Determination of infectious retrovirus concentration from colony-forming assay with quantitative analysis.
The colony formation assay is the most commonly used titration method for defining the concentration of replication-incompetent murine leukemia virus-derived retroviral vectors. However, titer varies with target cell type and number, transduction time, and concentration of polycation (e.g., Polybrene). Moreover, because most of the viruses cannot encounter target cells due to Brownian motion, t...
متن کاملA Quantitative Assay for Insulin-expressing Colony-forming Progenitors
The field of pancreatic stem and progenitor cell biology has been hampered by a lack of in vitro functional and quantitative assays that allow for the analysis of the single cell. Analyses of single progenitors are of critical importance because they provide definitive ways to unequivocally demonstrate the lineage potential of individual progenitors. Although methods have been devised to gener...
متن کاملMeasuring Survival of Adherent Cells with the Colony-Forming Assay.
Measuring cell death with colorimetric or fluorimetric dyes such as trypan blue and propidium iodide (PI) can provide an accurate measure of the number of dead cells in a population at a specific time; however, these assays cannot be used to distinguish cells that are dying or marked for future death. In many cases it is essential to measure the proliferative capacity of treated cells to provid...
متن کاملDetermination of Protein Concentration Using Bradford Microplate Protein Quantification Assay
Background: Bradford protein assay is popular due to its ease of performance and relative sensitivity. Many researchers and laboratories in Iran use standard assay of Bradford by cuvette. No commercial kit was available for Bradford microplate assay in Iran. Meanwhile, imported Bradford commercial kits are very expensive and have a long delivery time in Iran. Till now no study or document on Br...
متن کاملAssay of Colony Forming Units in Culture (cfu-c)
The colony forming units in culture (cfu-c) in bone marrowcells, which were suppressed by immunosuppressive factor obtained from the serum of sarcoma 180 tumor bearing mouse, was restored to normal level by the addition of FR-900490in vitro. Furthermore, in mitomycin C (MMC)-treated mice the subsequent administration of FR-900490caused a significant increase of cfu-c in bone marrow cells depres...
