經典案例|普健哺乳動物細胞表達系統之scfv表達

（1）Protein Name: protein L（一種scfv）

該蛋白(bái)不易表達，采用(yòng)哺乳動物細胞表達系統表達活性最佳，其他(tā)表達系統表達活性低(dī)。

（2）Expression vector: pATX2

（3）Expression host: HEK293F

總結：蛋白(bái)L（scfv）采用(yòng)普健高(gāo)表達pATX系列載體配合公司優化高(gāo)密度哺乳表達系統Xten293，成功表達，表達量高(gāo)達31.2mg/L，純度>90%，經檢驗，其具有較高(gāo)活性。

The protein L expressed secretorily in HEK293F cells.

MW. Molecular weight marker. IN. Input.  FT. Flow through. W. Washes. E. Eluted fractions.

A. The purification test result. B. Final QC gel.

L-pATX2 was transfected with 80ml HEK293F cells. The culture medium and cells which were collected on the sixth day post transfection did purification test.
