NPS was then separated into four fractions with different average relative molecular mass by means of solvent extraction. 采用溶剂萃取法将NPS按平均相对分子质量的不同分离为若干组分,采用元素分析、1H-NMR及13C-NMR表征各组分的分子结构,并测定了它们的界面张力、临界胶束浓度(CMC)和在孤岛地层砂上的吸附量...
1)viscosity-average relative molecular mass黏均相对分子质量 1.The effects of solid content of latex,reaction temperature,the amount of phenylhydrazine and pepegal O on the viscosity-average relative molecular mass(η) of LNR were investigated,and the optimization of these influence factors was conduct...
ethanol fractionation urea dissolved fusion protein separation, 60mmol L hydrolysis / hydrochloric acid fusion protein, DEAE-52 column chromatography → HPLC isolated Pro-Pro-h [Gly 2 ] GLP-2 (1-35), electrospray ionization mass spectrometry measured obtaining the relative molecular mass of 3948Da....
Further, targeting drug resistance mechanisms of sorafenib may lead to the development of novel strategies to improve the efficacy of sorafenib in HCC. Mass spectrometry-based proteomic technology is currently used to study and compare the proteomes of in vitro and in vivo models of cancer as ...
and that cells outgrowing from stationary phase will always experience a period of active width increase due to optimal resource allocation to volumetric growth. This model focuses on global resource constraints rather than specific molecular machineries, and therefore is broadly applicable to other microb...
and isotope ratio mass spectrometer (IRMS; Finnegan Delta Plus XP, Thermo Sci.). EA-IRMS run sequences were setup with pre-weighed pugel and acetanilide standards, and the pelleted samples. Any drift in the isotopic signal during sample runs were adjusted based on the signal of internal ...
To identify potential molecular mechanisms we utilized transcriptional analysis of tumor and unaffected adjacent tissue. Results AOM 1–Strain by exercise interactions We investigated the impact of genetic background, exercise, and their interaction on tumor number and size (Fig. 1). As a result of...
(rai), calculated as the number of spectral counts (spc) divided by molecular mass (mr) of protein, in exponential phase cell-free extracts. differences in protein expression levels between exponential and stationary phase cell-free extracts labeled with isobaric tags for relative and absolute ...
While the exact droplet composition depends strongly on many factors, the typical mass or volume proportion of non-water content in a droplet is around ϕ0 = 1 to 10% [48, 55, 57, 77, 78]. A hypothetically completely dried-out droplet devoid of water would thus have a radius of:...
The mass spectra deconvolution tool was used to automate calculation of the molecular mass of components in the mixture. Charge deconvolution was performed over a range 5–30 kDa with a 10% abundance cutoff. Extracted ion chromatograms were generated for the subunits of BfrB (18,552 Da) and ...
