Embodiment Construction

[0025] An anti-mouse RCN3 protein monoclonal ScFv antibody, the base sequence of the monoclonal ScFv antibody is shown in SEQ ID NO: 10, and the amino acid sequence corresponding to the base sequence is shown in SEQ ID NO: 9.

[0026] The monoclonal ScFv antibody is composed of light chain variable region V L and heavy chain variable region V H Composition, the light chain variable region V L The base sequence of the heavy chain variable region V is shown in SEQ ID NO: 7 H The base sequence is shown in SEQ ID NO:8.

[0027] The heavy chain variable region contains three hypervariable regions, the amino acid sequences of which are shown in SEQ ID NO: 1, SEQ ID NO: 2 and SEQ ID NO: 3 respectively; the light chain variable region V L It contains three hypervariable regions, the amino acid sequences of which are respectively shown in SEQ ID NO: 4, SEQ ID NO: 5 and SEQ ID NO: 6.

[0028] The monoclonal ScFv antibody includes a full-length antibody formed by ScFv through a disul...

Abstract

The invention belongs to the field of biotechnology, and relates to an antibody and development and production of the antibody, in particular to a monoclonal ScFv antibody phage library for resisting mouse RCN3 protein as well as a selecting method of the monoclonal ScFv antibody. The base sequence of the monoclonal ScFv antibody is shown in SEQ ID NO: 10 and the amino acid sequence corresponding to the base sequence is shown in SEQ ID NO:9. The invention discloses construction and selecting methods of the antibody phage library which has high affinity to mouse RCN3 protein, is displayed on phage surfaces and can be used for efficient screening, sequences of the antibody and eukaryotic expression and antigen detection methods. The ScFv antibody which can realize specific recognition and combines the mouse RCN3 protein molecules can be selected with the selecting method, and the antibody screened by the construction and selecting methods has wide application prospect for detection and disease control related to RCN3 protein.

Description

technical field [0001] The invention belongs to the field of biotechnology, relates to the development and production of an antibody and antibody medicine, in particular to an anti-mouse RCN3 protein monoclonal ScFv antibody and its panning method, the sequence and eukaryotic expression of the anti-mouse RCN3 protein antibody Methods with antigen detection. Background technique [0002] mouse RCN3 It is a single-copy gene with sequence number BC055903, located on chromosome 7 of the mouse, containing 7 exons, encoding 328 amino acids. Studies have shown that RCN3 protein is located in the endoplasmic reticulum secretion pathway of mice, an endoplasmic reticulum calcium ion-binding protein containing six EF-hand domains, and is related to the proliferation of lung type I and type II proteins. The gene deletion homozygous mice with artificial knockout of this gene will have shortness of breath and die of purple dryness after delivery. The symptoms are similar to those of ped...
