product information

Ascorbate peroxidase (APX) is the enzyme catalyzing the ascorbate-dependent reduction of hydrogen peroxide. Ascorbate (AA) plays a key role in defense against oxidative stress and is particularly abundant in fruits and photosynthetic tissues. AA is found in every compartment of the plant cell including the apoplast.


KLH-conjugated peptide derived from N-terminal of Zea mays cytosolic APX Q41772

Host Rabbit
Clonality Polyclonal
Purity Total IgG
Format Lyophilized in PBS pH 7.4
Quantity 200 ĩl
Reconstitution For reconstitution add 200 ĩl of sterile water.

store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please, remember to spin tubes briefly prior to opening them to avoid any losses that might occur from lyophilized material adhering to the cap or sides of the tubes.

Tested applications western blot (WB), immunoprecipitation (IP), immunolocalization (IL)
