The phrase "molecular weight difference" is correct and usable in written English.
It can be used to refer to the difference in weight between molecules of different substances. For example: "By calculating the molecular weight difference between oxygen and nitrogen, scientists were able to determine the composition of the atmosphere."
Despite the equilibration of neutral substitution rates, gene pairs in the two groups differed dramatically, on average, in molecular weight difference (0.04 recent vs. 0.13 single) and isoelectric point difference (0.8 recent vs. 0.12 single).
The viscoelastic properties of the branched polyethylenes were very complicated due to the combined effect of the molecular weight difference and the degree of chain branching as well as the branching structure.
A robust high-throughput single-nucleotide polymorphism (SNP) genotyping method is reported, which applies allele-specific extension to achieve allelic discrimination and uses matrix-assisted laser desorption/ionization time-of-flight mass spectrometry to measure the natural molecular weight difference of oligonucleotides for determination of the base in a single-nucleotide polymorphic location.
This augmentation cannot be explained by the molecular weight difference.
An explanation for this difference might be the molecular weight difference, i.e. the bulkier and charged NOX-C89 might have a slower uptake kinetic into the relevant compartment.
Importantly, this molecular weight difference can only be used as surrogate marker.
Molecular weight differences of the polymer samples produce little variation in conductivity of the grafted samples, whereas the above chemical aspects, heating rate and temperature influence the conductor mechanism.
Minor molecular weight differences are due to the His-tag.
Due to the molecular weight differences in the amplified fragments after digestion, it is possible to clearly distinguish the characteristic bands of each subtype by visual analysis of agarose gels.
Special attention is given to the effects of polymer molecular weight, pressure, differences in segment size and differences in segment interaction energy.
This might be due to the difference between the molecular weight of different crude and purified durian seed gums (A-D).
