Background
HLA-DR is used for the identification of human B cell and T cell subsets associated with approximately 10% of peripheral blood lymphocytes 28-34,000 M.W. surface antigen, and is present in low density on monocytes and macrophages.

Synonyms: HLA-DR*

Source

Immunogen: HLA-DR=Derived from the hybridization of mouse NS-1/1-Ag4 myeloma cells with spleen cells of BALB/c mice immunized with human lymphoblastoid B-cell line RPMI 8866

Product

Product Form: Unconjugated

Formulation: Provided as solution in phosphate buffered saline with 0.08% sodium azide

Purification Method: Protein A/G Chromatography

Concentration: See vial for concentration

Applications
PBMC: Add 10 µl of MAB/10^6 PBMC in 100 µl PBS. Mix gently and incubate for 15 minutes at 2º to 8ºC. Wash twice with PBS and analyze or fix with 0.5% v/v of paraformaldehyde in PBS and analyze. WHOLE BLOOD: Add10 µl of MAB/100 µl of whole blood. Mix gently and incubate for 15 minutes at room temperature 20ºC. Lyse the whole blood. Wash once with PBS and analyze or fix with 0.5% v/v of paraformaldehyde in PBS and analyze. See instrument manufacturer’s instructions for Lysed Whole Blood and Immunofluorescence analysis with a flow cytometer or microscope.
