Product Information

Immunogen

BSA-conjugated synthetic peptide derived from Arabidosis thaliana Lhcb5 protein UniProt: Q9XF89, TAIR: AT4G10340 sequence. This sequence is highly conserved in Lhcb5 proteins from monocots, dicots and conifers but only partial conserved in Physcomitrella patens and Chlamydomonas reinhardtii.

Host Rabbit

Clonality Polyclonal

Purity Serum

Format Lyophilized

Quantity 200 µl

Reconstitution For reconstitution add 200 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 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.

Tested applications Immunohistochemistry (IHC), Western blot (WB)

Recommended dilution 1 : 1000 (WB)

Expected | apparent MW

30 | 25-26 kDa for Arabidopsis thaliana

Reactivity

Confirmed reactivity Arabidopsis thaliana, Hordeum vulgare, Drosera capensis, Oryza sativa, Pisum sativum, Spinacia oleracea, Triticum aestivum, triticale, Zea mays

Predicted reactivity

Not reactive in No confirmed exceptions from predicted reactivity are currently known.

Application examples

Application example

5 µg protein of (1) chloroplasts, (2) thylakoids, and (3) Photosystem I of Arabidopsis thaliana together with (4) BBY (Photosystem II) -particles from Pisum sativum were separated on 4-12% NuPage (Invitrogen) LDS-PAGE and blotted 1h to nitrocellulose. Filters were blocked 1h with 2% low-fat milk powder in TBS-T (0.1% TWEEN 20) and probed with anti-Lhcb5 (AS01 009, 1:1000, 1h) and secondary anti-rabbit (1:20 000, 1 h) antibody (HRP conjugated) in TBS-T containing 2% low fat milk powder. Antibody incubations were followed by washings in TBS-T (15, +5, +5, +5 min). All steps were performed at RT with agitation. Signal was detected with chemiluminescence detection reagent, using a Fuji LAS-3000 CCD (90s, standard sensitivity).

Background

Lhcb5 is one of the 3 minor highly conserved chlorophyll a/b-binding proteins associated with Photosystem II in plants and algae. As a part of the inner light-harvesting antenna it has been sugested to regulate (together with Lhcb4 and Lhcb6) the energy flow from the outer LHCII antenna to the PSII reaction center.
