Storage & Handling

Unopened vial can be stored at -20°C or -70°C for six months. For maximum results, quick spin vial prior to opening. Avoid repeated freeze/thaw cycles.

Activity

Mouse ACP5 has the ability to cleave the substrate, p-Nitrophenyl phosphate (pNPP). The specific activity is >22,000 pmol/min/µg.

Application

Bioassay

Application Notes

ALP5 Assay Procedure

1. In assay buffer, prepare dilution of mouse ACP5 at 0.1 µg/mL
2. Add 50 µL of mACP5 and 50 µL of prepared 2 mM substrate to plate. Include a blank for the substrate containing 50 µL assay buffer and 50 µL of 2 mM substrate.
3. At room temperature, incubate plate for 10 minutes in the dark.
4. To develop the color and stop the reaction, add 100 µL of 0.2 M NaOH.
5. Read (top read) absorbance in endpoint mode at 410 nm.
6. Calculate the specific activity:

Specific Activity (pmol/min/µg) = Adjusted Abs* (OD) x Conversion Factor** (pmol/OD)
Incubation time (min) x amount of enzyme (µg)

*Adjusted for the substrate blank
**Derived using calibration standard p-Nitrophenol (Sigma-Aldrich, Catalog # 241326).

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)
