  • General notes

    ab274427 is the carrier-free version of a274418.

    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
