Generation and characterization of human monoclonal single chain variable fragments (scFvs) against envelope third variable region (V3) of HIV-1 clade C

چکیده
Methods A phage library of 7000 clones was constructed from a drug naive HIV-1 clade C infected Indian patient whose plasma exhibited high potential neutralizing potential against a panel of viruses and also displayed cross-reactive anti-V3 antibodies. PBMCs were isolated and EBV transformed. Cells (wells) producing anti-V3 antibodies were preselected with V3-CTB fusion protein and expanded. Total RNA was isolated and cDNA was constructed followed by VH and VL amplification. scFvs were constructed, cloned into phagemid vector and expressed in Escherichia coli. We assessed the expression of the scFvs by SDSPAGE and Western blotting. Specificity was examined by ELISA.

A novel strategy for efficient production of anti-V3 human scFvs against HIV-1 clade C
BACKGROUND Production of human monoclonal antibodies that exhibit broadly neutralizing activity is needed for preventing HIV-1 infection, however only a few such antibodies have been generated till date. Isolation of antibodies by the hybridoma technology is a cumbersome process with fewer yields. Further, the loss of unstable or slowly growing clones which may have unique binding specificities...
متن کاملProduction and Evaluation of Specific Single-Chain Antibodies against CTLA-4 for Cancer-Targeted Therapy
Background: Cytotoxic T lymphocyte–associated antigen 4 (CTLA-4) molecules are expressed on T-cells and inhibit their function by inhibiting activation of subsequent T-cell molecular pathways. Blocking of CTLA-4 inhibits the growth of malignant tumor cells. Anti-CTLA-4 monoclonal antibodies activate the immune system against cancer. Due to several advantages of single-chain antibodi...
متن کاملSelection of single-chain variable fragments specific for Mycobacterium tuberculosis ESAT-6 antigen using ribosome display
Objective(s): Tuberculosis (TB) is still one of the problematic infectious diseases in developing countries, especially in Iran. In the present study, we applied ribosome display technique to select single chain variable fragments (scFvs) specific for the 6-kDa early secretory antigenic target (ESAT-6) antigen of Mycobacterium tuberculosis from a mouse scFv library. Materials and Methods: The g...
متن کاملDeterminants of human immunodeficiency virus type 1 envelope glycoprotein activation by soluble CD4 and monoclonal antibodies.
Infection by some human immunodeficiency virus type 1 (HIV-1) isolates is enhanced by the binding of subneutralizing concentrations of soluble receptor, soluble CD4 (sCD4), or monoclonal antibodies directed against the viral envelope glycoproteins. In this work, we studied the abilities of different antibodies to mediate activation of the envelope glycoproteins of a primary HIV-1 isolate, YU2, ...
متن کاملSelection of recombinant, library-derived antibody fragments against p24 for human immunodeficiency virus type 1 diagnostics.
By application of combinatorial library technology, we generated the first recombinant antibody fragments directed against the major capsid protein p24 of human immunodeficiency virus type 1 (HIV-1). A library of single-chain Fv fragments (scFvs) was constructed by using the antibody variable-region (V) genes of B cells derived from the spleen of a viral lysate-immunized mouse. Antibodies were ...
