Application

The pH values of all buffers are temperature and concentration dependent. For Tris buffers, pH increases about 0.03 unit per °C decrease in temperature, and decreases 0.03-0.05 unit per ten-fold dilution.
For precise applications, use a carefully calibrated pH meter with a glass/calomel combination electrode.
Buffering agent in incubation mixtures. It has also been used as a component of lysis and TE (Tris-EDTA) buffer.

Secretome analysis is crucial to unravel extracellular processes. However, secreted proteins are difficult to detect in mass-spectrometry-based analysis due to contamination of serum proteins deriving from cell culture media and to high glycosylation, which hampers tryptic digestion. Secret3D workflow is...

We describe here a streamlined procedure for targeting vector construction, which often is a limiting factor for gene targeting (knockout) technology. This procedure combines various highly efficient recombination-based cloning methods in bacteria, consisting of three steps. First step is the...

Protein lysine methylation mediates a variety of biological processes, and their dysregulation has been established to play pivotal roles in human disease. A number of these sites constitute attractive drug targets. However, systematic identification of methylation sites is challenging and...

Protein-DNA interactions are essential for establishing cell type-specific chromatin architecture and gene expression. We recently developed scDam&T-seq, a multi-omics method that can simultaneously quantify protein-DNA interactions and the transcriptome in single cells. The method effectively combines two existing methods: DNA...
