Perform Electrophoresis Tip: Monitor migration with a pre-stained molecular weight marker. The immunoassay uses a membrane made of nitrocellulose or PVDF (polyvinylidene fluoride). Prepare Samples Tip: Determine protein concentration with an assay.

Finally, we provide insight on how to deal with complex samples, as well as future prospects in the field of phage quantification.īacteriophage detection double agar overlay assay enumeration molecular biology real-time PCR sequencing.Ĭopyright © 2020 Ács, Gambino and Brøndsted. Western blotting is a technique that uses specific antibodies to identify proteins that have been separated based on size by gel electrophoresis. Here, we describe the methods currently used for phage detection and enumeration and highlight their advantages as well as their limitations. While molecular methods cannot discriminate between viable and non-infectious phages, the traditional techniques for counting infectious phages can be time consuming and poorly reproducible. Procedure Save original western blot image in JPEG, PNG or TIFF on your computer. There are many applicable methods, but care should be taken considering the measured object (infectious phage, whole phage particle or nucleic acid and proteins) and the concept behind the technique to avoid misinterpretations. This is a simple protocol to quantitatively analyze western blot. Application of phages as alternative antimicrobials to combat pathogenic bacteria and their association to a healthy gut microbiome has prompted a need for precise methods for detection and enumeration of phage particles.
