Lhcb4 | CP29 chlorophyll a/b binding protein of plant PSII

Lhcb4 (CP29) is one of the 3 minor chlrorophyll a/b-binding proteins associated with Photosystem II in plants and algae. Lhcb4 has been suggested to act in the regulation of the chl a excited state concentration of PSII because of its ability of sensing lumenal pH resulting in reversible phosphorylation. In Arabidopsis thaliana 2 genes code for two isoforms Lhcb4.1 and Lhcb4.2. A third isoform (Lhcb4.3, At2g40100), probably only present in dicots, has found to be differently regulated and therefore has been denoted as Lhcb8.

BSA-conjugated synthetic peptide derived from a highly conserved sequence of Lhb4 proteins from angiosperms (monocots and dicots) and gymnosperms, including Arabidopsis thaliana (Lhcb4.1 At5g01530 and Lhcb4.2 At3g08940).

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.
