产品说明
product information Background PsaA is a core protein of photosystem I. In plants and cyanobacteria, the primary step in oxygenic photosynthesis, the light induced charge separation, is driven bytwo large membrane intrinsic protein complexes, the photosystems I and II.  Synonym: Photosystem I P700 chlorophyll a apoprotein A1.       Immunogen N-terminal part of recombinant PsaA protein from Chlamydomonas reinhardtii P12154 Host Rabbit Clonality Polyclonal Clone Purity Serum Format Lyophilized Quantity 2 x 50 µl Reconstitution For reconstitution add 50 µl of sterile water to each tube 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 western blot (WB), immunogold (IG) Related products collection of antibodies to PSI proteinsrecommended secondary antibodyPlant and algal protein extraction buffer Secondary antibodies Additional information PsaA is a hydrophobic protein and we recommend to use PVDF membrane for transfer to assure best results application information Recommended dilution 1: 1000 with standard ECL (WB), 1: 20 (IG) Expected | apparent MW 82 | 55-60 kDa Confirmed reactivity Arabidopsis thaliana, Bryopsis corticulans, Colobanthus quitensis Kunt Bartl, Fucus vesiculosus, Haematococcus pluvialis, Hordeum vulgare, Nicotiana tabacum, Oryza sativa, isum sativum, Marchantia polymorpha (liverwort), Phaseolus vulgaris, Physcomitrella patens, Pinus strobus, Spinacia oleracea, Chlamydomonas reinhardtii, Synechococcus PCC 7942, Synechocystis PCC 6803, Scenedesmus obliquus, microalgae: Nannochloropsis gaditana Predicted reactivity dicots including: Lycopersicum esculentum, Panax ginseng, monocots including: Triticum aestivum  trees: Picea spinulosa, Pinus thunbergii, Populus alba, Citrus x limon, Bigelowiella natans, algae, cyanobacteria Not reactive in Chromera velia Additional information immunogold localization has been done in leaf material of  Arabidopsis thaliana Selected references Correa-Galvis et al.

Blots were blocked immediately following transfer in 2% ECL Advance blocking reagent (GE Healthcare) in 20 mM Tris, 137 mM sodium chloride pH 7.6 with 0.1% (v/v) Tween-20 (TBS-T) for 1h at room temperature with agitation. Blots were incubated in the primary antibody at a dilution of 1: 10 000 for 1h at room temperature with agitation. The antibody solution was decanted and the blot was rinsed briefly twice, then washed once for 15 min and 3 times for 5 min in TBS-T at room temperature with agitation. Blots were incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated, frecommended secondary antibody AS09 602) diluted to 1:50 000 in 2% ECL Advance blocking solution for 1h at room temperature with agitation. The blots were washed as above and developed for 5 min with ECL Advance detection reagent according the manufacturers instructions. Images of the blots were obtained using a CCD imager (FluorSMax, Bio-Rad) and Quantity One software (Bio-Rad). Exposure time was 10 seconds.

Agrisera针对植物蛋白质的保守氨基酸序列,Agirsera还**开发了数十种通用抗体(global antibodies),这类抗体几乎可以与所有的高等植物及藻类产生免疫反应,可为研究人员提供极为方便的选择。其中包括常用的植物Rubisco抗体,Rubisco即核酮糖二磷酸羧化酶,是植物组织中广泛存在的一种高丰度蛋白,在一些植物学WB检测时,经常被用作内参抗体使用。
