  • General notes

    Ab251607 is the carrier-free version of ab237721. This format is designed for use in antibody labeling, including fluorochromes, metal isotopes, oligonucleotides, enzymes.

     

    Our carrier-free formats are supplied in a buffer free of BSA, sodium azide and glycerol for higher conjugation efficiency.

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

    ab251607 is compatible with the Maxpar® Antibody Labeling Kit from Fluidigm.

    The Life Science industry has been in the grips of a reproducibility crisis for a number of years. Abcam is leading the way in addressing the problem with our range of recombinant monoclonal antibodies and knockout edited cell lines for gold-standard validation.

    One factor contributing to the crisis is the use of antibodies that are not suitable. This can lead to misleading results and the use of incorrect data informing project assumptions and direction. To help address this challenge, we have introduced an application and species grid on our primary antibody datasheets to make it easy to simplify identification of the right antibody for your needs.

    Immunohistochemical analysis of paraffin-embedded human tonsil tissue labeling CD3 epsilon with ab237721 at 1/2000 dilution, followed by ready to use Rabbit specific IHC polymer detection kit HRP/DAB (ab209101). Positive staining on the T lymphocytes in the human tonsil. The section was incubated with ab237721 for 30 mins at room temperature. The immunostaining was performed on a Leica Biosystems BOND® RX instrument. Counterstained with hematoxylin. Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is ready to use Rabbit specific IHC polymer detection kit HRP/DAB (ab209101). Heat mediated antigen retrieval with sodium citrate buffer (pH 6.0, epitope retrieval solution 1) for 20 mins.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS and sodium azide (ab237721).

    Flow cytometric analysis of 2% paraformaldehyde-fixed, 0.1% Tween-20 permeabilized mouse splenocytes labeling CD3 epsilon with ab237721 at 1/500 (right panel) compared with a Rabbit monoclonal IgG (ab172730) (left panel). Goat anti rabbit IgG (Alexa Fluor® 488, ab150077), at 1/2000 dilution was used as the secondary antibody.

    Cells were surface stained with anti-CD3 conjugated to Alexa Fluor® 647. Then fixed with 2% PFA for 10min and intracellularly stained with rabbit IgG (Left) or ab237721 (Right). They recognize the same cell population.
