Heavy/Light-chain analysis of monoclonal gammopathies.
Monoclonal gammopathies (M proteins) are associated with an extraordinarily broad array of clinical conditions that range from monoclonal gammopathy of undetermined significance (MGUS) to multiple myeloma. Three basic goals of the methods used to investigate M proteins are detection, immunochemical characterization, and quantification. Serum protein electrophoresis (SPE) techniques have undergo...
متن کاملNested polymerase chain reaction amplification and sequencing analysis of the light-chain and heavy-chain variable regions in the influenza A H1N1 virus hemagglutinin monoclonal antibody gene.
The nested polymerase chain reaction (PCR) method was used for the amplification of the influenza A H1N1 virus hemagglutinin monoclonal antibody light-chain and heavy-chain genes. Sequence analysis of the obtained genes was then used to identify common cloning methods of the mouse immunoglobulin-kappa (Igκ) light-chain and heavy-chain variable gene regions. Twenty-two pairs of amplification pri...
متن کاملHeavy and Light Chain Allotypic Markers on Rabbit Homocytotropic Antibody
Evidence has been presented that rabbit homocytotropic antibody prepared against ovalbumin bears allotypic markers of both group a (heavy chain) and group b (light chain). This was shown by specific removal of activity in passive cutaneous anaphylaxis assays by anti-allotype immunoadsorbents. The homocytotropic antibody has properties which indicate that it belongs to a new class of rabbit immu...
متن کاملMonoclonal Antibody Charge Heterogeneity Analysis by Capillary Isoelectric Focusing on the Agilent 7100 Capillary Electrophoresis System
Due to the importance of monoclonal antibodies (mAb) as therapeutic agents, there is a growing demand for high resolution analytical methods to characterize these complex molecules. One important property of an mAb is its charge state that may change during and after manufacturing. A very useful technique to measure mAb charge heterogeneity is capillary isoelectric focusing (cIEF). This Applica...
متن کاملImmunoglobulin heavy chain/light chain pairs (HLC, Hevylite™) assays for diagnosing and monitoring monoclonal gammopathies.
Immunofixation (IFE) is a standard method for detecting monoclonal immunoglobulins and characterizing its isotype. Recently clonality can also be determined by using immunoglobulin (Ig) heavy chain/light chain immunoassays - HLC, HevyliteTM. HLC separately measures in pairs light chain types of each intact Ig class generating ratios of monoclonal Ig/uninvolved polyclonal Ig concentrations. Stud...
