U-2 OS cell Avalanche® Transfection Reagent (human osteosarcoma cell)
U-2 OS cell Avalanche® Transfection Reagent is a new class of unique chemical formulations specifically formulated and optimized for transfecting U-2 OS cells. The proprietary formulation of lipids and polymers ensures the highest possible transfection efficiencies and viabilities for U-2 OS cells. For details of the developing process of this reagent, please go to: How did EZ Biosystems develop Avalanche® Cell type/cell line specific transfection reagent series?
Karyotype: Cell line U-2 OS is chromosomally highly altered, with chromosome counts in the hypertriploid range.
J. Ponten and E. Saksela derived this line (originally 2T) in 1964 from a moderately differentiated sarcoma of the tibia of a 15 year old girl.
Features of The Transfection Reagent:
Broad spectrum for the transfection of large plasmid, mRNA, siRNA, and/or other type of nucleic acids, which is best for co-transfection of different type and/or size of nucleic acids.
Specifically optimized to deliver nucleic acids into U-2 OS cells
Highest efficiency to ensure experimental success
Lowest Cellular Toxicity-maintain cell density and reduce experimental biases
0.5 ml is able to transfect about 1000 wells of 24-well plate
Animal-free
Compatible with serum
Suitable for Reverse Transfection
Economical: High efficiency means less amount of nucleic acid & reagent is needed
Developed and manufactured by EZ Biosystems
Data
FIG. 1. High throughput test of transfection efficiency (determined as RLU/mg) on U-2 OS cells after transfection of luciferase reporter gene by using our 172 proprietary transfection formulas and several most popular commercial transfection reagents. The yellow box showed the results of 4 commercial transfection reagents. The red lines marked our candidate formulas with the highest transfection efficiency for U-2 OS cells. This test result was confirmed with repeat experiments. The one that showed the optimal balance of potent & low cytotoxicity among those candidate formulas after flow cytometry analysis on the percentage of 7AAD positive cells was later named as this U-2 OS Cell Avalanche Transfection Reagent.
FIG. 2. U-2 OS cells were transfected with GFP vector (pEGFP-N3) by using U-2 OS Avalanche® Transfection Reagent. The cells were visualized by Nikon Eclipse Fluorescence microscope 24 hours post transfection.
For Other Cells
U-2 OS cell Avalanche® Transfection Reagent (human osteosarcoma cell) can also be used on the following cells with high transfection efficiencies.
Saos-2 Cell
Vero Cell
293 Cell
786-O Cell
DU 145 Cell
22Rv1 Cell
VCaP Cell
PC-3 Cell
AR42J 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.
