Expression of Nucleocapsid Protein Gene of Porcine Reproductive and Respiratory Syndrome Virus in Soluble Form and Development of an Indirect ELISA for the Detection of Viral Antibodies with the Expression Product
The ascorbic acid retention was 51.8%～62.6%and the retention of firmness was 70.1%～78.6%after storage for 8months. While the retention of total soluble solids was 87.2%～88.8%,the titratable acidity retention was 102.9%～113.1%.
The result showed that the fruit firmness,titratable acids and total soluble solids of 1 MCP treatment were reduced from previous 9.2 kg/cm 2,6.709 g/L and 14.0% to 8.6 kg/cm 2,5.194 g/L and 13.5% respectively,which were lower than those of the control.
Under low concentration stress Hg2+≤2.5μmol/L, Cd2+≤10μmol/L and Hg2++Cd2+≤1.25μmol/L Hg2++5μmol/L Cd2+, the contents of dissoluble protein and chlorophyll increased slightly; and then decreased continuously with increase of the stress with negative correlation.
Each group was divided into 6 subgroups, among which, 5 different concentrations of dissoluble mixed crystalline liquid(1,0.5,0.02,0.01,0.005 mg/L) were divided into 5 subgroups,1 subgroup without dissoluble mixed crystalline liquid.
The inclusion complex formation of tanshinone IIA (Tan IIA) with hydroxypropyl-β-cyclodextrin (HPCD) was studied by using phase solubility method, and the formation constant for tanshinone IIA-HPCD-dextrin was determined.
The result of the dissolution experiment showed that solubility of BCVL in organic solvent was improved compared with crystal violet lactone (CVL).
The results indicate that the solubility of cinnabar could be increased significantly in the presence of Na2S/S0, and strong acidic pH, respectively.
The maximal solubility for Fe substitution seemed to be reached at x = 0.65.
It is found that because of the small solubility of Fe2O3 in La2Mo2O9 (>amp;lt;5%), Fe doping cannot suppress the phase transition that occurred around 570°C, but 2.5% K doping at La site at the same time (e.g.
In this cultivar the ratio of flavonols reached 50% of total soluble phenol content.
The amount of HBsAg in leaves, microtubers, and tubers of transgenic potatoes growing in vitro and in vivo was 0.005-0.035% of the total soluble protein.
The antigen amount in plants carrying the HBsAg gene under a single 35S promoter was 0.0001-0.001 of the total soluble protein whereas the use of a dual 35S promoter increased the antigen synthesis to 0.002-0.05% of the protein.
In the F1 plants, the antigen expression varied in different lines comprising 0.001 to 0.03% of the total soluble protein, which corresponded to the antigen amount in the F0 plants.
Both enzyme activities gradually reduced as the temperature and the total soluble protein decreased.
Anodic polarization behavior of gold, silver, copper, nickel and iron in potentiostatic condition has been examined in an alkaline aqueous thiourea solution, where gold is hardly dissoluble normally.
The reason for Ag, Cu hardly being dissoluble is that the black layers of Ag2S and Cu1.92S form on the surface of Ag and Cu.
Moreover, because of high evaporation, the salts that are in the groundwater is congregated on the earth's surface, the dissoluble salts (Cl-, SO42-) turn into lake, which accounts for the reason for the high correlation between Cl- and SO42-.
Red precipitate in a sinter is dissoluble to strong acid.
Usually, PbS was precipitated via the reaction between dissoluble lead salt and H2S gas in aqueous media.
