B-hCD47 CT26.WT

Common name	B-hCD47 CT26.WT	Catalog number	310702
Aliases	IAP, MER6, OA3	Disease	Colon carcinoma
Organism	Mouse	Strain	BALB/c
Tissue types	Colon	Tissue	Colon

Description

The mouse Cd47 gene was replaced by human CD47 gene in B-hCD47 CT26.WT cells. Human CD47 is highly expressed on the surface of B-hCD47 CT26.WT cells.

Application

B-hCD47 CT26.WT cells have the capability to establish tumors in vivo and can be used for efficacy studies.

Targeting strategy

Gene targeting strategy for B-hCD47 CT26.WT cells. The IgV domain on exon 2 of mouse Cd47 gene was replaced by the IgV domain of human CD47 on exon 2 in B-hCD47 CT26.WT .

Protein expression analysis

from clipboard

CD47 expression analysis in B-hCD47 CT26.WT cells by flow cytometry. Single cell suspensions from wild-type CT26.WT and B-hCD47 CT26.WT cultures were stained with species-specific anti-CD47 antibody. Human CD47 was detected on the surface of B-hCD47 CT26.WT cells but not wild-type CT26.WT cells. The 1-F12 clone of B-hCD47 CT26.WT cells was used for in vivo experiments.

Tumor growth curve & Body weight changes

from clipboard

Subcutaneous homograft tumor growth of B-hCD47 CT26.WT cells. B-hCD47 CT26.WT cells (1x10⁵) and wild-type CT26.WT cells (1x10⁵) were subcutaneously implanted into BALB/c mice (female, n=5). Tumor volume and body weight were measured twice a week. (A) Average tumor volume ± SEM. (B) Body weight (Mean± SEM). Volume was expressed in mm³ using the formula: V=0.5 X long diameter X short diameter². As shown in panel A, B-hCD47 CT26.WT cells were able to establish tumors in vivo and can be used for efficacy studies.
