Characterization of Novel Fragment Antibodies Against TNF-alpha Isolated Using Phage Display Technique
Tumor necrosis factor alpha (TNF-α) is an inflammatory cytokine which plays crucial roles in pathogenesis of inflammatory diseases. The current study aimed to investigate the binding abilities of I44 and I49 domain antibodies to TNF-α. The dAbs were expressed in bacterial expression system and purified by affinity chromatography using Ni-sepharose column. The expression and purity of the protei...

متن کاملDiscovery of Novel Peptidomimetics for Brain-Derived Neurotrophic Factor using Phage Display Technology
Brain-Derived Neurotrophic Factor (BDNF) is a neuroprotectant candidate for neurodegenerative diseases. However, there are several clinical concerns about its therapeutic applications. In the current study, we selected BDNF-mimicking small peptides from phage-displayed peptide library as alternative molecules to the clinical challenges. The peptide library was screened against BDNF receptor (Ne...
متن کاملPhage display for target-based antibacterial drug discovery.
Increasing bacterial drug resistance and hard-to-eradicate opportunistic infections have created a need for new antibiotics. Sequencing of microbial genomes has yielded many new potential targets for antibacterial drug discovery. However, little is known about the biochemical activities of many of these targets, making it difficult to develop HTS assays for them. Peptides isolated by phage disp...
متن کاملMolecular docking and ligand specificity in fragment-based inhibitor discovery.
Fragment screens have successfully identified new scaffolds in drug discovery, often with relatively high hit rates (5%) using small screening libraries (1,000-10,000 compounds). This raises two questions: would other noteworthy chemotypes be found were one to screen all commercially available fragments (>300,000), and does the success rate imply low specificity of fragments? We used molecular ...
