Basic Information

Common Name
B-hPD-L2 MC38
Catalog Number
Cell Type/Disease
Colon Carcinoma
Mus musculus, C57BL/6


The mouse PD-L2 gene was replaced by human PD-L2 coding sequence in B-hPD-L2 MC38 cells. Human PD-L2 is highly expressed on the surface of B-hPD-L2 MC38 cells.

Targeting strategy

The exogenous promoter and human PD-L2 coding sequence was inserted to replace part of murine exon 3. The insertion disrupts the endogenous murine PD-L2 gene, resulting in a non-functional transcript.

Protein expression analysis

PD-L2 expression analysis in B-hPD-L2 MC38 cells by flow cytometry. Single cell suspensions from wild-type MC38 and B-hPD-L2 MC38 cultures were stained with species-specific anti-PD-L2 antibody. Mouse PD-L2 was not detected on the surface of wild-type MC38 cells. Human PD-L2 was detected on the surface of B-hPD-L2 MC38 cells but not wild-type MC38 cells. The 1-C11 clone of B-hPD-L2 MC38 cells was used for in vivo experiments.

Tumor growth curve

Subcutaneous homograft tumor growth of B-hPD-L2 MC38 cells. B-hPD-L2 MC38 cells (5×105) were subcutaneously implanted into C57BL/6 mice (female, 5-8-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-hPD-L2 MC38 cells were able to establish tumors in vivo and can be used for efficacy studies.
