Basic Information

Common name
B-hGAS6 MC38
Catalog number
Colon carcinoma
Tissue types
B-hGAS6 MC38 cells have the capability to establish tumors in vivo and can be used for efficacy studies.


The human GAS6 CDS was inserted into mouse Gas6 gene, so that the mouse Gas6 was not expressed anymore, human GAS6 was expressed in B-GAS6 MC38 cells.

Targeting strategy

Gene targeting strategy for B-hGAS6 MC38 cells. The exogenous promoter and human GAS6 coding sequence was inserted to replace part of murine exon 1 and all of exon 2. The insertion disrupts the endogenous murine Gas6 gene, resulting in a non-functional transcript.

Protein expression analysis

GAS6 expression analysis in B-hGAS6 MC38 cells by ELISA. Supernatant from wild-type MC38 and B-hGAS6 MC38 cultures were stained with species-specific anti-GAS6 antibody. Human GAS6 was detected in the supernatant of B-hGAS6 MC38 cells but not wild-type MC38 cells. The 8-H12 clone of B-hGAS6 MC38 cells was used for in vivo experiments.

Tumor growth curve & Body weight changes

Subcutaneous homograft tumor growth of B-hGAS6 MC38 cells. B-hGAS6 MC38 cells (5×105) and wild-type MC38 cells (5×105) were subcutaneously implanted into C57BL/6N mice (female, 6-week-old, n=6). 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-hGAS6 MC38 cells were able to establish tumors in vivo and can be used for efficacy studies.

Protein expression analysis of tumor cells

B-hGAS6 MC38 cells were subcutaneously transplanted into C57BL/6 mice (n=6), and on 35 days post inoculation, tumors were harvested and assessed for GAS6 expression by ELISA. As shown, human GAS6 was highly expressed by tumor cells. Therefore, B-hGAS6 MC38 cells can be used for in vivo efficacy studies.
