Mononuclear phagocyte progenitor cells derived from femoral and tibial bone marrow are propagated in the presence of M-CSF. This macrophage growth factor is secreted by L929 cells and is used in the form of L929 cell conditioned medium. The progenitor cells proliferate and differentiate through monoblast, promonocyte and monocyte stages before maturing to macrophages. At this time the cells become firmly adherent to the culture vessel. - [Read Isolation and Culture of Mouse Bone Marrow-Derived Macrophages Protocol]
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]
Magnetic DNA affinity purification of yeast transcription factor tau--a new purification principle for the ultrarapid isolation of near homogeneous factor. Gabrielsen et al. 1989 - [Read DNA-Binding Protein Purification with Dynabeads.]
This protocol describes the isolation of fibroblasts from mouse embryos. Mouse embryonic fibroblast (MEF) cells are used as a feeder layer for the culture of mouse embryonic stem (ES) cells to help maintain them as pluripotent stem cells. The inhibition of ES-cell differentiation provided by the MEF feeders appears to be due to their production of leukemia inhibitory factor (LIF). - [Read Isolation and Freezing of Primary Mouse Embryonic Fibroblasts (MEF) For Feeder Plates]
The protocol includes: organelle isolation, deoxyribonuclease treatment, lysis, deproteinisation and a final DNA purification with sodium dodecyl sulphate and potassium
acetate. The organelle DNA yield is 5–10 micrograms per gram of tissue and the DNA is fully restrictable. The technique is inexpensive and appropriate for the isolation of multiple
samples of organelle DNA from a small amount of tissue. - [Read A Method for Isolation of Chloroplast DNA and Mitochondrial DNA from Sunflower]
A Single Stranded Plasmid DNA Isolation Protocol describing the production and isolation of single-stranded DNA (ssDNA) using bacteriophagemid-containing bacteria and helper phage. Infection of the host cells with helper phage allows for packaging of ssDNA into bacteriophage. The ssDNA can then be isolated from phage particles.
A single step RNA isolation protocol using Phenol Chloroform Extraction and Acid Guanidinium Thiocyanate. This RNA isolation method uses the fact that guanidinium thiocyanate can simultaneously lyse the cells and inactive cellular RNAses during the initial RNA isolation step allow a single step in the method.
The DNA Ligation protocol described here contains the steps required to join together using ligase enzyme both plasmid DNA and insert DNA fragments in order to create a new plasmid. This new ligated plasmid can be transformed after into competent bacteria to produce DNA for mini, midi or maxi-prep isolation.
This protocol describes the electroporation of the BMH 81-17 mut S strain that is recommended for tranformation of the site directed mutagenesis of dsDNA (See Protocol on Site-Directed Mutagenesis on Double Stranded DNA). BMH 81-17 mut S are a mismatch repair defective (mut S) Escherichia coli strain. The probability that the two mutations will cosegregate during the first round of DNA replication is increased in this strain.
