{{/_source.additionalInfo}}Anti-STN8 | Serine/threonine-protein kinase STN8 (chloroplastic)
(Cat#: AS10 1601)
Description
- Immunogen: KLH-conugated synthetic peptide (amino acids 425-438) specific for Arabidopsis thaliana STN8 serine/threonine proteinkinase, UniProt: Q9LZV4 TAIR:At5g01920
- Host: Rabbit
- Clonality: Polyclonal
- Purity: Immunogen affinity purified serum in PBS pH 7.4.
- Format: Lyophilized
- Quantity: 50 µg
- Reconstitution: For reconstitution add 50 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 : 2000 (WB)
- Expected | apparent MW: 54.9 kDa or 46 kDa on 6 M urea gel
- Confirmed reactivity: Arabidopsis thaliana, Triticum aestivum
- Not reactive in: No confirmed exceptions from predicted reactivity are currently known
- Serine/threonine protein kinase (EC=2.7.11.1), known as STN8 in Arabidopsis, and its Stl1 homologue in Chlamydomonas, are STN7/Stt7-like proteins that are not required for state transitions. The Arabidopsis mutants deficient in stn8 gene demonstrated highly reduced levels of the phosphorylated proteins of the photosystem II (Bonardi et al., 2005 Varionen et al., 2005). Alternative name: Protein STATE TRANSITION 8.

- For best results with this antibody sample buffer needs to contain 6 M urea (138mM TrisHCl pH 6.8, 6M urea, 22.2% Glycerol, 4.3% SDS).STN8 is a nuclear encoded protein which is localized in chloroplast, hence posses a chloroplastic target peptides (cTP) at the beginning of the amino acid sequence which is cut off. Accroding to TargetP (program that predicts the length of the cTP:s) the length of cTP for Stn8 is 49 amino acids. STN8 portein mobility can be also affected by urea present in the gel.Due to a high background signal with LHCII it is adviced to cut off a membrane below 30 kDa marker.
