A stepwise approach to the development of artificial O6-alkylguanine-DNA alkyltransferases (AGTs) and its application to the in vitro selection of antibodies with highly reactive cysteine residues are described. As a result of low reactivity of O6-alkylate ...
Production of human monoclonal autoantibodies to glutamic acid decarboxylase Mr 65,000 (GAD65), characterization of their isotype, binding affinity, V region sequences and competition with autoantibodies in patients' sera is described. Lymphocytes from a p ...
The final glycosylation pattern of recombinant proteins might be determined by the choice of the host cell, cell culture conditions and the purification. Each step influences glycosylation and improved glycosylation of the product may thus be obtained by c ...
Viruses that induce chronic infections can evade immune responses. HIV is a prototype of this class of pathogen. Not only does it mutate rapidly and make its surface components difficult to access by neutralizing antibodies, but it also creates cellular hi ...
Monoclonal antibodies (Mabs) are valuable reagents for the purification, characterization and immunolocalization of proteins.In this study, we raised Mabs against human peroxisome proliferator-activated receptors (PPARs) using baculovirus particles display ...
The present study investigates the respective roles of both the host immune response and the metabolic requirements in determining the long-term survival of erythropoietin-secreting myoblasts within encapsulating polymer membranes. Hollow-fiber capsules lo ...
Using transient expression, high amounts (>20 mg/mL) of secreted anti-human Rhesus-D IgG1 were produced in a suspension-adapted HEK293 EBNA cell line (Meissner et al., Biotechnol Bioeng 75: 197-203, 2001). Time of harvest was 3 days after transfection. For ...
This is the first report of two successful 100 l scale transienttransfections in a standard stirred bioreactor. More than half a gram of a monoclonal antibody (IgG) were produced in less than 10 days using a technology called large-scale transient gene exp ...
Type 1 diabetes is a T cell-mediated disease in which B cells serve critical Ag-presenting functions. In >95% of type 1 diabetic patients the B cell response to the glutamic acid decarboxylase 65 (GAD65) autoantigen is exclusively directed at conformationa ...
Human colon carcinoma Caco-2 cell monolayers undergo conversion into cells that share morphological and functional features of M cells when allowed to interact with B lymphocytes. A lymphotropic (X4) HIV-1 strain crosses M cell monolayers and infects under ...
