Stability Testing for Recombinant Human INPP5F. One aliquot (Control) was stored at 4°C for 7 days, while another aliquot (4XF/T) was subjected to multiple freeze-thaw cycles by freezing at -80°C and thawing four times over a 7-day period. Each freeze-thaw cycle involved placing the sample on ice and slowly thawing it until no ice crystals remained in the tube. A minimum of 24 hours elapsed between each freeze and thaw event. Following treatment, the reduced samples (4 µg/lane) were separated by SDS-PAGE and stained with Coomassie brilliant blue dye. Lane M: Protein ladder (Cat. No. 773302).

Inositol polyphosphate 5-phosphatase F (INPP5F), also known as phosphatidylinos phosphatidylinositide phosphatase itide phosphatase SAC2, is a member of INPP5 family. A key role of INPP5F is regulation of polyphosphoinositide metabolism and phosphoinositide signaling pathways by regulating the levels of inositol phospholipids. Positioned in the cytoplasm, INPP5F is closely associated with cellular membranes and participates in various cellular processes, including membrane trafficking, cytoskeleton dynamics, and signal transduction.
Mechanistically, INPP5F activates the Notch signaling pathway and upregulates c-MYC and cyclin E1 in hepatocellular carcinoma by interacting with ASPH. INPP5F also modulates the Akt/GSK-3β pathway by reducing Akt and GSK-3β phosphorylation levels. INPP5F is expressed in various tissues including heart, kidney, skeletal muscle, and brain. INPP5F contributes to tumorigenesis and tumor progression. INPP5F rs117896735 variant has been associated with an increased risk of Parkinson’s Disease.

- Why choose BioLegend recombinant proteins?
-
• Each lot of product is quality-tested for bioactivity as indicated on the data sheet.
• Greater than 95% Purity or higher, tested on every lot of product.
• 100% Satisfaction Guarantee for quality performance, stability, and consistency.
• Ready-to-use liquid format saves time and reduces challenges associated with reconstitution.
• Bulk and customization available. Contact us.
• Learn more about our Recombinant Proteins. - 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) = 10^6/ ED50 (ng/mL)
