The objective of this study was to find a simple method to preserve cells for subsequent flow cytometry (FACS) analysis. We determined that fixation in 1% paraformaldehyde-0.85% saline solution did not significantly alter the Coulter volume, light scatter of fluorescence

Present methods for assay of platelet aggregating agents use freshly prepared platelets. Much time is spent in daily preparation of platelets and standardization presents problems. The preparation of fixed washed platelets (FWP) and their use in two bioassays are described

Carbonylation reactions represent useful tools for organic synthesis. However, the necessity to use gaseous carbon monoxide is a disadvantage for most organic chemists. To solve this problem, novel protocols have been developed for conducting palladium-catalyzed reductive carbonylations of aryl bromides

Angiogenic, that is, newly formed, blood vessels play an important role in tumor growth and metastasis and are a potential target for tumor treatment. In previous studies, the alpha(v)beta(3) integrin, which is strongly expressed in angiogenic vessels, has been used
