B-hCD19-luc GFP A20

Common name	B-hCD19-luc GFP A20	Catalog number	322286
Aliases	/	Disease	Reticulum cell sarcoma
Organism	Mouse	Strain	BALB/cAnN
Tissue types	Lymphoma	Tissue	B lymphocyte

Description

The mouse Cd19 gene was replaced by human CD19 coding sequence in B-hCD19-luc GFP A20 cells. Human CD19 is highly expressed on the surface this cell. And this cell expresses firefly luciferase as a marker.

Application

B-hCD19-luc GFP A20 cells can be used for efficacy studies in B lymphoma.

Targeting strategy

Gene targeting strategy for B-hCD19-luc GFP A20 cells. The exogenous promoter, human CD19 coding sequence and luciferase was inserted to replace part of murine Cd19 gene in B-hCD19-luc GFP A20 cells. Mouse Cd19 transcript was disrupted, the protein no longer be expressed.

Protein expression analysis

from clipboard

CD19 expression analysis in B-hCD19-luc GFP A20 cells by flow cytometry. Single cell suspensions from wild-type A20 and B-hCD19-luc GFP A20 cultures were stained with anti-CD19 antibody. Human CD19 was detected on the surface of B-hCD19-luc GFP A20 cells but not wild-type A20 cells. And mouse CD19 was not detected on B-hCD19-luc GFP A20 cells.

In vitro luciferase activity of B-hCD19-luc GFP A20 cells

from clipboard

Luminescence signal intensity of B-hCD19-luc GFP A20 cells. Luminescence intensity was measured using the Bright-GloTM luciferase Assay (Promega, Cat E2610). B-hCD19-luc GFP A20 cells have strong luminescence signal.
