Isolation of Monoclonal Antibodies with Predetermined Conformational Epitope Specificity

Isolation of Monoclonal Antibodies with Predetermined Conformational Epitope Specificity

Existing technologies allow isolating antigen-specific monoclonal antibodies (mAbs) from B cells. We devised a direct approach to isolate mAbs with predetermined conformational epitope specificity, using epitope mimetics (mimotopes) that reflect the three-dimensional structure of given antigen subdomains. We performed differential biopanning using bacteriophages encoding random peptide librarie...

Monoclonal Antibodies with Broad Specificity

Isolation of human erythropoietin with monoclonal antibodies.

Human erythropoietin was isolated from urine of aplastic anemic patients in a high yield with a simple purification procedure using an immunoadsorbent column of monoclonal antibodies and a Sephadex G-100 column. About 6 mg of erythropoietin was isolated from 700 liters of urine and the specific activity was estimated to be 81,600 units/mg of protein with an in vivo 59Fe incorporation assay meth...

Monoclonal Antibodies

SUMMARY Monoclonal Antibodies are identical antibodies and Can be generated in ultimated amounts by countinuos cultures of single antibody- secreting cells. These cell lines are produced by cell fusion of normal lymphocytes to cells of a myeloma tumor cell line, which confers on the antibody producing hybrid cell, immortality and the ability grow as atumor in animals. monoclonal antibodies c...

Epitope Specificity of Anti-Citrullinated Protein Antibodies

Anti-citrullinated protein antibodies are primarily associated with a progressive course in the autoimmune disease rheumatoid arthritis, a disease with a chronic and inflammatory nature. These antibodies do not appear to have any strict dependency for reactivity except from the presence of the non-genetically encoded amino acid citrulline, which is the result of a posttranslational modification...
