L-Ascorbate Peroxidase (APX) Antikörper

Antigen: L-Ascorbate Peroxidase (APX)

Klonalität: Polyklonal

Wirt: Kaninchen

Reaktivität: Arabidopsis thaliana

Applikation: Western Blot (WB)

Produktnummer: ABIN334581

Produktbeschreibung

Immunogen: synthetic peptide derived from Arabidopsis thaliana tAPX (acession At1g77490)and sAPX (At4g08390) protein sequences, coupled to BSA. Five out of twelveamino acids are also identical with cAPX1 (At1g07890), cPX2 (At3g09640) andpAPX (At4g35000)

Format: Lyophilized

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

Spezifität: Predicted reactivity: N. tabacum thylakoid-bound APX, stromal APX, O.sativa probable L-ascorbateperoxidase 6 chloroplastic, S. lycopersicum thylakoid-bound APX, S. oleraceastromal APX, thylakoid-bound.

Anwendungen

Applikationshinweise: Recommended Dilution 1: 2000 with standard ECL (WB).

Reinheit: Serum

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

Forschungsgebiet: Pflanzenphysiologie

Beschränkungen: Nur für Forschungszwecke einsetzbar

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. ABIN334581 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.
