Background Information

Catalase belongs to the catalase family. CAT occurs in almost all aerobically respiring organisms and serves to protect cells from the toxic effects of hydrogen peroxide. CAT promotes growth of cells including T-cells, B-cells, myeloid leukemia cells, melanoma cells, mastocytoma cells and normal and transformed fibroblast cells. CAT catalyzes the reaction: 2 H2O2 = O2 + 2 H2O. Defects in CAT are the cause of acatalasia (ACATLAS) which also known as acatalasemia.

Silvia (Verified Customer) (08-11-2022)

It worked well for western blotting.

  • Applications: Western Blot
  • Primary Antibody Dilution: 1:2000
  • Cell Tissue Type: Human fibroblasts

Maximilian (Verified Customer) (06-03-2022)

The antibody works fine and detected human catalase at 0.01 and 0.05 µg total protein amount in my blot. Accidental storage time of 24h at RT did not affect performance.

  • Applications: Western Blot
  • Primary Antibody Dilution: 1:2000
  • Cell Tissue Type: HepG2

Maximilian (Verified Customer) (05-27-2022)

Antibody performed well in detection of catalase standard protein (catalase from human erythrocytes) but signal for cell lysates could be better (will increase antibody concentration). Maybe this is due to the storage for 24h at room temperature, which was the result of wrong storage by a colleague, as the package was erroneously delivered to her instead of me.

  • Applications: Western Blot
  • Primary Antibody Dilution: 1:2000
  • Cell Tissue Type: HepG2

Tom (Verified Customer) (08-25-2021)

Membrane blocked in BSA solution prior to incubation with antibody (1:2000). Correct band is clearly visible, but with some background.
