To neutralize the low pH, 100 μl of neutralization buffer (1 mol/L Tris-HCl, pH 7.5) was added for each 100 μl of eluate. Western blotting was used to assess protein precipitation. Monocyte adhesion assay Human endothelial cells were cultured on coverslips in 24-well plates. Upon...
For preparation of the novel porphyrin complexes of the invention by the methods above suitable conditions are 37° C., preferably in the dark. The concentration of porphyrin, metal and ligand (if used), do not appear to be critical, but a convenient concentration is about 0.02M each. Under...
Example 19 describes the preparation of aluminum phosphate sol in the presence of an HCl catalyst. A solution containing aluminum s-butoxide (0.082 gm, 0.37 mmol), phenyltrimethxoxysilane (0.092 gm, 0.46 mmol), ethylphosphate ((0.068 gm, (0.37 mmol) and methoxyethanol (0.4 gm) is prepared ...
5.14a-dW Preparation of Pasteur filter pipet. The container (conical vial or centrifuge tube) holding the crystal-mother liquor mixture is cooled in an ice-water bath. A Pasteur filter pipet is used to slightly stir the mixture. The air is then slowly pushed from the pipet as the tip of...
A “holding time” is the elapsed amount of time from the point of collection to the moment of preparation or analysis. Note that this is not the date/time of receipt at the lab! If samples are analyzed beyond an analytical holding time, the data will be qualified on the analytical repor...
