Goat anti Human properdin

The lyophilized antiserum is shipped at ambient temperature and may be stored at +4 °C; prolonged storage at or below -20 °C. Reconstitute the lyophilized antiserum by adding 1 ml sterile distilled water. Dilutions may be prepared by adding phosphate buffered saline (PBS, pH 7.2). Repeated thawing and freezing should be avoided. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance of the antiserum. Diluted antiserum should be stored at +4 °C, not refrozen, and preferably used the same day. Lyophilized at +4 °C--at least 10 years. Reconstituted at or below -20 °C--3-5 years. Reconstituted at +4 °C--7 days
