A wide range of admixtures with different molecular weight and constant structure was prepared.
It is biologically similar to infliximab in molecular weight and constant region sequence, except that it is fully humanized and not chimeric [ 29].
The molecular weight kept almost constant at low SiO2 content (<8 wt%) but decreased at higher SiO2 content.
A compensation of these quantities was shown, i.e. their values were found for which the ratio of weight- to number-average molecular weight, Mw/Mn, was constant.
Using 21 formulations based on low molecular weight chitosans with constant charge density and a number-average degree of polymerization (DPn) in the range of 21 88 (Mw 4.7 33 kDa), we studied the relationship between the chain length and the formulation properties, cellular uptake of polyplexes and gene transfer efficacy.
The nanoworms may assemble with a scFv core; however, these particles have a lower absolute molecular weight and relatively constant radius of gyration.
Concomitant increases in total Zn concentration and Zn bound to MTs were observed in the liver, whereas Zn concentration bound to high molecular weight proteins remained constant.
Sulfadiazine (purity > 99%), sulfamerazine (purity > 99%), and sulfamethoxazole (purity > 99%) were all purchased from Sigma-Aldrich (USA); their physical and chemical properties (molecular formula, structural formula, molecular weight, ionization equilibrium constant pKa, etc).
An increase in total Zn concentration in the liver was followed by an increase in Zn concentration in the cytosol and Zn bound to cytosolic MTs (r = 0.8, p < 0.001), while Zn bound to high molecular weight proteins remained constant.
Crowding level is used instead of volume fraction percent (v/v), since it requires no assumptions about polymer size in terms of spatial dimensions, which are unknown and which vary in crowded solutions depending on structuring, whereas size mass (molecular weight (MW)) remains constant.
