Purified native plastocyanin from Spinacia oleracea UniProt: P00289
Catalpa bungei, Dicots, Hordeum vulgare, Physcomitrella patens, Ricinus communis, Solanum lycopersicum
10 µg of total protein from Arabidopsis thaliana (1), Brassica juncea (2), Zea mays (3), Oryza sativa (4), Solamum lycopersicum (5), Nicotiana tabacum (6), Heliantus annuus (7) were separated on SDS-PAGE and blotted to nitrocellulose. Filters were probed with anti-PC antibody (AS06 141, 1:2000). Signal was developed using alkaline phosphatase conjugated secondary antibody. Each sample was run in duplicate. Signal was developed using alkaline conjugated secondary antibody.
Cellular [compartment marker] of chloroplast thylakoid lumen
This product can be sold containing ProClin if requested.
Plastocyanin runs abberant due to negative charge at 12-19 kDa on SDS-PAGE depending upon the system used. in 15 % gel the protein will run closer to its true MW than in 12 % gel. In some cases PC can be very acidic and run at twice of its MW.
PC1 runs closer to 14 kDa while PC2 runs closer to 19 kDa. For good resolution adding fresh DTT to the sample buffer is recommended.
PC2 is generally more abundant and it increases with Cu feeding. PC1 is expressed first after etiolated seedlings are placed in the light.
Plastocyanin (PC) is a small Cu protein and a mobile electron carrier in the lumen of the thylkoids. PC interacts with the B/F complex and Photosystem I. Alternative name: DNA-damage-repair/toleration protein DRT112.
