product information

APX plays a key role in plant antioxidant system by reducing hydrogen peroxide to water. Cellular localization includes chloroplast (tAPX and sAPX), cytosol (cAPX) and peroxisome (pAPX).


Synthetic peptide derived from Arabidopsis thaliana tAPX (acession At1g77490) and sAPX (At4g08390) protein sequences, coupled to BSA. Five out of twelve amino acids are also identical with cAPX1 (At1g07890), cPX2 (At3g09640) and pAPX (At4g35000)

Host Rabbit
Clonality Polyclonal
Purity Serum
Format Lyophilized
Quantity 200 µl
Reconstitution For reconstitution add 200 µl of sterile water.
Storage 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.

Application example


5 to 20 μg of total leaf protein from Arabidopsis thaliana (left panel) and chloroplast fractions (thylakoids and soluble, right panel) was separated on 15% polyacrylamide gel with 6M urea and blotted on PVDF. Filters were blocked 1h with 5% BSA, incubated with anti-APX antibody (1: 2000, 1h) followed by incubation with secondary HRP-coupled anti rabbit antibody (1: 10 000, 1h). Signal was detected with standard ECL. AS08 368 is reactive to thylakoid (tAPX, 38 kDa), stromal (sAPX, 33 kDa), peroxisomal (pAPX, 31 kDa) and cytoplasmic (cAPX1 + cAPX2, 25 kDa) forms of ascorbate peroxidases.
