B-hTPBG CT26.WT
Common name
B-hTPBG CT26.WT Catalog number    322280
Aliases 5T4 Disease  Colon carcinoma
Organism
Mouse 
Strain  BALB/c
Tissue types Colon Tissue  Colon
Description 

The mouse Tpbg gene was replaced by human TPBG coding sequence in B-hTPBG CT26.WT cells. Human TPBG is highly expressed on the surface of B-hTPBG CT26.WT cells.

Application

B-hTPBG 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-hTPBG CT26.WT cells. The exogenous promoter and human TPBG coding sequence was inserted to replace part of murine Tpbg exon 2. The insertion disrupts the endogenous murine Tpbg gene, resulting in a non-functional transcript.

Protein expression analysis 

from clipboard

TPBG expression analysis in B-hTPBG CT26.WT cells by flow cytometry. Single cell suspensions from wild-type CT26.WT and B-hTPBG CT26.WT cultures were stained with species-specific anti-TPBG antibody. Human TPBG was detected on the surface of B-hTPBG CT26.WT cells but not wild-type CT26.WT cells. The 4-H05 clone of B-hTPBG CT26.WT cells was used for in vivo experiments.

Tumor growth curve & Body weight changes

Subcutaneous homograft tumor growth of B-hTPBG CT26.WT cells. B-hTPBG CT26.WT cells (1x105) and wild-type CT26.WT cells (1x105) were subcutaneously implanted into BALB/c mice (female, 6-week-old, n=8). 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-hTPBG CT26.WT cells were able to establish tumors in vivo and can be used for efficacy studies.

B-hTPBG CT26.WT tumor cells growth of individual mice. B-hTPBG CT26.WT cells (1x105) and wild-type CT26.WT cells (1x105) were subcutaneously implanted into BALB/c mice (female, 6-week-old, n=8). As shown in panel, B-hTPBG CT26.WT cells were able to establish tumors in vivo and can be used for efficacy studies.

Protein expression analysis of tumor cells

B-hTPBG CT26.WT cells were subcutaneously transplanted into BALB/c mice. At the end of the experiment, tumor cells were harvested and assessed for human TPBG expression by flow cytometry. As shown, human TPBG was highly expressed on the surface of tumor cells. Therefore, B-hTPBG CT26.WT cells can be used for in vivo efficacy studies of novel TPBG therapeutics.
