CP43' | IsiA homolog of plant CP43 positive control/quantitation standard

The IsiA protein standard can be used in combination with anti-IsiA antibodies to quantitate IsiA from a range of cyanobacteria. Global antibodies are raised against highly conserved amino acid sequences in theIsiA 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 pmoles/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.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.

This product is the standard product of recombinant protein, source: Polycytial strain pcc6803.
