Tetraethylenepentamine (TEPA) is an organic compound and is in the class of chemicals known as ethyleneamines. It is a slightly viscous liquid and is not colorless but, like many amines , has a yellow color.
S. cerevisiae septins revealed with fluorescent microscopy utilizing fluorescent labeling. In molecular biology and biotechnology, a fluorescent tag, also known as a fluorescent label or fluorescent probe, is a molecule that is attached chemically to aid in the detection of a biomolecule such as a protein, antibody, or amino acid.

SNAP-tag reaction scheme. SNAP-tag® is a self-labeling protein tag commercially available in various expression vectors. SNAP-tag is a 182 residue polypeptide (19.4 kDa) that can be fused to any protein of interest and further specifically and covalently tagged with a suitable ligand, such as a fluorescent dye.
There are currently six varieties of TMT available: TMTzero, a non-isotopically substituted core structure; TMTduplex, an isobaric pair of mass tags with a single isotopic substitution; [5] TMTsixplex, an isobaric set of six mass tags with five isotopic substitutions; [6] [non-primary source needed] TMT 10-plex – a set of 10 isotopic mass tags which use the TMTsixplex reporter region, but ...
Polyethylenimine (PEI) or polyaziridine is a polymer with repeating units composed of the amine group and two carbon aliphatic CH 2 CH 2 spacers. Linear polyethyleneimines contain all secondary amines, in contrast to branched PEIs which contain primary, secondary and tertiary amino groups.
This complexity is likely why the Trump administration has tried to use a very specific definition of biological sex that avoids talking about genitals, chromosomes or anything other than ...
Photoaffinity labeling is a chemoproteomics technique used to attach "labels" to the active site of a large molecule, especially a protein.The "label" attaches to the molecule loosely and reversibly, and has an inactive site which can be converted using photolysis into a highly reactive form, which causes the label to bind more permanently to the large molecule via a covalent bond.
