Anti-Lhca2 | PSI type II chloropyll a/b-binding protein

The light-harvesting protein Lhca2 is one of the four main and highly conserved types of chlorophyll a/b-binding proteins (Lhca1-4) of the light harvesting antenna (LHCI) of plant photosystem I. Lhca2 is imported as a precursor from the cytosol into the chloroplast. Upon integration in the thylakoid membrane Lhca2 forms a heterodimer (LHCI-680) with Lhca3 that associates with the PSI core close to PsaF and PsaK.A biochemical characterization of the plant LHCI antenna can be found in Klimmek et al. (2005) The structure of the higher plant light harvesting complex I: in vivo characterization and structural interdependence of the Lhca proteins. Biochemistry 44: 3065–3073.

BSA-conjugated synthetic peptide derived from the Lhca2 protein of Arabidopsis thaliana UniProt: Q9SYW8, Q8LCQ4, TAIR: At3g61470. This sequence is highly conserved in Lhca2 proteins of angiosperms (monocots and dicots) and gymnosperms as well as in At1g19150. This gene codes for the very low expressed Lhca6 protein which also has been denoted as Lhca2*1.

Antibody format is a total IgG fraction, which means that it is a pool of polyclonal antibodies obtained by purification of serum on Protein G, not on a specific antigen column.

Store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please remember to spin the tubes briefly prior to opening them to avoid any losses that might occur from material adhering to the cap or sides of the tube.
