How do you check methylation status?
Currently, there are three primary methods to identify and quantify DNA methylation. These are: sodium bisulfite conversion and sequencing, differential enzymatic cleavage of DNA, and affinity capture of methylated DNA (1). Restriction enzyme based differential cleavage of methylated DNA is locus-specific.
In my opinion, you should purify phages. It may not be a good idea for TEM observation If you wanted to use phages directly from the lysate. If you want a good-quality picture, you may go through the CsCl gradient centrifugation method. You may try Phosphotungstic acid for better negative staining. I hope you got the better picture in TEM.
