Western blot of N-terminal GST tagged recombinant human DJ-1 (PARK7). Lane 1: Molecular weight marker; Lane 2: 20 ng of recombinant human DJ-1 (PARK7) protein. The blot was incubated with 10 µg/mL of purified anti-GST epitope tag antibody (clone 4C10) (Cat No. 901601) overnight at 4°C, followed by incubation with HRP-labeled goat anti-mouse IgG (Cat. No. 405306). Enhanced chemiluminescence (Cat. No. 426302) was used as the detection system.

    Direct ELISA of purified anti-DJ-1 (PARK7) antibody (clone A16125E; Cat. No. 851502) binding to plate-immobilized N-terminal GST tagged recombinant human DJ-1 (PARK7) protein. ELISA was performed by coating wells with 100 ng of DJ-1 protein. The wells were then incubated with the primary antibody at 37°C for 45 minutes, followed by incubation with horseradish peroxidase labeled goat anti-mouse IgG secondary antibody. TMB (3, 3', 5, 5' tetramethylbenzidine, Cat. No. 421501) was used as the detection system.

Description

DJ-1 (PARK7) belongs to the peptidase C56 family of proteins and is expressed in almost all human cells and tissues. DJ-1 is a multi-functional protein associated with mitochondrial function, mitophagy, and male fertility. It acts as an oxidative stress sensor, redox-sensitive chaperone and protease. Therefore, the protein has an important role in cell protection against oxidative stress and cell death. DJ-1 is also associated with prostate cancer, and specific mutations of the protein are linked to autosomal recessive, early onset Parkinson’s disease.

How does the activity of your recombinant proteins compare to competitors?

We quality control each and every lot of recombinant protein. Not only do we check its bioactivity, but we also compare it against other commercially available recombinant proteins. We make sure each recombinant protein’s activity is at least as good as or better than the competition’s. In order to provide you with the best possible product, we ensure that our testing process is rigorous and thorough. If you’re curious and eager to make the switch to BioLegend recombinants, contact your sales representative today!

What is the specific activity or ED50 of my recombinant protein?

The specific activity range of the protein is indicated on the product datasheets. Because the exact activity values on a per unit basis can largely fluctuate depending on a number of factors, including the nature of the assay, cell density, age of cells/passage number, culture media used, and end user technique, the specific activity is best defined as a range and we guarantee the specific activity of all our lots will be within the range indicated on the datasheet. Please note this only applies to recombinants labeled for use in bioassays. ELISA standard recombinant proteins are not recommended for bioassay usage as they are not tested for these applications.

Have your recombinants been tested for stability?

Our testing shows that the recombinant proteins are able to withstand room temperature for a week without losing activity. In addition the recombinant proteins were also found to withstand four cycles of freeze and thaw without losing activity.

Does specific activity of a recombinant protein vary between lots?

Specific activity will vary for each lot and for the type of experiment that is done to validate it, but all passed lots will have activity within the established ED50 range for the product and we guarantee that our products will have lot-to-lot consistency. Please conduct an experiment-specific validation to find the optimal ED50 for your system.

How do you convert activity as an ED50 in ng/ml to a specific activity in Units/mg?
Use formula Specific activity (Units/mg) = 10e6/ ED50 (ng/mL)
