WebJan 1, 1993 · It is applicable to soluble as well as to cellular antigens and allows comparison with polyethylene glycol (PEG)-induced fusions starting from the same parental cell suspensions. The accumulated data confirm that electrofusion results in higher hybridoma yield as compared to PEG-induced fusion. WebPolyethylene glycol (PEG) induced cell fusion has become a standard technique particularly in the hybridoma technology. PEG induced fusions are easy to perform and a high number of cells can be fused in a shorter time. However, the technique suffers from low fusion efficiency and the many unwanted fusion products are created. theappkit

Microfluidic control of cell pairing and fusion Nature Methods

There are four methods that cell biologists and biophysicists use to fuse cells. These four ways include electrical cell fusion, polyethylene glycol cell fusion, and sendai virus induced cell fusion and a newly developed method termed optically controlled thermoplasmonics. Electrical cell fusion is an essential step in some of the most innovative metho… WebPolyethylene glycol (PEG) and electrofusion were applied together in a simple and highly efficient cell fusion method. PEG (8000 M(r)) was used to bring human erythrocytes into contact, and a single 4.4 kV/cm, 80 microseconds duration pulse was applied to cell suspensions.

WebMar 9, 2024 · The paired cells are then treated with fusogenic PEG for cell fusion. Compared with traditional protocols, cell fusion using this approach is well defined with better control, which leads to an improved yield of heterotypic binucleated hybrids. WebPolyethylene glycol (PEG)-mediated cell fusion is a simple and efficient technique used widely for the production of somatic cell hybrids and for nuclear transfer in mammalian cloning. We describe a basic protocol of PEG-mediated cell fusion for the production of somatic cell hybrids.

WebPEG is capable of fusing a wide variety of cells, including interspecific and interkingdom cell types. PEG exhibits a very low degree of cytotoxicity; it is only toxic at high concentrations (greater than 50%) and prolonged incubation (minutes for most cell lines). WebJun 22, 2024 · We found that PEG-6000–induced cell fusion correlated with increased type I IFN gene expression in both HepG2 liver epithelial cells ( Fig. 2 F and G and SI Appendix, Table S1) and primary human mesenchymal stem cells (hMSCs) ( SI Appendix, Fig. S1 F and G and Table S1 ).

WebSep 20, 2011 · Cell fusion induced by polyethylene glycol (PEG) is an efficient but poorly controlled procedure for obtaining somatic cell hybrids used in gene mapping, monoclonal antibody production, and tumour immunotherapy.
