Anti-CIITA antibody, Mouse monoclonal

Class II transactivator protein (CIITA) protein contains an acidic region in its N-terminal with transactivation activity, that binds to proteins in the basal transcription machinery and to cAMP response element-binding protein (CREB)-binding protein (CBP). The protein contains motifs for nuclear translocation, GTP binding motif and C-terminal leucine-rich repeats. CIITA is expressed constitutively in B lymphocytes and in immature dendritic cells, while in other cells its expression is induced by IFN-γ .

Monoclonal Anti-CIITA (mouse IgG1 isotype) is derived from the hybridoma 7-1H produced by the fusion of mouse myeloma cells (Sp20 cells) and splenocytes from BALB/c mice immunized with purified N-terminal recombinant CIITA, amino acids 1-350. CIITA is expressed constitutively in B lymphocytes and in immature dendritic cells, while in other cells its expression is induced by IFN-γ.

Monoclonal Anti-CIITA recognizes human1 and mouse † CIITA.

The antibody may be used in immunoblotting (∼130 kDa) and immunocytochemistry.

Class II transactivator protein (CIITA) interacts with specific transcription factors and creates the appropriate transcriptional scaffold required for HLA-D gene expression.

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
