Product Information
Immunogen
Purified ferritin from dried peas, Pisum sativum L. After extraction from pea flour, the ferritin was further purified by gel filtration chromatography to >95% purity as estimated from a Coomassie-stained gel.
Antibody is most likely to bind to all ferritin isoforms from pea however it has not been confirmed as yet.

Host
Rabbit
Clonality
Polyclonal
Purity
Immunogen affinity purified serum in PBS pH 7.4.
Format
Lyophilized
Quantity

Application examples
Application examples
Molecular weight markers (1); purified ferritin from Pisum sativum, 5 ng (2) and 0.5 ng (3); 5 µg of Pisum sativum total cell extract (4) ; 5 µg Arabidopsis thaliana total leaf extract (5). Proteins were separated on a 12% SDS-PAGE gel and transferred to nitrocellulose membrane using a semi-dry blotting apparatus. Blots were blocked in TBS, 0.1% (v/v) Tween-20, 5% (w/v) skimmed dried milk (TBS-TM) for 1 hour at RT. The antiserum was diluted 1: 5,000 in TBS-TM and incubated with the blot for 2 hours at RT. The blot was washed 3 times for 10 min with TBS-TM, then incubated with secondary antibodies anti-rabbit IgG HRP diluted to 1: 5000 in TBS-T for 1 hour. The blot was washed 4 times with TBS-T and developed with chemiluminescent detection reagent.

Additional information
Note, the calculated molecular weight of pea ferritin is 28 kDa. Removal of the N-terminal targeting sequence upon protein import into plastids results in a protein with an apparent mol weight of ~23 kDa.
This antibody is also recognizing horse ferritin (above 100 ng in Western blot).
Background
Background
Ferritin forms a 24-subunit cage for storage of mineral iron. In plants, ferritin is predominantly localized in the plastids, and its expression is upregulated in response to iron or oxidative stress.
