Monoclonal) antibodies Other characteristics of late endosomes are unique lipids or proteins associated with the different compartments. These can be used as a target for (monoclonal) antibodies. Often, also the recombinant GFP-fusion proteins are available (such as GFP-Rab5 and GFP-RhoB). 

Probes can be antibodies, other binding proteins constructed from protein fusions, or even oligonucleotide aptamers. While completion of the Human Genome Project has enabled access to content for nuclide acid arrays, the content for protein arrays is largely based upon available antibody libraries. Thus, the commercialization of protein microarrays remains largely dependent upon both commercial and institutional providers of protein content. These providers must also permit access to the data-based protein annotations. These are necessary in order for the protein array to be useful as a bioinformatics tool.

It can be deduced from Table 39.1 that most biopharmaceuticals approved to date are monoclonal antibodies and the most common indication is oncology. However, barring oncology, the biopharmaceuticals span an impressive range of indications. In addition to monoclonal antibodies, other prevalent types of biopharmaceuticals are fusion or conjugate proteins, growth factors, replacement enzymes, and peptides. Cellular and tissue therapies are rarer but becoming more prevalent. 

The present discussion is mainly concerned with the humoral response. Although many cells participate in this response, the site of antibody production is in B lymphocytes which, in their mature form, are called plasma cells. Each plasma cell produces antibodies with a given specificity, and there are many identical copies, or clones, of this cell type, all making the same monoclonal antibody. Other lines of plasma cells produce antibodies that recognise the same antigen, but have different... 

The basic principle of hybridoma technology is shown in Fig. 2.23. B cells obtained from the spleens of mice immunized with the antigen of interest are fused with estabhshed mouse myeloma cells. Myeloma cells are transformed cancerous cells of the B lymphocyte lineage with infinite growth capacity. While many myeloma cell hnes continue to secrete their antibody, others lose the ability to produce antibodies. Spleen cells from immunized animals are fused with non-antibody-producing myeloma cells, resulting in a hybrid cell which inherits the properties of both the fusion partners. Thus the hybrids are capable of continued growth in culture like the myeloma cell and also maintain the antibody production of the spleen B cell. 

Antinuclear antibody In autoimmune diseases plasma cells prodnee antibodies that are directed against one s own tissnes. These may be detected in patients with a variety of autoimmune diseases. More than 95% of patients with systemic lupus have a positive antinuclear antibody. Other disorders with a positive antinuclear antibody include Sjogren s disease (70%) and rheiunatoid arthritis (40%), both potential causes of uveitis. 

Fully human antibodies can be constructed from phage libraries. In addition to the diversity of engineered antibodies, other molecules can be attached to the antibody, such as enzymes, toxins, viruses, radionuclides, and biosensors for targeting, imaging, or diagnosing. These are commonly referred to as conjugated" monoclonal antibodies.

Cyclic voltammograms of working electrodes in the presence of antibodies other than anli-bioiin IgG produced no anodic peaks. For analyte solutions contain ing anti-biotin IgG, CV peak currents were proportional to the concentration of the analyie. and working dose-response curves of CV peak current versus concentration provided an effective means for completing the immunoassay. The detection limii is O.l pg/ml.. and the range of the technique is 0.1 to 1(K) pg/mL of anii-bioiin IgG. 

Various lipidic markers have been studied (Narula and Strauss, 2005) native low-density lipoprotein (LDL), oxidized LDL, and anti-LDL antibodies. Other components such as cholesterol esters or apoprotein B (Kritz et al, 1998) were marked. 

Recent studies have shown that greater accuracy in the diagnosis of Q fever can be achieved by looking at specific levels of classes of antibodies other than IgG, namely IgA and IgM. Combined detection of IgM and IgA in addition to IgG improves the. specificity of the assays and provides better accuracy in diagnosis. IgM levels are helpful in the determination of a recent infection. In acute Q fever, patients will have IgG antibodies to phase II and IgM antibodies to phases I and II. Increased IgG and IgA antibodies to phase I are often indicative of Q fever endocarditis.

The bags employed in single use bioreactors are presterilized prior to use in cultivation of cells. Several forms of disposable bag bioreactors are available from multiple vendors. Examples include physically stirred bag bioreactors and wave-mixed bag bioreactors. A schematic diagram of a wave-mixed bag bioreactor is shown in Figure 13.13. Bag bioreactors are used in the production of therapeutic recombinant proteins and monoclonal antibodies. Other types of single use bioreactors include permselective membrane reactors in both hollow-fiber and flat-sheet membrane configurations (see Section 13.2.7). 

Because mouse antigens rapidly induce an immune response in humans, methods have been developed to humanize mAbs. One approach involves the production of chimeric antibodies. Other methods now produce fuUy humanized antibodies. 

Although the direct interaction with tryptophan may well account for part of the energy of interaction of Dnp or Tnp haptens with antibody, other forces are undoubtedly operative as well. The energy of interaction of haptens with free tryptophan is only a fraction ( 10%) of the energy of interaction with antibody (88). 

Studies Acetylcholine receptor binding and blocking antibodies were positive, as was the anti-striated-muscle antibody. Other immunological parameters were normal, as were thyroid function tests. Repetitive nerve stimulation at low-frequency (3 Hz) showed an 18% decremental response of the compound-motor-unit potential indicating MG (normal is < 11 % decrement). Nerve conduction studies were normal. Computed tomography (with contrast) of the mediastinum revealed a mass, presumably thymoma.
