For instance, Bayer in collaboration with Assistance Publique - Hopitaux de Paris is studying combination of rivaroxaban and low
molecular weight heparin for neoplasm and venous thromboembolism, which is in phase 3.
Egg yolk allergens: Egg yolk contained two major allergenic proteins having approximately
molecular weight of 70KDa and 42KDa.
The [M.sub.n] and [M.sub.w] of the obtained polyesters were calculated from the
molecular weight distribution measured using the aforementioned procedure.
Unless some type of mechanical performance test is performed by the processor, changes in
molecular weight will go unnoticed until something fails after the product has moved farther down the supply chain.
Although the animal data,
molecular weight (about 868), and elimination half-life (about 26 hours) suggest embryo-fetal risk, the high plasma protein binding (99.9%) should limit the amount crossing the placenta.
Specifically, the relatively high
molecular weight and long polymer chain length result in entanglement, and the lack of covalent intermolecular bonds facilitates polymer chain mobility.
In the cholesterol-linoleic acid emulsion model, the 2% low
molecular weight chitosan group exhibited the highest retention rate of linoleic acid at 64.2%, compared with other treatments, in which retention rates ranged from 32.1% for the 2% high
molecular weight group to 9.3% for the control group.
Gel permeation chromatography (GPC) or size exclusion chromatography (SEC), is a powerful separation technique particularly applicable for calculating the
molecular weight of high-molecular-mass species such as polymers.
This permits the determination of accurate
molecular weight distributions without a relevant standard, an important benefit for new or significantly modified polymers where appropriate reference materials may not be available.
"Considering the use of atom transfer radical polymerization, it is possible to achieve very high
molecular weight uniform grades in this study.
The web features a solid matrix including an ultrahigh
molecular weight polyolefin component and a friable, highly dispersing, precipitated silica component.
