  • General notes

    ab267394 is the carrier-free version of ab245235.

    Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. The carrier-free buffer and high concentration allow for increased conjugation efficiency.

    This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.

    Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with

    This product is compatible with the Maxpar® Antibody Labeling Kit from Fluidigm, without the need for antibody preparation. Maxpar® is a trademark of Fluidigm Canada Inc.

    This product is a recombinant monoclonal antibody, which offers several advantages including:

    • - High batch-to-batch consistency and reproducibility
    • - Improved sensitivity and specificity
    • - Long-term security of supply
    • - Animal-free production

    Immunohistochemical analysis of paraffin-embedded mouse spleen tissue labeling CD19 with ab245235 at 1/1000 dilution (0.446 µg/ml) followed by a ready to use Goat Anti-Rabbit IgG H&L (HRP Polymer). Positive staining on mouse spleen (PMID: 18648532). The section was incubated with ab245235 for 10 mins at room temperature. The immunostaining staining was performed on a Leica Biosystems BOND® RX instrument. Counterstained with hematoxylin.

    Secondary antibody only control: Secondary antibody is a ready to use Goat Anti-Rabbit IgG H&L (HRP Polymer).

    Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution 2) for 20 mins.

    Blocking and dilution buffer and concentration: 5% NFDM/TBST.

    Exposure time: 30 seconds.

    Flow cytometric analysis of mouse peripheral blood mononuclear cell (PBMC) cells labeling CD19 with ab245235 at 1/500 dilution (Right) compared with a Rabbit monoclonal IgG (ab172730) isotype control (Left). Goat anti rabbit IgG (Alexa Fluor® 488, ab150077) at 1/2000 dilution was used as the secondary antibody.

    Cells were stained with rabbit IgG (Left) or ab245235 (Right). Then stained with anti-CD3 conjugated to Alexa Fluor® 647. CD19 and CD3 are mutually exclusive expressed in mouse PBMC.

    Gated on viable cells.
