A general procedure for HA is as follows, a serial dilution of virus is prepared across the rows in a U or V- bottom shaped 96-well microtiter plate. The most concentrated sample in the first well is often diluted to be 1/5x of the stock, and subsequent wells are typically two-fold dilutions (1/10, 1/20, 1/40, etc.).The final well serves as a negative control with no virus. Each row of the plate typically has a different virus and the same pattern of dilutions. After serial dilutions, a standardi… WebMar 24, 2024 · Even 20 years ago, an important negative prognostic factor for AML was known to be a high white blood cell count. 1 In retrospect, it seems likely that a large fraction of these patients whose poor prognosis was derived from hyperleukocytosis harbored activating mutations in the FLT3 gene.
