Notes

ab223546 is the carrier-free version of Anti-CD40 antibody [EPR20540] ab213205.

Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

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 1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.

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.

Our Low endotoxin, azide-free formats have low endotoxin level (1 EU/mg, determined by the TAL assay) and are free from azide, to achieve consistent experimental results in functional assays.

Product promise

    This data was developed using the same antibody clone in a different buffer formulation (Anti-CD40 antibody [EPR20540] ab213205).

    Lanes 1 - 3: Merged signal (red and green). Green - Anti-CD40 antibody [EPR20540] ab213205 observed at 42 kDa. Red - loading control, Anti-alpha Tubulin antibody [DM1A] - Loading Control ab7291 (Mouse anti-Alpha Tubulin [DM1A] observed at 55kDa.

    Anti-CD40 antibody [EPR20540] ab213205 was shown to react with CD40 in U-2 OS wild-type cells in Western blot. Loss of signal was observed when CD40 knockout sample was used. U-2 OS wild-type and CD40 knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in 3% Milk in TBS-T (0.1% Tween®) before incubation with Anti-CD40 antibody [EPR20540] ab213205 and Anti-alpha Tubulin antibody [DM1A] - Loading Control ab7291 (Mouse anti-Alpha Tubulin [DM1A] overnight at 4°C at a 1 in 2000 dilution and a 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed (Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

    Mass Cytometry - Anti-CD40 antibody [EPR20540] - Low endotoxin, Azide free (ab223546)

    Imaging Mass Cytometry™ (IMC™) image of human tonsil tissue stained with Anti-CD40 antibody [EPR20540]. ab223546 (carrier-free antibody, purified) was metal-conjugated using a Maxpar® Antibody Labeling Kit from Fluidigm. Immunostaining was performed according to Fluidigm’s protocols. Briefly, slides were subject to deparaffinization and heat-induced epitope retrieval, followed by overnight incubation at 4°C with an antibody cocktail containing metal-tagged antibodies in blocking buffer. Slides were subsequently washed with 0.2% Triton-X and 1x PBS, counterstained with Cell-ID™ Intercalator-Ir diluted at 1/400 in 1x PBS for 30 min at room temperature, rinsed for 5 min with distilled H2O, and air-dried prior to IMC™ acquisition. IMC™ acquisition was performed using the Fluidigm Hyperion™ Imaging System.
