It binds CD48 to modulate cytotoxicity, cytokine secretion, and immune synapse formation. Signal polarity (activating vs. inhibitory) depends on adaptor usage, including SAP\/SH2D1A and EAT-2, enabling context-specific tuning of effector function. The \u0026lt;b\u0026gt;CD244 antibody\u0026lt;\/b\u0026gt; helps delineate these pathways by resolving expression and activation states across cell subsets.\u0026lt;p\u0026gt;Dysregulated CD244 signaling is linked to impaired NK function in chronic viral infection, T cell exhaustion in tumors, and altered myeloid responses. Expression level, phosphorylation status, and adaptor association serve as readouts for immune competence in immuno-oncology, vaccine studies, and autoimmunity research, making precise detection with the CD244 antibody valuable for mechanistic and translational investigations.\u0026lt;p\u0026gt;The CD244 antibody supports applications such as flow cytometry, immunohistochemistry, and western blot to quantify receptor abundance, track subcellular localization, and assess pathway modulation under genetic or pharmacologic perturbation. With high specificity and reproducible performance across primary cells and model systems, the CD244 antibody enables rigorous analysis of NK and T cell biology.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable style=\"width:100%; border-collapse:collapse;\"\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eFamily\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003ePrimary antibody\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eFormulation\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003e0.5mg\/ml if reconstituted with 0.2ml sterile DI water\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eFormat\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eAntigen affinity purified\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eHost Animal\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eRabbit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eClonality\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003ePolyclonal (rabbit origin)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eIsotype\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eRabbit IgG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eSpecies Reactivity\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eMouse, Rat\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eApplication\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eWB, IHC-P, Direct ELISA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eApplication Details\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eWestern blot: 0.5-1 ug\/ml,Immunohistochemistry (FFPE): 2-5ug\/ml,Direct ELISA: 0.1-0.5ug\/ml\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eApplication Note\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eOptimal dilution of the Cd244 antibody should be determined by the researcher.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eLocalization\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eCell membrane\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eImmunogen\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eRecombinant mouse protein (amino acids Q20-N374) was used as the immunogen for the Cd244 antibody.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eBuffer\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eLyophilized from 1X PBS with 2% Trehalose\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003ePurity\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eAntigen affinity purified\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left; vertical-align:top; padding:6px; border-bottom:1px solid #eee;\"\u003eStorage\u003c\/th\u003e\n\u003ctd style=\"padding:6px; border-bottom:1px solid #eee;\"\u003eAfter reconstitution, the Cd244 antibody can be stored for up to one month at 4oC.
