The phrase
"to label the protein" means attaching a specific marker or tag to a protein molecule in order to track or detect it in a scientific experiment or study.

Arla Foods Ingredients showcased a clean
label protein bar prototype made with milk from grass - fed cows without any added hormones at IFT held in Las Vegas last month.
Both PALM and stimulated emission depletion (STED) microscopy, the other super-resolution technique recognized with the 2014 Nobel Prize, illuminate samples with so much light that
fluorescently labeled proteins fade and the sample is quickly damaged, making prolonged imaging impossible.
Using the kits, you can quickly and easily
label proteins in lysates or purified proteins with near - infrared CF ® dyes before electrophoresis and blotting.
The new beef items will join the organic chicken and NAE poultry (No Antibiotic Ever) lines to significantly increase Essentia's line of clean
label protein solutions.
Due to loose labeling requirements from the FDA, companies can
easily label their protein bars as «health food» or «nutrition bars».
15N - labelled and 13C,15N -
labelled proteins for NMR experiments were purified (without His - tag) from cells grown in M9 minimal medium containing either 15NH4Cl or 15NH4Cl and (13C6) D - glucose (Cambridge Isotopes Laboratories) as the sole sources of nitrogen and carbon, respectively.
These include more sensitive mass spectrometry for detecting, identifying and quantifying protein molecules, electron microscopy for visualizing an assortment of components of the nano - machine that transports toxins, and fluorescence confocal microscopy, which can
label proteins with light emitting dyes.
By tracing the integration of
radioactively labelled proteins into the inner mitochondrial membrane, they were able to prove that OXA is necessary for this process.
The Drosophila embryos in the study contained a pair of
fluorescent labeled proteins: a developmentally essential and ubiquitously present protein called Rho GTPase Cdc42 (cell division control protein 42), labeled with green fluorescent tag and its alleged signaling partner, the regulatory protein WASp (Wiskot - Aldrich Syndrome protein), labeled with red fluorescent tag.
However, when they repeated the
experiment labelling the protein rather than the DNA of the original virus, they found that the viruses produced were not radioactive.
The researchers used an antibody that
labels the proteins made by two closely linked homeotic genes, Ubx and abdA, to show in which segments of the embryo the genes are turned on.
Under a microscope, these GFP -
labeled proteins shine in a steady glow, allowing scientists to easily track and observe the proteins» movements and behaviors.
While the immobilized molecules are effectively excited by external light such as a laser beam, the excitation beam does not reach the other part of the chamber, for example,
labeled proteins floating around in solution.
This article is not meant for you if you want to learn the science behind the ion - exchanged, cross-mutaed,
isotopically labeled protein tracers - blah blah blah.
A miniscule amount of protein hidden in 200 calories worth of dried fruits and nuts (you know what I'm talking about, and anyone
who labels this a protein bar is totally kidding herself.
Arla Foods Ingredients has developed a unique new clean -
label protein solution that tackles the long - standing problem of watery low - fat cottage cheese.
A microfluidic device captures cells, lyses them, and separates their contents, allowing naturally fluorescent and
labeled proteins in a single cell to be counted.
Rice University scientists have learned to spy on cells with a divide - and - conquer strategy to
label proteins.
Using confocal microscopy and fluorescently
labeled proteins, the scientists discovered that BAG3 appeared to be sequestering VP40 in the cell's cytoplasm away from the plasma membrane where the viral particles would need to go in order to bud off and spread to infect other cells.
The method is based on a technology called single - molecule array digital ELISA that can identify individual antibody -
labeled proteins.
BONCAT uses synthetic amino acids to
label protein - making cells.
Another well - known invention is a process called bioorthogonal chemical reactions, which can be used to
label proteins, sugars, and other molecules in living cells and animals without damaging the cells.
They were able to do this by examining the drug and without having to
label the protein, as is required in some other methods.
