This antibody has been characterized as a superagonist (5)\u003c\/p\u003e\n\n  \u003cp\u003eHuman CD28 is an important costimulatory molecule found on all CD4+ T cells and on about half of the CD8+ T cells. T cell activities attributed to CD28 include prevention of anergy, induction of cytokine gene transcription, stabilization of cytokine mRNA and activation of CD8+ cytotoxic T lymphocytes.  the ligands for CD28 identified as CD80(B7-1) and CD86(B7-2), are immunglobulin superfamily monomeric transmembrane glycoproteins of 60 kd and 80 kd respectively. Anti-CD28 antibodies have been shown to have a strong adjuvant effect when conjugated to an immunogen (4). Monovalency of the CD28 receptor for its natural ligands is essential to provide costimulation without inducing responses in the absense of TCR engagement (7).\u003c\/p\u003e\n\n  \u003ch2\u003eValidated Applications\u003c\/h2\u003e\n  \u003ctable class=\"bhp-spec-table\"\u003e\n    \u003ctr\u003e\n\u003cth\u003eApplication\u003c\/th\u003e\n\u003cth\u003eRecommended Dilution\u003c\/th\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eFlow Cytometry (FC)\u003c\/td\u003e\n\u003ctd\u003eSee datasheet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEIA\u003c\/td\u003e\n\u003ctd\u003eSee datasheet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAgonist\u003c\/td\u003e\n\u003ctd\u003eSee datasheet\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\n  \u003ch2\u003eProduct Specifications\u003c\/h2\u003e\n  \u003ctable class=\"bhp-spec-table\"\u003e\n    \u003ctr\u003e\n\u003cth\u003eClone\u003c\/th\u003e\n\u003ctd\u003eANC28.1\/5D10\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eClonality\u003c\/th\u003e\n\u003ctd\u003eMonoclonal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHost Species\u003c\/th\u003e\n\u003ctd\u003eMouse\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eIsotype\u003c\/th\u003e\n\u003ctd\u003eIgG1 kappaappa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecies Reactivity\u003c\/th\u003e\n\u003ctd\u003eHuman\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConjugate\u003c\/th\u003e\n\u003ctd\u003eBiotin, FITC, PE, Unconjugated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStorage\u003c\/th\u003e\n\u003ctd\u003eStore at 2 - 5°C.
