Flow isotype control
WebIsotype control antibodies can act as negative controls to help differentiate non-specific background signal from specific antibody signal because they have no relevant specificity to a target antigen. While isotype controls are most commonly used in flow cytometry, they are useful in other applications such as chromatin immunoprecipitation ... WebIsotype controls are conjugated antibodies that lack specificity to the target which can be used as negative controls to estimate the level of staining background and non-specific …

WebIsotype control antibodies match the host species and class of the test antibody but are generated against irrelevant antigens not present in cells or samples of interest, and are therefore useful for characterizing …
WebOct 12, 2016 · Isotype Controls May Not Be Appropriate Gating Controls To exemplify the potential problem with using isotype controls to place gates and define background signal in flow cytometry, we compared binding of anti-Tie2 AF647 and IgG1 AF647 to healthy donor CD14 + monocytes. WebApr 4, 2024 · Objectives: To evaluate clinicopathologic characteristics of biclonal chronic lymphocytic leukemia (CLL). Methods: Retrospectively analyze clinical data and pathologic features. Results: Ten cases were identified in which flow cytometry demonstrated an abnormal B-cell population with a CLL-like immunophenotype but showed no definitive …
WebFc Blocking. Flow cytometry utilizes fluorescently labeled antibodies to bind and identify specific cellular subsets. The specificity of the binding relies on the unique variable regions of each antibody clone. In contrast, it is the common Fc part of the antibody molecules that interacts with a plethora of immune cells (such as B lymphocytes ...
