Description: The monoclonal antibody eBio4E5 (4E5) reacts with Ly-49D, an activating member of the Ly-49 family of NK cell receptors. This family of receptors form homodimers that recognize MHC Class I molecules. The activating Ly-49 receptors (Ly-49D and Ly-49H) do not contain immune receptor tyrosine-based inhibitory motifs (ITIM) in their cytoplasmic domains, distinguishing them from the inhibitory Ly-49 family members. Instead, activating Ly-49 molecules have been shown to associate with DAP12 which contains an immunoreceptor tyrosine-based activation motif (ITAM) that is required for positive signaling. Expression of different Ly-49 family members is not linked, therefore, several Ly-49 proteins can be expressed on the same cells. Expression of Ly-49D on subsets of NK cells is strain-dependent and is found in C57BL/6, CB6F1 and SJL mice, while BALB/c, DBA/2, AKR and CBA/J mice are negative for Ly-49D. In 129/J mice, eBio4E5 also recognizes Ly-49O, Ly-49V and Ly-49R. eBio4E5 is reported to have functional (activating) activity.
Applications Reported: This eBio4E5 (4E5) antibody has been reported for use in flow cytometric analysis.
Applications Tested: This eBio4E5 (4E5) antibody has been tested by flow cytometric analysis of mouse splenocytes. This can be used at less than or equal to 0.5 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.
Filtration: 0.2 µm post-manufacturing filtered.
