| Intruduction: | Anti-human CD19 specific single chain antibody (scFv) derived CAR-T therapy has been widely used in both basic research and clinical applications. One of the most commonly used anti-CD19 scFv is derived from hybridoma clone SJ25C1. To develop a specific assay for monitoring its expression after lentivirus mediated host cell transduction, such as human T cells, we have identified a specific SJ25C1 scFv protein sequence binder. It is fused with superGFP protein as SJ25C1 scFv detection reagent in cell based assay, such as flow-cytometry. A unique SJ25C1 specific binder protein was identified using phage-display library, and then fused with superGFP at its N-terminus as a 55.2 kD protein. The final fusion protein HRP-2971 was expressed in E.coli as highly soluble protein, and was chromatographically purified. |
