1. Engineered scPDL1-DM1 drug conjugate with improved in vitro analysis to target PD-L1 positive cancer cells and intracellular trafficking studies in cancer therapy
Abstract Antibody-drug conjugates (ADC), precisely deliver a cytotoxic agent to antigen-expressing tumor cells by using specific binding strategies of antibodies. The ADC has shown the ability of potent bio-therapeutics development but indefinite stoichiometric linkage and full-length antibody penetration compromised the field of its advancement. Single chai

2. Cultivation of Pichia pastoris carrying the scFv anti LDL (-) antibody fragment. Effect of preculture carbon source
Abstract Antibodies and antibody fragments are nowadays among the most important biotechnological products, and Pichia pastoris is one of the most important vectors to produce them as well as other recombinant proteins. The conditions to effectively cultivate a P. pastoris strain previously genetically modified to produce the single-chain variable fragment a

3. Novos biomarcadores para o diagnóstico não invasivo do carcinoma oral de células escamosas
CAPÍTULO I: A detecção precoce do carcinoma oral de céulas escamosas (OSCC) é fator importante na diminuição das taxas de mortalidade e o sucesso do tratamento relaciona-se diretamente com seu diagnóstico em fases iniciais. Contudo, infelizmente, a maioria dos carcinomas orais é diagnosticada em fases tardias da doença. No presente trabalho, pela p

4. ConstruÃÃo de uma biblioteca de anticorpos (scFv) apresentada em fagos para seleÃÃo, anÃlise e caracterizaÃÃo de antÃgenos do carrapato bovino (Boophilus microplus)
CAPÃTULO I: The amplification of fragmentos scFv (single chain fragments variable) of immunized animals is an important method to generation of monoclonal antibodies. In this work chickens had been immunized with proteins of the larval and adult phases of the Boophilus microplus for the generation of an antibodies combinatorial library. Total RNA of spleen

5. Construção de uma biblioteca de anticorpos (scFv) apresentada em fagos para seleção, análise e caracterização de antígenos do carrapato bovino (Boophilus microplus)
CAPÍTULO I: A amplificação de fragmentos scFv (fragmentos variáveis de cadeia única) de animais imunizados é um importante método na geração de anticorpos monoclonais. Neste trabalho galinhas foram imunizadas com proteínas totais das fases larval e adulta (teleóginas) do carrapato bovino Boophilus microplus para a geração de uma biblioteca combi

6. A label-free immunosensor array using single-chain antibody fragments
We report a microcantilever-based immunosensor operated in static deflection mode with a performance comparable with surface plasmon resonance, using single-chain Fv (scFv) antibody fragments as receptor molecules. As a model system scFv fragments with specificity to two different antigens were applied. We introduced a cysteine residue at the C terminus of e

7. Human anti-self antibodies with high specificity from phage display libraries.
Recently we demonstrated that human antibody fragments with binding activities against foreign antigens can be isolated from repertoires of rearranged V-genes derived from the mRNA of peripheral blood lymphocytes (PBLs) from unimmunized humans. The heavy and light chain V-genes were shuffled at random and cloned for display as single-chain Fv (scFv) fragment

8. Differentiation of Candida albicans and Candida dubliniensis by Using Recombinant Human Antibody Single-Chain Variable Fragments Specific for Hyphae
To identify antigens specific for the filamentous form of Candida albicans, a combinatorial phage display library expressing human immunoglobulin heavy and light chain variable regions was used to select phage clones capable of binding to the surfaces of viable C. albicans filaments. Eight distinct phage clones that bound specifically to filament surface ant

9. Construction of a semisynthetic antibody library using trinucleotide oligos.
A semisynthetic antibody library composed of single chain Fv fragments (scFv) was constructed by replacing the heavy chain CDR3 region of a human scFv by a random sequence of eight amino acids using trinucleotide codons. After cloning into a phage display vector, an antibody library was generated with a complexity of 8 x 10(8) independent clones. The library

10. Production and fluorescence-activated cell sorting of Escherichia coli expressing a functional antibody fragment on the external surface.
We have expressed a single chain Fv (scFv) antibody fragment, consisting of the variable heavy and variable light domains from two separate anti-digoxin monoclonal antibodies, on the external surface of Escherichia coli by fusing it to an Lpp-OmpA hybrid previously shown to direct heterologous proteins to the cell surface. This scFv fusion was expressed at a

11. Specificity tuning of antibody fragments to neutralize two human chemokines with a single agent
Chemokines are important mediators of the immune response that are responsible for the trafficking of immune cells between lymphoid organs and migration towards sites of inflammation. Using phage display selection and a functional screening approach, we have isolated a panel of single-chain fragment variable (scFv) capable of neutralizing the activity of the

12. Comparison of fusion phage libraries displaying VH or single-chain Fv antibody fragments derived from the antibody repertoire of a vaccinated melanoma patient as a source of melanoma-specific targeting molecules
A single-chain Fv (scFv) fusion phage library derived from random combinations of VH and VL (variable heavy and light chains) domains in the antibody repertoire of a vaccinated melanoma patient was previously used to isolate clones that bind specifically to melanoma cells. An unexpected finding was that one of the clones encoded a truncated scFv molecule wit
