A simple and rapid nephelometric procedure for fibronectin.

P H Cuigniez, M Biesbrouck, J van Hooren

    Annals of Clinical Biochemistry
    |September 1, 1985
    PubMed
    Summary

    A new nephelometric assay accurately measures plasma fibronectin. This method is faster, cheaper, and more specific than current turbidimetric techniques, requiring less antiserum.

    Area of Science:

    • Clinical Chemistry
    • Immunology

    Background:

    • Plasma fibronectin is a crucial glycoprotein involved in cell adhesion and wound healing.
    • Accurate measurement of plasma fibronectin is important for diagnosing and monitoring various medical conditions.
    • Existing turbidimetric methods for fibronectin quantification can be time-consuming and require significant reagent volumes.

    Purpose of the Study:

    • To describe a novel nephelometric assay for quantifying plasma fibronectin.
    • To evaluate the performance characteristics of this new assay.

    Main Methods:

    • A nephelometric assay utilizing the Beckman ICS platform was developed.
    • Commercially available reagents from Boehringer were employed.
    • Assay performance was assessed for simplicity, speed, cost-effectiveness, specificity, and precision.

    Main Results:

    • The nephelometric assay demonstrated simplicity, rapidity, and cost-effectiveness.
    • High specificity was achieved in plasma fibronectin measurement.
    • Within-run variation ranged from 4.3% to 7.8%.
    • The assay requires only 30 microL of antiserum per measurement, compared to 100 microL for turbidimetric methods.

    Conclusions:

    • The described nephelometric assay provides a superior alternative for plasma fibronectin measurement.
    • This method offers significant advantages in terms of efficiency and reagent consumption.
    • The assay is suitable for routine clinical laboratory use.
