Catalog No. ABIN7656452

The Mouse Monoclonal anti-MHC Class II antibody has been validated for FACS, IHC and IHC (fp). It is suitable to detect MHC Class II in samples from Human.

Quick Overview for MHC Class II antibody (CF®740) (ABIN7656452)

Target: MHC Class II (MHC2) (Major Histocompatibility Complex Class II Antigen (MHC2))

Reactivity: Human

Host: Mouse

Clonality: Monoclonal

Conjugate: This MHC Class II antibody is conjugated to CF®740

Application: Flow Cytometry (FACS), Immunohistochemistry (IHC), Immunohistochemistry (Formalin-fixed Paraffin-embedded Sections) (IHC (fp))

Clone: 19-26-1

Product Details anti-MHC Class II Antibody (CF®740)

Purpose: MHC II (HLA-DRA)(19-26.1), CF740 conjugate

Characteristics: This MAb reacts with the HLA-DR antigen, a member of MHC class II molecules. It does not cross react with HLA-DP and HLA-DQ. HLA-DR is a heterodimeric cell surface glycoprotein comprised of a 36 kDa alpha (heavy) chain and a 28 kDa beta (light) chain. It is expressed on B-cells, activated T-cells, monocytes/macrophages, dendritic cells and other non-professional APCs. In conjunction with the CD3/TCR complex and CD4 Molecules, HLA-DR is critical for efficient peptide presentation to CD4 T cells. It is an excellent histiocytic marker in paraffin sections producing intense cytoplasmic staining. True histiocytic neoplasms are similarly positive. HLA-DR antigens also occur on a variety of epithelial cells and their corresponding neoplastic counterparts.Primary antibodies are available purified, or with a selection of fluorescent CF® Dyes and other labels. CF® Dyes offer exceptional brightness and photostability. Note: Conjugates of blue fluorescent dyes like CF®405S and CF®405M are not recommended for detecting low abundance targets, because blue dyes have lower fluorescence and can give higher non-specific background than other dye colors.

Immunogen: Raji cells

Isotype: IgG2a, kappa

Application Details

Application Notes: Higher concentration may be required for direct detection using primary antibody conjugates than for indirect detection with secondary antibody. Immunofluorescence: 0.5-1 μg/mL. Immunohistology formalin-fixed 1-2 μg/mL. Staining of formalin-fixed tissues is enhanced by boiling tissue sections in 10 mM citrate buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 minutes. Flow Cytometry 0.5-1 μg/million cells/0.1 mL. Optimal dilution for a specific application should be determined by user
