{{/_source.additionalInfo}}Anti-Lhcb4 | CP29 chlorophyll a/b binding protein of plant PSII
(Cat#: AS04 045)
Description
- Immunogen: 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 and Lhcb4.3 At2G40100).
- Host: Rabbit
- Clonality: Polyclonal
- Purity: Total IgG. Protein G purified in PBS pH 7.4.
- Format: Lyophilized
- Quantity: 0.5 mg
- Reconstitution: For reconstitution add 250 µl of sterile water
- Storage: 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.
- Tested applications: Western blot (WB)
- Recommended dilutions: 1 : 7 000 (WB)
- Expected | apparent MW: 31.9 | 29 kDa for Arabidopsis thaliana
- Confirmed reactivity: Arabidopsis thaliana, Camelina sinensis, Cucumis sativus L. cv. Jihong no. 2, Drosera capensis, Hordeum vulgare, Lactuca sativa, Nicotiana tabacum, Oryza sativa, Pisum sativum, Phaseolus vulgaris, Triticum aestivum, Triticale, Zea mays
- Not reactive in: Chlamydomonas reinhardtii (please use AS06 117 for this organism)
- 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.
