product information

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.

KLH-conjugated synthetic peptide derived from CSP41b protein sequence of Arabidopsis thaliana Q9SA52

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.

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).
