Cell Line Information:
Designations: NCI-H441
Organism: Homo sapiens (human)
Tissue: lung, papillary adenocarcinoma
Gender: male
Morphology: epithelial
Growth properties: adherent
Depositors: A.F. Gazdar; J.D. Minna
The NCI-H441 cell line was derived by A.F. Gazdar, M. Brower and D. Carney and associates in 1982 from the pericardial fluid of a patient with papillary adenocarcinoma of the lung. The cell line expresses mRNA and protein of the major surfactant apoprotein (SP-A). Electron microscopy shows multilamellar bodies and cytoplasmic structures resembling clara cell granules. The line has been used as a transfection host for expression of pulmonary surfactant protein (SP-B).
The Transfection Reagent:
NCI-H441 Cell Avalanche™ Transfection Reagent is a new, proprietary solution specifically designed for transfection on NCI-H441 Cells. The proprietary formulation of lipids and polymers ensures the highest possible transfection efficiencies and viabilities for NCI-H441 Cells. No other transfection reagents can match the efficiency, convenience, and gentleness of NCI-H441 Cell Avalanche™ Transfection Reagent for transfection on NCI-H441 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?
Features:
- Specifically optimized to deliver nucleic acids into NCI-H441 Cells
- Highest efficiency to ensure experimental success

| FIG. 1. High throughput test of transfection efficiency (determined as RLU/mg) on A549 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 A549 cells. This test result was confirmed with repeat experiments. The candidate formulas were also tested on NCI-H441 cells by tranfecting GFP expression plasmid, and got the same high transfection efficiency after flow cytometry analysis. The one that showed the optimal balance of potent & low cytotoxicity (percentage of 7AAD positive cells) among those candidate formulas was later named as NCI-H441 Cell Avalanche Transfection Reagent. |

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. |
