EZT-COLO-1 Protocol.
Description
Cell to transfect:
Designations: COLO 205
Cell Synonyms: : CCL-222, Colo, NCI60, NCI-60, human colon adenocarcinoma cell
Depositors: GE Moore
Growth Properties: mixed, adherent and suspension
Organism: Homo sapiens
Morphology:epithelial
Source: Organ: colon
Tumor Stage: Dukes’ type D
Disease: colorectal adenocarcinoma
Derived from metastatic site: ascites
Cellular Products: carcinoembryonic antigen (CEA) 1.5 to 4.1 ng/10 exp6 cells/10 days; keratin; interleukin 10 (IL-10, interleukin-10)
Applications: transfection host
Tumorigenic: Yes
Age: 70 years
Gender: male
Ethnicity: Caucasian
Comments: This line was isolated in 1975 by T.U. Semple, et al. from ascitic fluid of a 70-year-old Caucasian male with carcinoma of the colon. The cells are positive for keratin by imunoperoxidase staining. COLO 205 cells express a 36000 dalton cell surface glycoprotein related to the GA733-2 tumor associated antigen.
COLO 205 is one of the cell lines of the NCI-60 panel which represents different cancer types and has been widely utilized for drug screening and molecular target identification.
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 COLO 205 Cells
- Highest efficiency to ensure experimental success
- Extremely gentle to cells
- 0.5 ml is able to transfect about 1000 wells of 24-well plate
- Deliver single or multiple plasmids
- 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 COLO 205 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 COLO 205 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 COLO 205 Cell Avalanche® Transfection Reagent.
For Other Cells
COLO 205 Cell Avalanche® Transfection Reagent (human colon adenocarcinoma cell) can also be used on the following cells with high transfection efficiencies.
786-O Cell
Caki-1 Cell
MDCK Cell
Vero Cell
293 Cell
293T/17 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.
