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]

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]

Plasmid (pUC series) containing genomic DNA fragments are maintained in E. coli strain DH5aTM. The E. coli cultures are routinely cultured at 37 C on Luria-Bertani (LB) agar on or in LB broth containing Ampicillin (30 µg/ml) or Carbenicillin (50 µg/ml broth, 100 µg/ml agar). E. coli strains are usually preserved in stab agar or glycerol for mid-term storage and lyophilized for long-term storage. - [Read Maintenance of Probes in Bacteria Including Escherichia coli Protocol]

Quick and reliable method to analyze meiotic segregation patterns in Coprinus cinereus using the polymerase chain reaction. The advantages of this method include: 1. The tissue is grown and lyophilized in the same tube, which facilitates the simultaneous analysis of many segregants. 2. Only one extraction step is necessary. 3. The markers are scored by gel electrophoresis, thereby bypassing Southern analysis. - [Read Method to Analyze Meiotic Segregation Patterns in Coprinus cinereus Using PCR]

Great peptide storage information. Lerner. Peptides are provided as lyophilized product that should be stored as dry powder at -20°C to -70°C in a desiccator, if possible. After lyophilization, peptides retain significant amounts of water. Peptides are slowly degraded particularly the cysteine-containing peptides are oxidized over time at -20°C. - [Read Peptide Storage Information]

This protocol describes the preparation of concatamerized oligonucleotides and their coupling to cyanogen-bromide-activated Sepharose. The procedure uses a commercially activated resin, which can be purchased as a lyophilized powder. Keith Brocklehurst et al. - [Read Preparation of DNA Affinity Resin - Subscription Required]

DNA isolation method yields an average of 0.6 micrograms of genomic DNA that is suitable for Southern analysis or PCR. Starting with fresh mycelium, 20 to 40 samples can be processed in approximately two hours. Better yields (about 5 micrograms) may be obtained by suspending approximately 100 microliters of ground lyophilized mycelium in 500 microliters of isolation buffer and following the protocol. - [Read Small Scale DNA Preps for Neurospora crassa Protocol]
