HLA DR antibody | YD1/63.4.10
Rat anti Human HLA-DR antibody, clone YD1/63.4.10 used for the evaluation of MHC class II expression on human PBMC by flow cytometry.
Image caption:
Plasmacytoid dendritic cells show weak T cell stimulatory capacity. A: Flow cytometric analysis of human PBMC and DC. pDC are characterized as lineage− CD11c− CD303+ cells (middle panel). Dot plots (right side) exemplarily depicts isolated pDC, percentage indicates purity. Histograms show surface expression of CD40, CD80, CD86, CD58 and HLA-DR on resting and CpG/IL-3-activated pDC and cytokine cocktail activated cDC. Isotype-matched control mAb staining is shown in grey. One representative result of three independent experiments is shown.

Rat anti Human HLA DR antibody, clone YD1/63.4.10 recognizes a monomorphic determinant of human HLA DR which is an MHC class II cell surface receptor expressed primarily on antigen presenting cells such as B lymphocytes, monocytes, macrophages and activated T lymphocytes.
The major histocompatibility complex (MHC) is a cluster of genes that are important in the immune response to infections. In humans, this complex is referred to as the human leukocyte antigen (HLA) region. There are 3 major MHC class II proteins encoded by the HLA which are HLA DP, HLA DQ and HLA DR.
