COLO 205 Cell Avalanche™ Transfection Reagent (human colon adenocarcinoma cell)

Catalog Number:EZT-COLO-1
Cell Synonyms:CCL-222, Colo, NCI60, NCI-60

Cell Line Information:

Designations: COLO 205
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 mmunoperoxidase 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.

The Transfection Reagent:

Transfection of suspension cells, or suspension/adherent mixed cells, such as COLO 205 Cells, has always been challenging, both technically and financially. The most common systems currently used for molecular delivery to these cells include expensive electroporation instruments and relatively toxic chemical formulations.

COLO 205 Cell Avalanche™ Transfection Reagent is a new class of unique chemical formulations specifically formulated and optimized for transfecting COLO 205 Cells. The proprietary formulation of lipids and polymers ensures the highest possible transfection efficiencies and viabilities for COLO 205 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 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.
