• To address common difficulties encountered by students and researchers in performing plaque assays.
• To introduce refined techniques for improved accuracy and reproducibility.

Main Methods:

• Modification of standard plaque assay methodology for herpes simplex virus.
• Detailed instructions on optimal host cell handling to prevent disruption.
• Utilization of a viscous medium superior to agarose for limiting virion diffusion.
• Implementation of a simplified fixation and staining technique for consistent outcomes.
• Inclusion of a video demonstration to illustrate nuanced procedural aspects.

Main Results:

• The refined protocol facilitates easier visualization and mastery of virus plaquing techniques.
• The improved viscous medium effectively controls virion spread, enhancing plaque definition.
• The simplified fixation and staining procedure yields reliably reproducible results.
• The accompanying video aids in understanding subtle yet critical procedural details.

Conclusions:

• This enhanced protocol simplifies virus plaque assays, particularly for herpes simplex virus.
• The described modifications improve the accuracy, reproducibility, and ease of learning the technique.
• The resource is valuable for students and researchers seeking to effectively perform plaque assays.
