R-phycoerythrin (R-PE)
Monoclonal Antibody
Share |


Prod. No.:H134
Clone:L243
Pkg. Size:50 µg, 100 µg, 200 µg
Description
Specificity:
Anti-Human HLA-DR recognizes the HLA-DR class II major histocompatibility antigen. HLA-DR is a transmembrane glycoprotein composed of alpha and beta subunits with molecular weights of 36 kDa and 27 kDa, respectively.1 Anti HLA-DR (Clone L243) reacts with a monomorphic determinant and does not cross react with HLA-DQ or HLA-DP.2

Antigen Distribution:
The HLA-DR antigen is present on B-lymphocytes, activated T-lymphocytes and activated natural killer (NK) lymphocytes. This antigen is also expressed on monocytes, macrophages, human progenitor cells and B-cell lymphomas.

Reporter Molecule:
R-phycoerythrin (R-PE) has a molecular weight of 240 kDa and is purified from red algae. R-PE is an intensely bright phycobiliprotein with an absorption maxima at approximately 496, 546 and 565 nm, and a fluorescence emission maximum of ~578 nm.

Host Species
Mouse
Formulation
This R-phycoerythrin (R-PE) conjugate is formulated in 0.01 M phosphate buffered saline (PBS) pH 7.4, 1% BSA and 0.09% sodium azide as a preservative.
