3,200+ step-by-step lab protocols and SOPs for cell culture, staining, PCR, protein work and microbiology, with reagents, conditions and evaluation criteria.
Affinity chromatography methods can virtually purify maltose-binding fusion proteins into single components. Maltose-binding protein self (MBP) is a periplasmic
The exogenous protein expressed in the pGEX vector is fused to glutathione S transferase and can therefore be purified by glutathione-agarose affinity chromatog
The following method is a modification of the phosphotransformation method established by Graham and Van der Eb (1973), in which high molecular weight genomic D
Analysis of promising genomic or cDNA clones usually begins with digestion of small preparations of λ phage DNA with restriction enzymes and analysis of the di
Two forms of the classical DEAE-dextran transfection method are introduced here. The first one (the main option), in which the cells are exposed to high concent
This protocol describes a mapping method for identifying protein binding sites on radiolabeled DNA fragments. The protocol uses DNAase I to cut the DNA, whereas
The gel-blocking assay for analyzing DNA-binding proteins was invented by Fried and Crothers (1981) and was the first to provide a dynamic method for analyzing
The following scheme is based on methods developed by Horch et al. (1999), Sanford et al. (1993), publications from major gene gun manufacturers (US/EG Bulletin
The Polybrene and DMSO transfection method described below is a modification of the method of Aubin et al. (1997). Using this method, plasmid DNA can be efficie
