Model Description

The hBCMA(BALB/c) (NM-HU-241173) was crossed with hCD3EDG(BALB/c)(NM-HU-220122) to generate hBCMA(BALB/c)/hCD3EDG(BALB/c) mice.

Fig.1 Detection of hBCMA expression on TACI+CD138+ cells in spleen and bone marrow of WT BALB/c mice and HO hCD3EDG/hBCMA(BALB/c) mice by FACS. Leukocytes were collected from wild-type BALB/c mice (female, 8 weeks old) and homozygous hCD3EDG/hBCMA(BALB/c) humanized mice (female, 7 weeks old), and analyzed by flow cytometry with anti-hBCMA. 

Abbr. HO, homozygous; WT, wild type.
