product information

The major light-harvesting antenna complex II (LHCII) in photsynthetic eukaryotes is located in the thylakoid membrane of the chloroplast. It is a heterotrimeric complex formed by up to 3 different individual subtypes of chlorophyll a/b-binding proteins: Lhcb1, Lhcb2, and Lhcb3. While Lhcb1 and Lhcb2 are quite similar and regularily present in multiple gene-copies, the Lhcb3 protein differs in pigment-composition and molecular size and often is coded by only a single gene. Lhcb3 seems not to be present in the mobile LHCII trimers involved in state 1-state 2 transitions.

BSA-conjugated synthetic peptide derived from a highly conserved sequence of Lhcb3 proteins from angiosperms (monocots and dicots) and gymnosperms, including Arabidopsis thaliana (At5g54270). This sequence is highly conserved even in Ginko biloba and one of the major LHCII-forms of Physcomitrella patens

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.
