The gels can be used to extract water and low molecular weight solutes from macromolecular solutions.
In this study, we have systematically optimized the various process parameters such as flow rate, applied voltage, tip-target distance, and the solution parameters (viscosity, molecular weight, and solution conductivity) to obtain defect-free random fibers of PLGA, PLGA-undoped PHT, PLGA-doped PHT, and aligned PLGA-doped PHT nanofibers.
A high molecular weight polymer solution in an organic solvent containing dispersed water-soluble salt particles is precipitated into an excess of non-solvent.
A wide range of fiber diameters (267 nm to 2.8 μm) and morphologies (beaded, round, branched and ribbon) could be achieved by PAAm molecular weight and solution properties.
Subsequently, NG were isolated by mixing platelet-depleted serum from the same blood donor, diluted 1 1.3 with a high molecular weight dextran solution (Macrodex; Fresenius, Bad Homburg, Germany) containing 0.01 M EDTA.
The pellet was mixed with platelet-depleted serum from the same blood donor and diluted by 1 1.3 with a high molecular weight dextran solution (Macrodex; Fresenius, Bad Homburg, Germany) containing 0.01 M EDTA.
AChE crystal structure [ 65] and our estimation of its molecular weight in solution (Additional file 6) suggest the formation of a dimer with the identified interaction hotspot in each catalytic subunit facing the opposite sides of the complex (Additional file 5a).
We have shown that lubricin is able to reduce the viscosity of a high molecular weight HA solution when both components are present at physiological concentrations, potentially by binding and shrinking the hydrodynamic domains of HA molecules, enabling them to flow more easily.
Prestained molecular weight marker solution (broad range, Bio-Rad) contained myosin (192.8 kDa), β-galactosidase (117.9 kDa), bovine serum albumin (99.3 kDa), ovalbumin (54.1 kDa), carbonic anhydrase (37.8 kDa), soybean trypsin inhibitor (29.5 kDa), lysozyme (20.2 kDa) and aprotinin (7.4 kDa).
Where, do: density of pure solvent ds: density of solution m : molarity of solution M : molecular weight of solute β o : adiabatic compressibility of pure solvent β s : adiabatic compressibility of solution.
