Preparation of Phage Lysates (Goldberg Lab) Very nice and detailed protocol including recipes for media preparation
Gel Assay to Determine DNA Content of Phage Lysates (Donis Keller Lab) A crude lysate gel assay can be performed to roughly quantitate the DNA in lysates. This is often a valuable time saving step to determine if the phage yield is sufficient to warrant continuing the procedure
Titering Lambda Phages (Donis Keller Lab) This procedure is used to find the number of viable phage particles in a lysate. The phage lysate is serially diluted and ...
Phage Plate Stock Lysates (Donis Keller Lab) To prepare phage lysates to be used for small or large scale phage DNA preps. This method usually produces lysates with titers of 2-8x10e10 pfu/ml.
Assay for Phage Containing the ?- Galactosidase Gene (Donis Keller Lab) This assay is used when working with phage vectors carrying the beta-galactosidase gene (often used for immunological screening). If the cloning event disrupts a normally functional copy of the gene in the vector the resulting plaques would appear clear in the assay. If the phages contain a functional beta-galactosidase gene they will form blue rings around their plaques.
