Peroxiredoxins (EC=1.11.1.15) belong to the enzyme family which is ubiquitous in all kingdoms of life. Prx Q enzyme acting by reducing hydroperoxides. Peroxiredoxins have no heme group, unlike the other peroxidases, but perform their enzymatic activity using cysteine residues with redox-active thiol groups. The ability of peroxiredoxins to hydrolyze hydroperoxides suggests that this protein family has a general function in oxidant defence.

In some species minor cross reactions with some larger proteins are seen. These may contain related iron-sulfur binding motifs. Therefore size verification of the reacting band is required. Due to the small size of the protein, care should be taken to differentiate between chemiluminescent signal from PsaC and non-specific signals from chlotophylls or lipids if pigment is retained near the bottom of the blot.For the most optimal results use:thylakoid membranes or PSI particles, solubilized in a SDS sample buffer (final concentrations: 63 mM Tris HCl, 10% glycerol, 2% SDS, 0.0025% bromophenol blue) with 2.5% beta-mercaptoethanol at 85C for 2 minutes. The samples were spun softly, then the supernatant loaded. This product can be sold containing ProClin if requested.

Format:

Storage Temp:

Protein standard buffer composition: Protein standard buffer composition: Glycerol 10%, Tris Base 141 mM, Tris HCl 106 mM, LDS 2%, EDTA 0.51 mM, SERVA Blue G250 0.22 mM, Phenol Red 0.175 mM, pH 8.5, 0.1mg/ml PefaBloc protease inhibitor (Roche), 50mM DTT.
Application Details:
Positive control: a 2 μL load per well is optimal for most chemiluminescent detection systems. Standard curve: 3 loads are recommended (eg. 0.5, 2 and 4μL). For most applications a sample load of 0.2 μg of chlorophyll will give a PsaC signal in this range. Exact loads can vary with the sensitivity of your system and the abundance of the target protein in your samples. Note: Optimal quantitation is achieved using moderate sample loads/well, generally 1 to 5 ug total protein. A trial experiment may be required i) to bring your sample load within the standard curve range and ii) to obtain a signal that is strong enough to reliably quantify but not so strong as to consume ECL reagents too quickly or saturate your detection system. These goals may achieved by adjusting both sample and standard loads.
Reconstitution:
For reconstitution add 95 l of sterile water. Note that due to glycerol in buffer, the lyophilized product appears as a dense liquid rather than a powder. Allow the product several minutes to solubilize after adding water. Mix thoroughly but gently. Avoid vigorous vortexing, as buffer contains detergent. Upon reconstitution, this standard is ready-to-load and does not require any additions or heating. See additional Handling Instructions below. PsaC standard protein concentration: 0.10 pmol/ l.
Molecular Weight:
11,5 kDa (larger than native protein due to the addition of His-tag), In most gels PsaC migrates between 9 and 14 kDa

Special application note:
Handling Instructions*IMPORTANT: In our experience, viscous liquids are surprisingly stable; insufficient mixing is the most common reason for unsatisfactory results. Following mixing, briefly pulse in a microcentrifuge to collect material from cap.Standard needs to be fully thawed and thoroughly mixed before each use. Proteins tend to stratify with the more dense layer after freezing. We recommend bringing the product to room temperature and either mixing by inverting or flicking tube 5-10 times. Pipetting up and down may also provide sufficient mixing, provided the tip is moved within the tube while taking up and expelling the liquid.
PsaD (PSI-D) is a core subunit of photosystem I highly conserved in all photosynthetic organisms (including bacteria with Fe-S type reaction centers). In eukaryots its encoded by 1 to 2 nuclear gene(s) and imported as a precursor into the chloroplast. In the thylakoid membrane it associates with PsaA and PsaB on the stromal site of the PSI core forming the Fd-docking site. PsaD is also required for the stable assembly of PsaC.

PsaG (PSI-G subunit of photosystem I) is a 11-kDa membrane protein that plays an important role in electron transport between plastocyanin and PSI and is involved in the stability of the PSI complex. PSI-G subunit is bound to PSI-B and is in contact with Lhca1. The protein inserts into thylakoids by a direct or "spontaneous" pathway that does not involve the activities of any known chloroplast protein-targeting machinery. PSI-G appears to be directly or indirectly involved in the interaction between Photosystem I and plastocyanin.

PsaH (PSI-H) is a conserved subunit of type I photosynthetic reaction centers (Photosystem I, PSI). PSI is an integral membrane multi-protein complex that catalyzes the electron transfer from plastocyanin (or cytochrome c6) to ferredoxin (or flavodoxin). Psa-H has been suggested to be involved in regulation of state1-state2 transitions. In plants and green algae Psa-H is nuclear encoded and imported post-translationally into the chloroplast where it inserts into the thylakoid membrane.

PsaL (PSI-L) is a conserved subunit of type I photosynthetic reaction centers (Photosystem I, PSI). PSI is an integral membrane multi-protein complex that catalyzes the electron transfer from plastocyanin (or cytochrome c6) to ferredoxin (or flavodoxin). Psa-L is binding pigments and has been shown to be involved in trimerization of PSI in cyanobacteria (but not in plants) and bind pigments in plants and cyanobacteria.In plants and algae Psa-L is nuclear encoded and imported post-translationally into the chloroplast where it inserts into the thylakoid membrane.

Photosystem I (PSI) of chloroplasts is a multisubunit membrane-protein complex that catalyzes the electron transfer from the reduced plastocyanin (or cytochrome c6) in the thylakoid lumen to the oxidized ferredoxin (or flavodoxin) in the chloroplast stroma. PsaN is necessary for docking plastocyanin to the PSI complex. PSI-N is the only subunit located entirely on the lumenal side of PSI.
