Cellular lysates were fractionated by gel-permeation size-exclusion chromatography on Sepharose 6B (Sigma-Aldrich, fractionation range for globular proteins 1 × 10 ÷ 4 × 10) column of 90 cm high and 1 cm of diameter.
Chromatographic separation of glycans may be performed by adsorption chromatography, which is mostly done in the HPLC mode, by gel permeation chromatography (size-exclusion chromatography [ 148]), or by (capillary) gas chromatography [ 85, 149].
In this paper, organic solvent nanofiltration (OSN) membranes with thin film composite (TFC) structures were characterised in terms of the permeation pathway ('pore') size and separation layer morphology.
The MR has negative effects on the surface etching, the improvement of hydrophilicity, sizing adhesion and size permeation uniformity of raw cotton yarns by APPJ.
Observation of the cross sections shows that the roving with the lowest MR has a more uniform layer of size permeation than that for higher MR samples, while the side facing the plasma jet has a thicker size impregnation than the other side.
Second, increase in effective pore radius in the junction, caused by differences in claudins and other proteins that create the sieving effect, will increase paracellular permeation over certain size ranges of molecules [16], [37].
NPP are generally described as transporting a broad range of substrates, with a preference for anions and electroneutral compounds over cations, and with the rate of permeation influenced by size and hydrophobicity of the solute in a number of cases [17].
Although FB containing OBZ had larger oil droplet size, permeation of OBZ from FB still significantly increased comparing to FA.
Using an in-vitro model designed to mimic the transport-permissive brain microvasculature, we demonstrate size-dependent permeation properties with respect to core particle size and PEG chain length.
The permeation studies revealed the size dependent diffusion rate of the model drugs through the NFC films.
