Nettet25. mai 2016 · The way this is done is by limiting dilution assay (LDA), which is performed as follows: Put equal numbers of cells in all wells of a 96 well plate (8x12) Take your virus of unknown concentration and perform serial dilutions (e.g. starting from 10e-2 make serial 5-fold dilutions to span all 12 columns of the plate) NettetLimiting dilution assays are widely used in infectious disease research. These assays are crucial for current human immunodeﬁciency virus (HIV)-1 cure research in particular. In this study, we offer new tools to help investigators design and analyze dilution assays based on their speciﬁc research needs. Limiting dilution assays

NettetA typical concentration used for limiting dilution is 0.5-1 cells per 100 μl aliquot because it maximizes the probability of obtaining a single cell per well while minimizing the probability of depositing multiple cells per well. At this concentration, one can expect about a third of the wells to contain a single cell and most wells to be empty. Nettet5. sep. 2024 · 4. Create secondary serial dilutions of your target using smaller steps and more replicates. Following this example, you would start with 100 copies per reaction.
