Targeting Strategy

Gene targeting strategy for B-CAG-hB7-H4 MC38. The human full-length B7-H4 CDS region was inserted in the B7-h4 exon3~4 of wild-type MC38.

Details

Protein expression analysis

The B7-H4 expression analysis in B-CAG-hB7-H4 MC38 cells by flow cytometry. Single cells were collected from wild-type MC38 and B-CAG-hB7-H4 MC38 cells, and analyzed by flow cytometry with species-specific anti-B7-H4 antibody. Human CD47 was detectable in B-CAG-hB7-H4 MC38 cells but not wild-type MC38 cells.

Tumor Growth Curve & Body Weight Changes

Subcutaneous xenograft tumor growth of B-CAG-hB7-H4 MC38 cells. B-CAG-hB7-H4 MC38 cells and wild-type MC38 cells (5×105) were subcutaneously implanted into the C57BL/6N mice (female, 7-9 week-old, n=5).Tumor size and mice body weight were measured twice a week. (A) Tumor average volume ± SEM, (B) Mice body weight (Mean± SEM). Volume was expressed in mm3 using the formula: V=0.5a X b2, where a and b were the long and short diameters of the tumor, respectively. As shown in panel A, B-CAG-hB7-H4 MC38 were able to establish tumor in vivo and can be used for efficacy study.

Tumor expression detection sample information

Protein expression analysis in tumor cells

Note:

FMO Control 1: MC38 tumor cells only stained anti-hB7-H4 antibody;

FMO Control 2: B-CAG-hB7-H4 MC38 cells only stained anti-mB7-H4 antibody;

FMO Control 3: MC38 cells only stained anti-hB7-H4 antibody.

B-CAG-hB7-H4 MC38 cells were transplanted into C57BL/6N mice(n=5), and on 42 days post inoculation, certain volumes of tumors as was taken to detect the expression level of the cells. As Shown,human B7-H4 was highly expressed on the surface of tumor cells. B-CAG-hB7-H4 MC38 can be used for in vivo efficacy validation.
