Question

Static light scattering indicates this quantity for biomacromolecules. After trypsinization, proteins are sequenced by measuring this quantity for their trypsinized peptides to four decimal place precision. This property of a protein is estimated from a Coomassie-stained ladder with bands at 25, (20[1]0[1])37, (20[1])50, and 150 of this quantity’s (20[1])standard units. (20[1]0[1])In proteomics, this quantity is measured twice in tandem: once after MALDI (20[1])(“MAUL-dee”) or ESI (20[2])(“E-S-I”), and then again on (*) fragments (10[1])of the molecular ion. (10[1])In SDS-PAGE (10[1])(“S-D-S page”), proteins with higher (10[1])values of this quantity migrate slower (10[2])through (10[1])a gel. (10[3]0[1])Molecules are identified (0[1])by measuring the ratio of this quantity to charge (0[1])in a type of spectrometry (10[3])named for (10[1])it. (10[2])For 10 points, name this quantity that is measured (10[1])for macromolecules in daltons or grams. (10[5])■END■ (10[5]0[1])

ANSWER: mass [or molar mass; or molecular weight; accept mass-to-charge ratio or m-over-z; prompt on length or size]
