Category: Viral Manipulation Protocols: Phage Lamda Manipulation Protocols

Formamide can be used instead of proteinase K to dissociate bacteriophage {lambda} coat proteins from the viral {lambda}. The procedure is rapid and works best with large-scale preparations of bacteriophage {lambda}. - [Read Extraction of Bacteriophage lambda DNA from Large-scale Cultures Using Formamide Protocol]

Category: Viral Manipulation Protocols: Phage Lamda Manipulation Protocols

DNA is best isolated from bacteriophage lambda particles by digesting the viral coat proteins with a powerful protease such as proteinase K, followed by extraction with phenol:chloroform. This procedure is easily adapted for use with smaller-scale preparations of bacteriophage lambda. - [Read Extraction of Bacteriophage lambda DNA from Large-scale Cultures Using Proteinase K and SDS Protocol]

Category: DNA Protocols: DNA Extraction Protocols

DNA isolation from various fungal species including: Cochliobolus, Aternaria, and Fusarium. Key steps: (1) the use of young lyophilized mycelial mats - yield less contaminating carbohydrates; (2) proteinase K in the extraction buffer to destroy DNases (f - [Read Fungal DNA Isolation Method]

Category: Nucleic Acid Purification Protocols: DNA Isolation Protocols

Protocol for fungal DNA isolation. The key elements in this prep are (1) the use of young lyophilized mycelial mats....young mats (4 days growth for C. carbonum)...yield less contaminating carbohydrates and other misc. junk (2) lots of proteinase K in the extraction buffer to kill Dnases (final =0.3mg/ml). - [Read Fungal DNA Isolation Protocol]
