Equal amounts of protein are used for each sample under comparison so that any differences in relative peptide/protein amount measured by mass spectrometry reflect differences between samples, not starting protein amounts.
The particle-size distribution (PSD) of a powder, granular material, or particles dispersed in fluid is a list of values or a mathematical function that defines the relative amount, typically by mass, of particles present according to size.
The hydrogen in cluster stars is thought to amount to 70 75 percent by mass, helium 25 30 percent, and the heavier elements 0.01 0.1 percent.
For production of each type of fiber reinforced composite (FRC), fibers having length of 50 mm are added in concrete by an amount of 5% (by mass of cement).
Both carbon fiber and carbon black (used with silica fume in the amount of 15% by mass of cement) increase the DC conductivity and the EMI shielding effectiveness of cement, but carbon fiber is more effective than carbon black.
Currently, batteries store less than 1/60th as much energy as an equivalent amount of gasoline by mass and 1/30th by volume.
The identification of subpicomolar amounts of protein by mass spectrometry (MS) coupled with two-dimensional methods to separate complex protein mixtures is fueling the field of proteomics, and making feasible the notion of cataloging and comparing all of the expressed proteins in a biological sample.
This technique is used to quantify relative protein amounts as measured by mass spectrometry in extracts from cells grown in unlabeled (light) medium and cells grown in (heavy) medium containing non-radioactively-labeled amino acids.
Furthermore, the culture medium of neonatal PT slices in Fig. 3F and S2 in Supporting Information was collected, and secreted TSHβ amounts were measured by mass spectrometry.
Yes, the mass of the black hole increases by the amount of mass that was captured.
Using this method, the amount of mass loss by erosion was measured on imprints taken from the site.
