• Host: Rabbit
• Reactivity: Human, Mouse
• Clonality: Polyclonal
• Specificity: CD28 (Phospho-Tyr218) Antibody detects endogenous levels of CD28 only when phosphorylated at Tyr218.
• Purity/Purification: Purified from rabbit antiserum by affinity-chromatography using phospho peptide. The antibody against non-phospho peptide was removed by chromatography using corresponding non-phospho peptide.
• Form/Format: Rabbit IgG in phosphate buffered saline (Phospho-without Mg2+ and Ca2+), pH 7.4, 150mM NaCl, 0.02% sodium azide and 50% glycerol.
• Concentration: 1 mg/ml (varies by lot)
• Sequence Length: 234

• Applicable Applications for anti-CD28 antibody: Western Blot (WB), ELISA (EIA)
• Application Notes: WB: 1:500~1:1000; ELISA: 1:10000
• Target Modification: Phospho
• Modification Sites: H:Y218; M:Y216
• Immunogen: The antiserum was produced against synthesized phospho-peptide derived from human CD28 around the phosphorylation site of Tyr218.
• Preparation and Storage: Stable at -20 degree C for at least 1 year.

NCBI Description

The protein encoded by this gene is essential for T-cell proliferation and survival, cytokine production, and T-helper type-2 development. Several alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jul 2011]

Uniprot Description

Involved in T-cell activation, the induction of cell proliferation and cytokine production and promotion of T-cell survival. Enhances the production of IL4 and IL10 in T-cells in conjunction with TCR/CD3 ligation and CD40L costimulation (PubMed:8617933). Isoform 3 enhances CD40L-mediated activation of NF-kappa-B and kinases MAPK8 and PAK2 in T-cells (PubMed:15067037).
