![]() ![]() The main difference between immune imaging and standard imaging is that, rather than imaging a large, nonspecific section of the body, a tagged antibody targets a precise location for diagnostic imaging instead. Some common imaging methods include positron emission tomography (PET), magnetic resonance imaging (MRI), fluorescent molecular tomography (FMT) and ultrasound. Most antibody-based in vivo diagnostics are used for highly specific imaging. In vivo diagnostics are a noninvasive way for clinicians to diagnose disease progression through analysis of biomarkers within the body rather than through biologic samples inside a laboratory. The reason for this preference is likely attributed to the natural ability of the murine immune system to generate highly specific mAbs that elicit strong constant domain functionality with limited immunoreactivity after humanization. Interestingly, despite the discovery of combinatorial display libraries in 1984 as an alternative mAb discovery platform, the majority of these mAb therapeutics were originally discovered using hybridoma technology in either fully murine or humanized mice. Since the approval of muromonab-CD3 in 1986, the FDA has approved approximately 80 more mAb therapeutics for diseases ranging from autoimmune disorders, to inflammatory diseases, HIV and cancer. While the first few US FDA-approved mAb therapeutics, such as muromonab-CD3, were generated solely in mice, it became evident that in order to avoid immune rejection, future mAb-based therapeutics needed to undergo humanization. Due to this high affinity and specificity, researchers began investigating the therapeutic potential of mAbs as metabolic activators, inhibitors and immuno-modulators. Ascites fluid will be contaminated with mouse imunoglobulins to a small extent and if a very pure antibody is required this may prove inconvenient.Īpplications of Hybridoma Technology mAb therapeuticsĬompared with other biologics, mAbs are able to maintain an extremely high affinity towards their target. It is possible to obtain 10 ml of ascites fluid or more from a mouse by regular tapping. The ascites fluid can be collected from an anaesthetized mouse. The rate of growth of the resulting ascites tumour is in general very variable and can be from less than two or more than five weeks. Sino Biological can offer serum-free hybridoma production serivce by the use of serum-free medium.įor producing monoclonal antibodies in vivo, mice are primed by intraperitoneal injection with 10 5 - 10 7 hybridoma cells. Culture in vitro provides a more pure preparation of antibody. Typical culture supernatants yield up to l00μg/ml of antibody, the exact amount depending upon the cell density and rate of growth. The cell density is maintained between 10 5 and 10 6 cells/ml. Hybridoma antibodies can be produced in vitro and in vivo.įor production of monoclonal antibodies in vitro, hybridomas are expanded by transfer to 24 well tissue culture plates followed by 25 cm 2 flask and a 75 cm 2 flask containing suitable medium.
