| Abstract: | The variable region genes of heavy chain and light chain antibody from monoclonal hybridoma cells against human breast cancer were jointed and cloned. Single chain FV antibodies of anti breast cancer were expressed as fusion to phage in phage display system. Panning and screening of phage displaying recombinant ScFV was carried out by means of stringent several round positive and negative selections using related breast tumor cell line and non related tumor cell line. The obtained gene of ScFV that has tumor binding specificity and high affinity could construct recombinant immunotoxin. These anti breast cancer ScFVs are promising for further studying in breast cancer therapy. |
