General notes
ab227116 is the carrier-free version of ab76024.
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 RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.
Rat: We have preliminary internal testing data to indicate this antibody may not react with this species. Please contact us for more information.

Target

Function
Occurs in almost all aerobically respiring organisms and serves to protect cells from the toxic effects of hydrogen peroxide. Promotes growth of cells including T-cells, B-cells, myeloid leukemia cells, melanoma cells, mastocytoma cells and normal and transformed fibroblast cells. -
Involvement in disease
Defects in CAT are the cause of acatalasia (ACATLAS) [MIM:115500]; also known as acatalasemia. This disease is characterized by absence of catalase activity in red cells and is often associated with ulcerating oral lesions. -
Sequence similarities
Belongs to the catalase family. -
Post-translational
modificationsThe N-terminus is blocked. -

All lanes : Anti-Catalase antibody [EP1929Y] - Peroxisome Marker (ab76024) at 1/10000 dilution
Lane 1 : Wild-type HeLa cell lysate
Lane 2 : CAT knockout HeLa cell lysate
Lysates/proteins at 20 µg per lane.
Performed under reducing conditions.
Predicted band size: 60 kDa
Observed band size: 60 kDaThis data was developed using the same antibody clone in a different buffer formulation (ab76024).
Lanes 1-2: Merged signal (red and green). Green - ab76024 observed at 60 kDa. Red - loading control ab8245 observed at 37 kDa.
ab76024 Anti-Catalase antibody [EP1929Y] - Peroxisome Marker was shown to specifically react with Catalase in wild-type HeLa cells. Loss of signal was observed when knockout cell line ab265250 (knockout cell lysate ab256859) was used. Wild-type and Catalase knockout samples were subjected to SDS-PAGE. ab76024 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at 1 in 10000 and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and 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.

Predicted band size: 60 kDaThis WB data was generated using the same anti-Catalase antibody clone, EP1929Y, in a different buffer formulation (cat# ab76024).
Lanes 1 - 3: Merged signal (red and green). Green - ab76024 observed at 60 kDa. Red - loading control, ab9484, observed at 37 kDa.
ab76024 was shown to specifically react with CAT when CAT knockout samples were used. Wild-type and CAT knockout samples were subjected to SDS-PAGE. Ab76024 and ab9484 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 1/5000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.
