    Area of Science:

    • Biochemistry
    • Immunology
    • Analytical Chemistry

    Background:

    • Radioimmunoassays (RIAs) are crucial for quantifying antigens.
    • Traditional methods for separating bound from free antigen can be time-consuming.
    • Efficient separation is key to RIA sensitivity and accuracy.

    Purpose of the Study:

    • To develop a faster and equally accurate radioimmunoassay for acyclovir.
    • To improve the separation of bound antigen from free antigen.

    Main Methods:

    • Investigated charcoal adsorption for unbound acyclovir separation.
    • Compared this method to ammonium sulfate precipitation of bound acyclovir.
    • Evaluated the impact on RIA speed, sensitivity, and accuracy.

    Main Results:

    • Charcoal adsorption of unbound acyclovir provided efficient separation.
    • The new RIA method was quicker than the previous one.
    • The sensitivity and accuracy of the charcoal adsorption RIA were comparable to the established method.

    Conclusions:

    • Charcoal adsorption is a superior method for separating unbound acyclovir in RIAs.
    • This technique offers a faster, yet equally sensitive and accurate, alternative for antigen-bound/free separation.
