity:
  • ECL technology is highly sensitive and capable of detecting low levels of analytes with great accuracy.
  • The specificity of the antibody-antigen reaction ensures that only the target analyte is measured, reducing the likelihood of cross-reactivity.

Wide Dynamic Range:

  • ECL allows for the detection of a wide range of analyte concentrations, from very low to very high levels, without the need for multiple dilutions.

Rapid Results:

  • The electrochemical reaction and light detection are rapid, enabling quick turnaround times for test results.

Stability and Reproducibility:

  • The ECL process is highly reproducible, providing consistent results over multiple runs.
  • The stability of the ruthenium label and the solid-phase reagents ensures reliable performance over time.



Steps in the Cobas e411 Immunoassay Process

Sample Preparation:

  • Patient samples are prepared and loaded into the analyzer.
  • Reagents and calibrators are also loaded as required for the specific tests to be performed.

Automated Sample Handling:

  • The Cobas e411 automatically handles sample aspiration, mixing, and dispensing.
  • The samples are transferred to the reaction cells for the immunoassay process.

Immune Reaction:

  • The specific antibody or antigen-coated beads bind with the target analyte in the sample.
  • The immune complexes are formed and washed to remove unbound substances.

Signal Generation and Detection:

  • The labeled antibody binds to the immune complex.
  • The complexes are transferred to the measuring cell, where the ECL reaction occurs.
  • The emitted light is detected and quantified.

Result Calculation and Reporting:

  • The analyzer calculates the concentration of the analyte based on the light signal and the calibration curve.
  • The results are displayed, printed, or transmitted to the LIS for review and interpretation by the laboratory staff.
