AMSBIO have launched a comprehensive range of cytosections that offer a verified, reproducible and renewable source of positive/negative controls where the expression of the target biomarker is confirmed for accuracy and specificity by an immunoassay.

Researchers, antibody and assay developers as well as Immunohistochemistry (IHC) labs often find it difficult to find a reliable and verified source of positive / negative controls for their IHC experiments. This is especially important when they are developing new IHC protocols for novel targets whose expression pattern is not known or screening for new antibodies whose staining characteristics in IHC is unknown.

The new cytosections range from AMSBIO is comprised of high quality FFPE sections of cell pellets of over-expressing targeted biomarkers. The expression of target biomarkers in these cytosections is carefully verified for accuracy and specificity using Western Blot. Positive controls (cells transfected with the target protein) and negative controls (mock transfected cells) are available for genome wide human and mouse genome targets. In addition to its standard range - AMSBIO also offers a custom cytosections service where cell pellet composition and density can be designed according to customer’s needs.

Cytosection controls from AMSBIO provide the perfect tool for independently controlling and monitoring the performance of IHC protocols, run alongside your samples. Used to screen and set standards for sensitivity and specificity of your antibodies across different lots - these cytosections usefully provide a common standard and reference point for multi-center clinical trials. They also can be used to develop custom multiplex assays for sensitivity and specificity.

AntibodiesAntibodies are used in techniques such as confocal and fluorescence microscopy, flow cytometry, ELISA, ELISPOT, immunohistochemistry, western blotting and immunopreciptation. Select specific antigen reactivity, high specific affinity, low non-specific binding, monoclonal or polyclonal, primary or secondary antibodies and associated conjugates such as an enzyme or dye for visualization.ImmunologyImmunological techniques measure and characterize immune responses. Immunology kits and analysis systems often use techniques such as ELISA, radioimmunoassay (RIA) and immunodiffusion assays, Immunohistochemistry, and flow cytometry. Immunologists use equipment such as flow Cytometers, plate readers, plate washers and fluorescent microscopes.ImmunohistochemistryImmunohistochemistry (IHC) is a technique used to detect specific proteins in tissue samples by using antibodies that bind to target antigens. IHC is widely applied in pathology, immunology, hematology and cancer diagnostics.
