The U-937 cell line was derived by Sundstrom and Nilsson in 1974 from malignant cells obtained from the pleural effusion of a patient with histiocytic lymphoma.
Studies since 1979 have shown that U-937 cells can be induced to terminal monocytic differentiation by supernatants from human mixed lymphocyte cultures,
phorbol esters, vitamin D3, gamma interferon, tumor necrosis factor (TNF) and, retinoic acid. The cells express the Fas antigen, and are sensitive to TNF and anti-Fas antibodies. The Transfection Reagent: Transfection of suspension cells, such as U-937 Cells, has always been challenging, both technically and financially. The most common systems currently used for relatively efficient molecular delivery to these cells are expensive electroporation instruments. U-937 Cell Avalanche™ Transfection Reagent is a new, proprietary solution specifically designed for transfection on U-937 Cells. The proprietary formulation of lipids and polymers ensures the highest possible transfection efficiencies and viabilities for U-937 Cells. No other transfection reagents can match the efficiency, convenience, and gentleness of U-937 Cell Avalanche™ Transfection Reagent for transfection on U-937 Cells.

U-937 Cell Avalanche™ Transfection Reagent (human lymphoma cell) can also be used on the following cells with high transfection efficiencies.
293 Cell
293T/17 Cell
NIH/3T3 Cell
3T3-L1 Cell
BALB/3T3 clone A31
3T3-Swiss albino Cell
CT26.WT Cell
NCTC Clone 929 Cell Recommended protocols for these cells will be provided with the reagent. The protocols usually provide satisfactory transfection efficiency with invisible cytotoxicity. However, optimization may be needed for certain type of cells. Optimizations may include: the amount of DNA and this transfection reagent; cell density; transfection reagent/DNA ratio, or incubation time for the mixture of transfection reagent/DNA etc. For best transfection result, we recommend using the respective cell type/cell line specific Avalanche transfection reagents. Those reagents have been optimized on both recipes and protocols, and have been proved to have the best transfection results for the respective cell lines or primary cells. You can easily find the respective Avalanche transfection reagents specific for your cells by using the filters of our product list. |
