For this purpose, a set of hydrophobically-modified pullulans (HMCMPs) of moderate molar mass and differing in hydrophobic modification ratio, charge ratio and the nature of the hydrophobic chains introduced, were prepared.
The mechanical and physical properties of GG-HA hydrogels were controlled by changing the molecular weight, the degree of modification, and the ratio of polymer components.
A decrease of the latent heat of melting of the gels with increasing melting pressure (decreasing of the melting temperature) probably indicated a modification in the ratio of frozenable water in these gels under pressure.
In fact, whether there is kinetic or external heat transfer control is mainly determined by the two dimensionless groups 3Nukl,∞ /2Aρc,o¯¯¯Cr2o (a modification of the ratio of the characteristic times for chemical reaction and a coal particle to heat up) and RT∞/Ev.
This will enable accurate characterisation of the vaccine for commercial licensing and further optimisation by modification of the ratio of eukaryotic and prokaryotic expression to improve vaccine immunogenicity.
The human endocrine pancreatic tumor cell line BON (a kind gift from Prof J.C. Thompson, Galveston, TX) was cultured in DMEM with Glutamax-I and F12 Nutrient Mixture (Kaighn's modification) at a ratio of 1∶1, supplemented with 10% fetal bovine serum (FBS), 1 mM sodium puruvate and 1% penicillin/streptomycin (PEST).
Thus, in addition to modification of the ratio of cell types, there is differential activation of the co-regulated innate and adaptive gene functions.
To confirm the distribution profiles of histone modifications, we calculated the ratio of histone modifications (H3K4me3 and H3K9ac) to pan-H3.
The relative ionization efficiencies of the modified and unmodified peptides can then be calculated from the modification-induced change in the ratio of relative abundances of the ion of the peptide of interest over that of the internal standard peptide.
At single-stage modification under the same conditions (temperature 250 °C, the degree of modification is 20%%, the ratio of polymer/DMC is 5.5), the sample loses uniformity.
