B-hTNFR2 MC38
Common name
B-hTNFR2 MC38 Catalog number    310723
Aliases CD120b, TBPII, TNFBR, TNFR80, TNFRSF1B Disease  Colon carcinoma
Organism
Mouse
Strain  C57BL/6
Tissue types Colon Tissue  Colon

Description 

The mouse Tnfr2 gene was replaced by human TNFR2 coding sequence in B-hTNFR2 MC38 cells. Human TNFR2 is highly expressed on the surface of B-hTNFR2 MC38 cells.


Targeting strategy


Gene targeting strategy for B-hTNFR2 MC38 cells. The exogenous promoter and human TNFR2 coding sequence was inserted to replace the extracellular region of the mouse. The insertion disrupts the endogenous murine Tnfr2 gene, resulting in a non-functional transcript.

Protein expression analysis

TNFR2 expression analysis in B-hTNFR2 MC38 cells by flow cytometry. Single cell suspensions from wild-type MC38 and B-hTNFR2 MC38 cultures were stained with species-specific anti-TNFR2 antibody. Mouse TNFR2 was detected on the surface of wild-type MC38 cells. Human TNFR2 was detected on the surface of B-hTNFR2 MC38 cells but not wild-type MC38 cells. The 6-D05 clone of B-hTNFR2 MC38 cells was used for in vivo experiments.

Tumor growth curve & Body weight changes

Subcutaneous homograft tumor growth of B-hTNFR2 MC38 cells. B-hTNFR2 MC38 cells (5x105) and wild-type MC38 cells (5x105) were subcutaneously implanted into C57BL/6N mice (female, 6-9-week-old, 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-hTNFR2 MC38 cells were able to establish tumors in vivo and can be used for efficacy studies.
