HLA DQ1/DQ3 Antibody (HL-37) [CoraFluor™ 1] Summary

• Description: CoraFluor(TM) 1 is a high performance terbium-based TR-FRET (Time-Resolved Fluorescence Resonance Energy Transfer) or TRF (Time-Resolved Fluorescence) donor for high throughput assay development. CoraFluor(TM) 1 absorbs UV light at approximately 340 nm, and emits at approximately 490 nm, 545 nm, 585 nm and 620 nm. It is compatible with common acceptor dyes that absorb at the emission wavelengths of CoraFluor(TM) 1. CoraFluor(TM) 1 can be used for the development of robust and scalable TR-FRET binding assays such as target engagement, ternary complex, protein-protein interaction and protein quantification assays.

• Immunogen: Burkitt's lymphoma cell line Raji
• Specificity: The antibody HL-37 reacts with polymorphic determinant on human HLA-DQ1 and HLA-DQ3 molecules (recognized epitope was found on isolated beta chain of DQ1), but does not react with HLA-DQ2. DQ is the isotype of human MHC Class II molecules expressed on antigen-presenting cells (APC; dendritic cells, B lymphocytes, monocytes, macrophages).
• Isotype: IgG3
• Clonality: Monoclonal
• Host: Mouse
• Gene: HLA-DQA1
• Purity: Protein A purified

Applications/Dilutions

• Dilutions:
  • CyTOF-ready

Background

HLA-DQB1 belongs to the HLA class II beta chain paralogues. This class II molecule is a heterodimer consisting of analpha (DQA) and a beta chain (DQB), both anchored in the membrane. It plays a central role in the immune system bypresenting peptides derived from extracellular proteins. Class II molecules are expressed in antigen presenting cells(APC: B lymphocytes, dendritic cells, macrophages). The beta chain is approximately 26-28 kDa and it contains 6 exons.Exon one encodes the leader peptide, exons 2 and 3 encode the two extracellular domains, exon 4 encodes thetransmembrane domain and exon 5 encodes the cytoplasmic tail. Within the DQ molecule both the alpha chain and the betachain contain the polymorphisms specifying the peptide binding specificities, resulting in up to 4 differentmolecules. Typing for these polymorphisms is routinely done for bone marrow transplantation. (provided by RefSeq)
