Aiolos Monoclonal Antibody (8B2), eFluor™ 660, eBioscience™, Invitrogen™

Beschreibung

This gene encodes a member of the Ikaros family of zinc-finger proteins. Three members of this protein family (Ikaros, Aiolos and Helios) are hematopoietic-specific transcription factors involved in the regulation of lymphocyte development. This gene product is a transcription factor that is important in the regulation of B lymphocyte proliferation and differentiation. Both Ikaros and Aiolos can participate in chromatin remodeling. Regulation of gene expression in B lymphocytes by Aiolos is complex as it appears to require the sequential formation of Ikaros homodimers, Ikaros/Aiolos heterodimers, and Aiolos homodimers. At least six alternative transcripts encoding different isoforms have been described.

Description: This 8B2 monoclonal antibody reacts with mouse Aiolos, a 58-kDa member of the Ikaros family of zinc finger transcription factors. Expression of Aiolos is restricted to the lymphoid lineage, with B cells exhibiting the highest levels of expression, followed by NK and T cells. Studies demonstrate that Aiolos forms homodimers or heterodimerizes with Ikaros proteins. Moreover, Aiolos exhibits tyrosine phosphorylation and nuclear localization in response to IL-2 stimulation in T cells. Aiolos plays a role in IL-2-mediated anti-apoptosis by controlling Bcl-2 expression. Finally, Aiolos is involved in B cell development, with upregulation of this transcription factor observed at the pre-BI to pre-BII transition in response to pre-B cell receptor signaling.Applications Reported: This 8B2 antibody has been reported for use in intracellular staining followed by flow cytometric analysis.Applications Tested: This 8B2 antibody has been tested by intracellular staining and flow cytometric analysis of mouse splenocytes using the Foxp3/Transcription Factor Staining Buffer Set (cat. 00-5523) and protocol. This can be used at less than or equal to 1 μg per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.eFluor™ 660 is a replacement for Alexa Fluor™ 647. eFluor™ 660 emits at 659 nm and is excited with the red laser (633 nm). Please make sure that your instrument is capable of detecting this fluorochome.Excitation: 633-647 nm; Emission: 668 nm; Laser: Red Laser.Filtration: 0.2μm post-manufacturing filtered.
