Antibodies are proteins with the ability to bind antigens rapidly and specifically. Antibodies consist of several different parts. The complementary determining regions (CDR) are the parts that recognize the antigen are the focus of this study. The aims of this study were to synthesize and produce a single-chain antibody (scFv) of the anti-cytokeratin 8 monoclonal IgG antibody TS1 and to functi...
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...
introduction: gastric cancer, as the second reason of cancer mortality around the world, is defined as one of the serious health problems and a wide range of current research is focused to overcome the challenges relevant to its successful therapy. employing recent approaches in the field of vaccine tumor therapy and immunotherapic strategies such as utilization of monoclonal antibodies can pla...
Abstract Beyond cell-cell contact, communication at a distance requires the secretion of cytokines that bind to specific receptors on responsive cells. Interleukin (IL)-9 is cytokine with pleiotropic effects not only immune cells contribute progression tumor and autoimmunity, but also structural including airway intestinal epithelial involved in development inflammatory allergic diseases. Typic...
Although combinatorial antibody libraries have solved the problem of access to large immunological repertoires, efficient production of these complex molecules remains a problem. Here we demonstrate the efficient expression of a unique large single-chain (lsc) antibody in the chloroplast of the unicellular, green alga, Chlamydomonas reinhardtii. We achieved high levels of protein accumulation b...
Hemagglutinin is a major glycoprotein of Porphyromonas gingivalis vesicles and likely confers the ability to adsorb and penetrate into host tissue cells. To protect this bacterial invasion, murine monoclonal antibody (MAb) Pg-vc, which inhibited the hemagglutinating activity, was prepared by using P. gingivalis vesicles as an antigen. Western blot analysis revealed that when both MAb Pg-vc and ...
Antibody single-chain variable fragments (scFvs) are used in a variety of applications, such as for research, diagnosis and therapy. Essential for these applications is the extraordinary specificity, selectivity and affinity of antibody paratopes, which can also be used for efficient protein purification. However, this use is hampered by the high affinity for the protein to be purified because ...
The therapeutic use of antibodies is restricted by the limited access of antibodies to intracellular compartments. To overcome this limitation, we developed a cell-penetrating monoclonal antibody, mAb 3E10, as an intracellular delivery vehicle for the intracellular and intranuclear delivery of antibodies constructed as bispecific single-chain Fv fragments. Because MDM2 is an important target in...
Targeted measurements of low abundance proteins in complex mixtures are in high demand in many areas, not the least in clinical applications measuring biomarkers. We here present the novel platform AFFIRM (AFFInity sRM) that utilizes the power of antibody fragments (scFv) to efficiently enrich for target proteins from a complex background and the exquisite specificity of SRM-MS based detection....
