Purification of TEM-1 beta-lactamase by immunoaffinity chromatography.
A monoclonal antibody prepared against TEM-1 beta-lactamase was found to compete with penicillins and cephalosporins for binding to the enzyme. The purified antibody preparation was linked to Sepharose 4B and used for immunoaffinity-chromatography purification of TEM-1 beta-lactamase. Elution with either benzylpenicillin or cloxacillin yielded a highly purified, concentrated and active enzyme p...
متن کاملEnhanced production of pediocin PA-1 and coproduction of nisin and pediocin PA-1 by Lactococcus lactis.
The production and secretion of class II bacteriocins share a number of features that allow the interchange of genetic determinants between certain members of this group of antimicrobial peptides. Lactococcus lactis IL1403 encodes translocatory functions able to recognize and mediate secretion of lactococcin A. The ability of this strain to also produce the pediococcal bacteriocin pediocin PA-1...
متن کاملIsolation and purification of HLA-DR antigen from Daudi cell line by immunoaffinity chromatography
Introduction: The major histocompatibility complex (MHC) is a group of cell surface proteins that are essential for recognizing foreign molecules in human and other mammals. The physiologic function of MHC molecules is the presentation of peptides to T cells. In this study, we evaluated the purification of a class II MHC molecule (HLA-DR) from a human Burkitt′s lymphoma cell line; Daudi...
متن کاملPurification of nucleotide-requiring enzymes by immunoaffinity chromatography.
Monospecific (affinity-purified) anti-(yeast glucose-6-phosphate dehydrogenase) IgG inhibits three different NADPH-requiring enzymes, chicken liver dihydrofolate reductase, pigeon liver fatty acid synthetase and chicken liver malic enzyme. The inhibition of all three enzymes was approx. 50% in a 2h incubation with 100 micrograms of IgG. Similarly, with several different NADH-requiring enzymes, ...
متن کاملOne-step purification of nisin A by immunoaffinity chromatography.
The lantibiotic nisin A was purified to homogeneity by a single-step immunoaffinity chromatography method. An immunoadsorption matrix was developed by direct binding of anti-nisin A monoclonal antibodies to N-hydroxysuccinimide-activated Sepharose. The purification procedure was rapid and reproducible and rendered much higher final yields of nisin than any other described method.
