744 INSIGHTS | The Journal of Experimental Medicine In this issue, two independent groups show that the transcription factor ZBTB20 is required for the maintenance of long-lived plasma cells following immunization with the commonly used adjuvant, alum. Intriguingly, one group found that ZBTB20 was dispensable for plasma cell survival when they used adjuvants that activate Toll-like receptors (T...

The clonogenic cell survival assay determines the ability of a cell to proliferate indefinitely, thereby retaining its reproductive ability to form a large colony or a clone. This cell is then said to be clonogenic. A cell survival curve is therefore defined as a relationship between the dose of the agent used to produce an insult and the fraction of cells retaining their ability to reproduce. ...

abstract background: gastric cancer is a life threatening disease. recent studies have shown that rosa damascene possesses noticeable biological effects on the human body. this study, investigates the anticancer effect of rosa damascena on gastric cancer cell line mkn45. methods: microscopic studies and mtt assay were used to examine morphological alteration, and cell survival of the cancer cel...
