Tryptase (EC 3.4.21.59) is the most abundant secretory granule-derived serine proteinase contained in mast cells and has been used as a marker for mast cell ...
Parts-per-million cube of relative abundance by mass of elements in an average adult human body down to 1 ppm. About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium ...
The detection of a protein in unexpected locations within cells, cell types, or tissues may suggest that a protein has a moonlighting function. Furthermore, the sequence or structure homology of a protein may be used to infer both primary functions as well as secondary moonlighting functions of a protein.
Trypsin digestion of extra cellular matrix is a common practice in cell culture. However, this enzymatic degradation of the cells can negatively effect cell viability and surface markers, especially in stem cells. There are gentler alternatives than trypsin such as Accutase which doesn't effect surface markers such as cd14, cd117, cd49f, cd292.
In cell biology, an organelle is a specialized subunit, usually within a cell, that has a specific function.The name organelle comes from the idea that these structures are parts of cells, as organs are to the body, hence organelle, the suffix -elle being a diminutive.
ATM serine/threonine kinase or Ataxia-telangiectasia mutated, symbol ATM, is a serine/threonine protein kinase that is recruited and activated by DNA double-strand breaks (canonical pathway), oxidative stress, topoisomerase cleavage complexes, splicing intermediates, R-loops and in some cases by single-strand DNA breaks.

The vault or vault cytoplasmic ribonucleoprotein is a eukaryotic organelle (a structure in the cells of multicellular organisms) whose function is not yet fully understood. . Discovered and isolated by Nancy Kedersha and Leonard Rome in 1986, [2] vaults are cytoplasmic structures (outside the nucleus) which, when negative-stained and viewed under an electron microscope, resemble the arches of ...
[1] Cellular respiration is a vital process that occurs in the cells of all [[plants and some bacteria ]]. [2] [better source needed] Respiration can be either aerobic, requiring oxygen, or anaerobic; some organisms can switch between aerobic and anaerobic respiration. [3] [better source needed]
