PetC | Rieske iron-sulfur protein of Cyt b6/f complex, protein standard

Standard curve: 3 loads are recommended (0.5, 2 and 4μl).
For most applications a sample load of 0.2μg of chlorophyll will give a PsbA signal in this range.

Positive control:a 2μl load per well is optimal for most chemiluminescent detection systems.

This standard is stabilized and ready and does not require heating before loading on the gel.
Please note that this product contains 10% glycerol and might appear as liquid but is provided lyophilized. Allow the product several minutes to solubilize after adding water. Mix thoroughly but gently Take extra care to mix thoroughly before each use, as the proteins tend to settle with the more dense layer after freezing.

The PetC protein standard can be used in combination with global anti-PetC antibodies to quantitate PetC from a wide range of species. Global antibodies are raised against highly conserved amino acid sequences in the PetC protein.

Quantitative western blot:  detailed method description, video tutorial

Concentration: after adding 225  µl of milliQ water final concentration of the standard is 0.15 pmol/µl

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.

This standard is ready-to-load and does not require any additions or heating. It needs to be fully thawed and thoroughly mixed prior to using. Avoid vigorous vortexing, as buffers contain detergent. Following mixing, briefly pulse in a microcentrifuge to collect material from cap.

Rieske Iron-Sulfur Protein (Q9ZR03)is located in chloroplast thylakoid membrane as a component of cytochrome b6-f complex, which mediates electron transfer between photosystem II (PSII) and photosystem I (PSI), cyclic electron flow around PSI, and state transitions. Alternative names: Rieske iron-sulfur protein, RISP, ISP, plastohydroquinone:plastocyanin oxidoreductase iron-sulfur protein, proton gradient regulation protein 1
