The eBio13G3-19D monoclonal antibody reacts with mouse Ly108, the mouse homologue of human SLAMF6 (signaling lymphocyte activation molecule family member 6). Mouse Ly108 is also known as NTB-A (NK cell, T cell, B cell antigen), and is expressed on NK, T cells, and B cells. Engagement of the Ly108 receptor enhances NK cell activity and expression of IFN-gamma, and contributes to the inability of NK cells to kill Epstein Barr virus-infected B cells in X-linked lymphoproliferative disease. CD4+ T cells from Ly108 knock-out mice exhibit diminished ability to produce IL-4 and defective neutrophil functions.

Staining has not revealed any strain differences between C57BL/6 and BALB/c mice. Other strains have not been tested.

Applications Reported: This eBio13G3-19D (13G3-19D) antibody has been reported for use in flow cytometric analysis.

Applications Tested: This eBio13G3-19D (13G3-19D) antibody has been tested by flow cytometric analysis of mouse splenocytes and thymocytes. This can be used at less than or equal to 0.8 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.

Our internal testing shows that NovaFluor Yellow 755 non-specifically stains B cells in SJL mice. Non-specific staining has not been observed in BALB/c or C57BL/6 mice. Other strains have not been tested. See the Antibody Testing Data for an example of this strain-dependent difference.

NovaFluor dyes are not compatible with DNA intercalating viability dyes. Do not use viability dyes such as propidium iodide, 7-actinomycin D (7-AAD) and DAPI. Invitrogen LIVE/DEAD Fixable Dead Cell stains are recommended for use with NovaFluor dyes.

Each NovaFluor conjugate or kit is shipped with CellBlox Blocking Buffer. Use this buffer whenever staining with NovaFluor conjugates, including single-color compensation controls using cells. Whenever possible, we recommend adding CellBlox Blocking Buffer to antibody cocktails/master mixes prior to combining with cells. Add 5 µL per sample (regardless of the number of NovaFluors in your panel) to use the antibody cocktail as intended. For single-color controls, use 5 µL of CellBlox Blocking Buffer per 100µL of cell sample containing 10^3 to 10^8 cells.

NovaFluor conjugates are based on Phiton™ technology utilizing novel nucleic acid dye structures that allow for engineered fluorescent signatures with consideration for spillover and spread impacts. Learn more
