Armenian Hamster IgG Isotype Control (eBio299Arm), eFluor™ 506, eBioscience™, Invitrogen™

Description

Description: The eBio299Arm monoclonal antibody is useful as an isotype control immunoglobulin. Applications Reported: This eBio299Arm antibody has been reported for use in flow cytometric analysis. Applications Tested: This eBio299Arm antibody has been tested by flow cytometric analysis of normal human peripheral blood cells and mouse splenocytes. Use the isotype control at the same concentration as the experimental antibody. eFluor® 506 can be excited with the violet laser line (405 nm) and emits at 506 nm. We recommend using a 510/20 band pass filter, or equivalent. Please make sure that your instrument is capable of detecting this fluorochrome. Excitation: 405 nm; Emission: 506 nm; Laser: Violet Laser. Filtration: 0.2 μm post-manufacturing filtered.

The isotype of a primary antibody and the application it is being used in can result in background staining. Primary antibody background noise can be caused by binding to Fc receptors on target cells; by non-specific interactions with cellular proteins, carbohydrates, and lipids; or by cell autofluorescence. Isotype 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 (ChIP), immunohistochemistry, and gel shifts. Isotype controls should match with the primary antibody species and isotype so that the level of specific staining by the primary antibody may be accurately determined. If using directly labeled primary antibodies, the isotype control works best if conjugated with the same label as the test antibody.
