Kinetic analysis of biomolecular interactions are powerfully used to quantify the
binding kinetic constants for the determination of a complex formed or
dissociated within a given time span. Surface plasmon resonance biosensors
provide an essential approach in the analysis of the biomolecular interactions
including the interaction process of antigen-antibody and receptors-ligand. The
binding affinity of the antibody to the antigen (or the receptor to the ligand)
reflects the biological activities of the control antibodies (or receptors) and
the corresponding immune signal responses in the pathologic process. Moreover,
both the association rate and dissociation rate of the receptor to ligand are the
substantial parameters for the study of signal transmission between cells. A
number of experimental data may lead to complicated real-time curves that do not
fit well to the kinetic model. This paper presented an analysis approach of
biomolecular interactions established by utilizing the Marquardt algorithm. This
algorithm was intensively considered to implement in the homemade bioanalyzer to
perform the nonlinear curve-fitting of the association and disassociation process
of the receptor to ligand. Compared with the results from the Newton iteration
algorithm, it shows that the Marquardt algorithm does not only reduce the
dependence of the initial value to avoid the divergence but also can greatly
reduce the iterative regression times. The association and dissociation rate
constants, ka, kd and the affinity parameters for the biomolecular interaction,
KA, KD, were experimentally obtained 6.969×10(5) mL·g(-1)·s(-1), 0.00073 s(-1),
9.5466×10(8) mL·g(-1) and 1.0475×10(-9) g·mL(-1), respectively from the injection
of the HBsAg solution with the concentration of 16 ng·mL(-1). The kinetic
constants were evaluated distinctly by using the obtained data from the
curve-fitting results.
