PR-1 | Positive control/quantitation standard

Pathogenesis-related protein 1 (PR-1) is partially responsible for acquired pathogen resistance. Induced by INA, salicylic acid and pathogen infection.This product is a recombinant PR-1 protein, trunctated by first 26 amino acids, source: Arabidopsis thaliana, UniProt: P33154, TAIR: At2g14610

Standard curve: 3 loads are recommended eg. 0.5, 2 and 4 μl.For most applications a sample load of 10-20 μg of protein will provide with a 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.

For reconstitution add 90 µl of sterile water, Please notice that this product contains 10% glycerol and might appear as liquid but is provided lyophilized

Concentration:after adding 90 µl of sterile milliQ water final concentration of the standard is 0.10 pmoles/µLProtein 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.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 PR-1 protein standard can be used in combination with anti-PR-1 antibodies to quantitate PR-1 protein. Quantitative western blot: detailed method description, video tutorialThis product can be sold containing ProClin if requested

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.
