In this paper, the molecular weight of PET residue measured by gel permeation chromatography (GPC) was used to track the progress of PET depolymerization. The results showed that the molecular weight of the residue after depolymerization under 180°Cdecreases as reaction time increases, however when...
By combining molecular weight information, obtained without the need of any SEC calibration curves, with intrinsic viscosity measurements, on several broad molecular weight PET samples, the Mark–Houwink coefficients for the five PET–solvent systems mentioned above have been determined. The...
Photoinduced graft polymerization of N-vinylimidazole (VI) and graft copolymerization of N-vinylimidazole with acrylic acid (AA) onto track-etched polyethylene terephthalate membranes (PET TeMs) with a pore diameter of 450 卤 15 nm have ... M Anastassiya,AL Kozlovskiy,Z Maxim - 《Materials Resea...

This chapter focuses on the application of PET for the evaluation of the pharmacokinetics (PK) of small molecular weight drugs in human subjects. PET is recommended as a unique tool for comparison of aerosol drug delivery devices that deliver drugs to pulmonary tissue via oral inhalation or nasal...

High resolution and high mass accuracy provided by mass spectrometry (MS)-based untargeted metabolomics would enable the rapid detection and wide coverage of the low-molecular-weight peptidome. However, translating unknown masses (<1 500 Da) into putative peptides is often limited due to the ...
ClpA pore-2 mutations were introduced using round-the-horn mutagenesis with T4 polynucleotide kinase and Q5 high-fidelity polymerase (New England Biolabs) into pET9a-M169TClpA, the plasmid used to express ClpA (gift from J. Flanagan, Hershey Medical Center). The primers used for mutagenesis ar...
The pET28a vectors containing the NvfI gene were prepared previously12. The plasmid was transformed into Escherichia coli RosettaTM 2(DE3) pLysS and used for the expression of NvfI and its variants. The cells harboring the plasmids were cultured at 37 °C to an OD600 of 0.6 in Luria-Ber...
Breast cancer, the most frequent female malignancy, is often curable when detected at an early stage. The treatment of metastatic breast cancer is more challenging and may be unresponsive to conventional therapy. Immunotherapy is crucial for treating met
