RBL-2H3 Cell Avalanche™ Transfection Reagent (rat leukemia cell)

Catalog Number:EZT-RBL2-1
Cell Synonyms:CRL-2256

Cell Line Information:

Designations: RBL-2H3
Depositors: RP Siraganian
Growth Properties: adherent
Organism: Rattus norvegicus deposited as Rattus sp.
Morphology: fibroblast
Source: peripheral blood
Strain: Wistar
Disease: basophilic leukemia
Cell Type: basophil; chemically induced
Cellular Products: histamine
Applications: transfection host
Receptors: FcERI (Fc of IgE)
Comments: RBL-2H3 is a basophilic leukemia cell line isolated and cloned in 1978 from Wistar rat basophilic cells that were maintained as tumors.
These cells have high affinity IgE receptors. They can be activated to secrete histamine and other mediators by aggregation of these receptors or with calcium ionophores. They have been used extensively to study FcERI and the biochemical pathways for secretion in mast cells. They have also been used extensively for studies of different aspects of secretion in cells including the role of changes in intracellular calcium, the activation of phospholipases, protein kinases and small G proteins.

The Transfection Reagent:

RBL-2H3 Cell Avalanche™ Transfection Reagent is a new class of unique chemical formulations specifically formulated and optimized for transfecting RBL-2H3 Cells. The proprietary formulation of lipids and polymers ensures the highest possible transfection efficiencies and viabilities for RBL-2H3 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?

FIG. 1. High throughput test of transfection efficiency (determined as RLU/mg) on RBL-2H3 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 RBL-2H3 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 RBL-2H3 Cell Avalanche Transfection Reagent.

For Other Cells:
RBL-2H3 Cell Avalanche™ Transfection Reagent (rat leukemia cell) can also be used on the following cells with high transfection efficiencies.

786-O Cell
Caki-1 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.
