Application examples

application information

10 µg of total leaf protein from P.sativum (1) was separated on 4-12% NuPage (Invitrogen) and blotted on nitrocellulose. Molecular marker was MagicMark (Invitrogen). Filters where blocked overnight in TBST containing 5 % milkpowder and incubated with 1:1000 anti-CSP41b antibody (AS08 298, 1h). After incubation with 1:10000 secondary HRP coupled anti-rabbit antibody (1h) signals were visualized with standard ECL (GE Healthcare).

CSP41b (CRB, RAP38 ortholog, gb5f) is a chloroplast stem-loop-binding, ribosome-associated endonuclease. This protein is involved in 23S rRNA metabolism and highly conserved in photosynthetic organisms including angio- and gymnosperms, green algae, and cyanobacteria.
