Definitions
- the present invention relates to a diagnostic method for detecting markers of disease and/or clinical and/or medical conditions in biological fluids, and the apparatus for use in such methods .
- Markers such as proteins or other entitities which are indicative of disease states or conditions are frequently present in biological fluids such as blood, serum or urine.
- icroalbuminuria or MATJ elevated levels of albumin in the urine
- MATJ elevated levels of albumin in the urine
- elevated levels >30 ⁇ g/ml
- albumin albumin in urine
- vascular permeability Increases in vascular permeability occur as a result of inflammatory and/or immune response to trauma or infection.
- MAU is being regarded as a general indicator of trauma (see Gosling, P., British Journal of Hospital Medicine, 1995, 54, p285-289) .
- the extent of microalbuminuria has been suggested as a predictor of the development of complications in the trauma patient. Rapid, bedside determination of microalbuminuria may allow the objective use of treatment for the recovery of seriously ill patients.
- microalbuminuria has widespread application for monitoring any severe inflammatory condition resulting as a consequence of e.g. major surgery, major trauma, burn injury, acute pancreatitis, bacteraemia, acute myocardial infarction and post respiratory/cardiac arrest therapy.
- Antibody-based precipitation methods for the detection of MAU are commercially available. These range from dipsticks to light-scattering assay's (e.g. Bayer DCA 2000). Available systems require skilled personnel, are relatively slow, and are not suitable for continuous monitoring.
- some - assay's require supporting equipment, are only semi- quantitative and require samples and/or reagents to be added manually.
- the present invention provides a method of diagnosing a disease state or condition, said method comprising contacting a sample of a biological fluid taken from a patient suspected of suffering from said disease state or condition with a specific binding agent for said agent, and assaying for the presence of a complex between said binding agent and said marker using an evanescent wave detection device.
- This method allows for the rapid and/or continuous monitoring of marker levels in biological fluids. Depending upon the nature of the marker, its presence or its presence at unusual levels (either elevated or depressed) may be indicative of a clinical problem.
- the assay may be carried out directly or competitively as would be understood in the art.
- the specific binding agent is immobilised on the detection surface of an evanescent wave detection device and the sample is then contacted with that surface.
- the evanescent field can then be monitored in order to determine the presence or amount of bound marker thereon.
- the detection surface of an evanescent wave detection device may have immobilised thereon a further binding agent such as an antibody, which binds the specific binding agent, in the absence of marker.
- a further binding agent such as an antibody, which binds the specific binding agent, in the absence of marker.
- the marker blocks the binding of specific binding agent to the further binding agent.
- specific binding agent __ is added to the sample to bind any marker present . Contact with the detection surface would mean that only residual unbound specific binding agent would become attached to the surface and affect the evanescent field. Thus the less bound agent is detected, the greater the amount of marker present in the sample .
- This option may be preferable where the marker is of low molecular weight and the specific binding agent is of relatively high molecular weight since evanescent wave devices have a higher detection efficiency for high molecular weight moieties .
- Suitable specific binding agents include antibodies, receptors, enzymes, oligonucleotides or any other bio reactive molecule depending upon the nature of the particular marker being detected, as well as binding fragments of any of these.
- the specific binding agent will be an antibody, enzyme or receptor or a binding fragment.
- the specific binding agent will comprise an antibody or binding fragments thereof such as F(ab) and F(ab') 2 fragments.
- Markers may comprise proteins, sugars, lipids or even DNA or RNA, depending upon the nature of the disease state or condition being detected. Generally, the marker will comprise a protein.
- the marker is preferably a high molecular weight, for example, having a molecular weight of greater than lOOODa.
- markers are detected readily using evanescent wave detectors.
- An example of such a marker is human serum albumin, which as discussed above, is a marker for inflammatory conditions when present at elevated levels in urine. Antibodies specific for this protein are available commercially.
- the detection method of the invention can be used to detect microalbuminuria as an indicator of an inflammatory condition, for example caused as a result surgery, trauma, burn injury, acute pancreatitis, bacteraemia, acute myocardial infarction or post respiratory/cardiac arrest therapy.
- the method of the invention can employ any evanescence based detector system which can directly measure for example antibody-antigen binding at a sensor through changes in local refractive index.
- Suitable evanescent wave detection devices for use in the method of the invention include a resonant mirror system (RM) , a planar optical waveguide device or a surface plasmon resonance detector.
- the evanescent wave detection device is a resonant mirror system (RM) .
- the RM instruments uses an evanescent field to measure small changes of refractive index at the sensor surface.
- the sensing element is an integrated optical chip consisting of a glass prism, a thin, low refractive index silica spacer layer and a thinner high refractive index waveguide layer (see Figure 1) .
- a beam of monochromatic light is directed at the prism/spacer interface above a critical angle, it undergoes total internal reflection.
- the light couples into the waveguide through the spacer layer via the evanescent field and propagates by multiple internal reflections before tunnelling back into the prism.
- the RM device measures the resonant angle at which resonant light and incident light is out of phase by a factor of ⁇ radians.
- the measured resonant angle is highly sensitive to changes in the refractive index within a few hundred nanometres of the sensor surface.
- Binding of ligands or markers to specific binding agents or recognition elements e.g. antibodies which have been immobilised on the sensor surface alters the refractive index of the surface and consequently the resonant angle of the sensing element .
- the specificity of the detection event is controlled by the specificity of the binding agent which is used.
- assay's using the method of the invention can be made specific for human albumin by the immobilisation of anti- human serum albumin ( ⁇ -HSA) antibodies on the sensor surface.
- ⁇ -HSA anti-human serum albumin
- Monoclonal ( ⁇ -HSA) antibodies are available commercially.
- monoclonal ( ⁇ -HAS) antibodies are immobilised on the sensor in an RM system.
- HSA present in samples applied to the sensor surface binds to the immobilised ⁇ -HSA antibodies with consequent effects on the refractive index of the sensor surface and the resonant angle of the sensor element .
- the change in resonant angle can be quantitated and used to determine the concentration of HSA in the sample.
- Sensors of a resonant mirror system having thereon, a specific binding agent for a biological disease marker, for example albumin, form a further aspect of the invention.
- multiple analytes or markers for example from 2 to 100 markers, could be detected simultaneously by providing more than one specific binding agents appropriately configured on the surface of the sensor of the detector.
- the method of the invention could be used as the basis for the rapid screening system for a range of medical conditions or diseases.
- the method further provides a means of continuously monitoring a patients progress, for example in an intensive care situation, where for example a urine stream from a catherized patient may be passed continuously across the detector in order to continually monitor the patients condition and allow a rapid response.
- the detection device may be provided with a pump in order to allow a continuously stream of liquid to pass over the detector surface .
- Figure 1 shows diagrammatically the principles of operation of a resonant mirror system.
- the detector used was a continuous flow, multi-analyte resonant mirror (RM) system. This was constructed by Affinity Sensors and is based on the company's commercially available manual, double channel IAsys system outlined in Patent application WO
- ⁇ -HSA antibody Biogenesis, 0220-0704
- HSA concentration ⁇ g/ml
- Results were achieved within -10 seconds and could be configured for continuous monitoring of HSA levels. Further work demonstrated that the assay was reproducible (10 consecutive assays) at high (292 +/-27 ⁇ g/ml, mean +/- SD) and low (7.8 +/- 1.4 ⁇ g/ml, mean +/- SD) concentrations. Once coated, the sensor surfaces could be re-used and stored for a - least a month at 4°C without affecting results.
