Place the tubes in the ice-water bath. 9 Analyse the samples within 8 hours. This method was developed for blood samples with a normal white count. Ion exchange chromatography following ammonium sulphate precipitation. The CR3 receptor is expressed as a surface molecule by circulating monocytes and granulocytes and also by dendritic reticulum cells in sections of lympoid tissue.
Expression is increased on activated granulocytes.
We recommend that each laboratory determine an optimum working titre for use in its particular application. However repeated warming to room temperature and re-cooling may result in a loss of activity and hence effective working titre. After thawing they should then be used as a stock solution for up to 60 days. Dilute working solutions are best prepared on the day of use. For research use only.
