最短37分钟即可从小鼠脾脏或骨髓的单细胞悬液中分离不带磁珠的CD138+浆细胞和浆母细胞。

CD138+细胞是分化的B细胞,能产生亲和性成熟抗体,因此可用于抗体开发研究。用小鼠骨髓和脾细胞融合产生杂交瘤时通常需要筛查数千个克隆,而在杂交瘤融合前先富集CD138+浆细胞可大大减少筛查的工作量。

通过免疫磁珠正选技术纯化CD138+浆细胞和浆母细胞可以提高抗体开发研究的实验效率。无需分离柱,只需用抗体和磁珠标记细胞,将其放入EasySep™磁极中,然后从分选出的CD138+细胞上去除结合的磁珠。从免疫小鼠体内分选出的CD138+细胞纯度高达95%,可用于电融合等杂交瘤生成方法。

Data Figures

Using the EasySep™ Release Mouse CD138 Positive Selection Kit on a single-cell suspension of mouse spleen, the CD138+ purities of the start and final isolated fractions are 0.6% and 77.6% in naïve, and 1.2% and 91.6% in immunized mice, respectively.

Figure 1. EasySep™ Release Mouse CD138 Positive Selection Kit

(A) Starting with naïve C57BL/6 mouse splenocytes, the plasma cell (CD138+CD267 (TACI)+) content of the isolated fraction is typically 77.2 ± 2.4% (mean ± SD using the purple EasySep™ Magnet). In the above example, the purities of the start and isolated fractions are 0.6% and 77.6%, respectively. (B) Starting with immunized BALB/c mouse splenocytes, the plasma cell (CD138+CD267 (TACI)+) content of the isolated fraction is typically 86.1 ± 7.4% (mean ± SD using the purple EasySep™ Magnet). In the above example, the purities of the start and isolated fractions are 1.2% and 91.6%, respectively.

Using the EasySep™ Release Mouse CD138 Positive Selection Kit on a single-cell suspension of mouse bone marrow, the CD138+ purities of the start and final isolated fractions are 0.3% and 71.7% in naïve, and 0.6% and 89.0% in immunized mice, respectively.

C) Starting with naïve C57BL/6 mouse bone marrow, the plasma cell (CD138+CD267 (TACI)+) content of the isolated fraction is typically 62.0 ± 13.1% (mean ± SD using the purple EasySep™ Magnet). In the above example, the purities of the start and isolated fractions are 0.3% and 71.1%, respectively. (D) Starting with immunized BALB/c mouse bone marrow, the plasma cell (CD138+CD267 (TACI)+) content of the isolated fraction is typically 85.5 ± 9.8% (mean ± SD using the purple EasySep™ Magnet). In the above example, the purities of the start and isolated fractions are 0.6% and 89.0%, respectively.

In immunized mice, the % antigen-specific hit rate for total splenocytes or EasySep™-isolated CD138+ cells from splenocytes were 3.2% and 56.1%, respectviely. The % antigen-specific hit rate for total bone marrow or EasySep™-isolated CD138+ cells from bone marrow were 0% and 31.9%, respectviely.

(E) Isolated CD138+ cells or total splenocytes from mice immunized with various antigens were fused with Sp2/0 mouse myeloma cells and plated in semi-solid medium using ClonaCell™-HY Hybridoma Kit (Catalog #03800). The % antigen-specific hit rate was determined by ELISA. The % antigen-specific hit rates for total splenocytes and CD138+ cells were 3.2 ± 4.0% and 56.1 ± 37.2% (mean ± SD), respectively. (F) Isolated CD138+ cells or total bone marrow cells from mice immunized with various antigens were fused with Sp2/0 mouse myeloma cells and plated in semi-solid medium using ClonaCell™-HY Hybridoma Kit (Catalog #03800). The % antigen-specific hit rate was determined by ELISA. The % antigen-specific hit rates for total bone marrow cells and CD138+ cells were 0% and 31.9 ± 46.0% (mean ± SD), respectively.
