A dot blot (or slot blot) is a technique in molecular biology used to detect proteins. It represents a simplification of the western blot method, with the exception that the proteins to be detected are not first separated by electrophoresis. Instead, the sample is applied directly on a membrane in a single spot, and the blotting procedure is performed.

This invention relates to the field of clinical virus detection, and more particularly to a protein dot blot detection kit, detection method, and application for varicella-zoster virus (VZV). The kit includes: a solid-phase carrier membrane for binding and immobilizing proteins in the sample; a blocking agent for blocking non-specific binding sites on the solid-phase carrier membrane; a first antibody that specifically recognizes the VZV antigen; an enzyme-labeled second antibody that binds to the first antibody; and a chromogenic solution for generating a detection signal. This kit is based on protein dot blot technology, detecting proteins with high specificity and a low false-positive rate. The experimental cycle is short, taking only 2-3 hours from sample pretreatment to signal detection, much faster than virus culture (requiring 4-7 days) and PCR detection (although fast, prone to false positives or false negatives), providing rapid evidence for clinical treatment, and is particularly suitable for the diagnosis of acute herpes zoster.
