Antibody Products FAQ

1. How should I store Sino Biological Inc.'s Antibodies?

Specific storage recommendations are listed on the Certificate of Analysis. We recommend that all antibodies be aliquoted into smaller aliquotes and stored at -20° C or below. Avoid multiple freeze-thaw cycles as this will affect antibody activity. We cannot guarantee how the performance of the antibodies if they are not stored as stated on the datasheet.

2. What is the shelf life of Sino Biological Inc.'s antibodies?

Unless otherwise indicated in the data sheet, most of our antibodies can be stored at 2℃-8℃ for one month without detectable loss of activity and are stable for twelve months from date of receipt when stored at -20℃ to-70℃. Repeated freezing and thawing should be avoided.

3. How are Sino Biological Inc.'s Antibodies supplied?

All Sino Biological Inc's antibodies are supplied as liquid. It remains stable during the delivery process at ambient temperature. We have tested every antibody's stability and activity following a period of more than 7 days at -20°C, room temperature, or 37°C. Antibodies under all three conditions turned out to be equally active and stable.

4. My Sino Biological Inc's antibody was shipped without ice but the recommended storage conditions are listed as +4°C or -20°C, the activity have been affected?

No. Sino Biological Inc. ships thousands of antibodies every week to customers all over the world at ambient temperature. Loss of activity has never occured.

We have tested every antibody's stability and activity following a period of more than 7 days at -20°C, room temperature, or 37°C. Antibodies under all three conditions turned out to be equally active and stable.

However, upon receipt, antibodies should be stored according to the datasheet recommendations immediately.

5. Can you provide me with the immunogen sequence for the antibody?

The catalog number of the recombinant protein used as the immunogen is listed on the Certificate of Analysis. Please contact us via order@sinobiological.com if additional information is needed.

6. The antibody I'm interested in isn't validated for the species I want. Will it work?

Sino Biological Inc cannot guarantee the performance of an antibody in an un-tested species. We can, however, make some educated guesses based the sequence that was used to generate the antibody. However, we cannot guarantee cross-reactivity even if the aligned sequences have a high identity score.

We would greatly appreciate it if you would test our antibody on an un-validated species and share the results with us. We will issue you credits in return for your data.

7. Will Sino Biological Inc's antibody work in an application that is not listed in the applications table?

Customers can find all the tested applications for each particular antibody by visiting Sino Biological Inc Antibody website. We do not list any un-tested applications. We would greatly appreciate it if you would test our antibody on an un-validated species and share the results with us. We will issue you credits in return for your data.

8. Which dilutions of the antibody should I use in my experiment?

We list a dilution suggestion on the datasheet for most of our antibodies. Please remember that these dilutions and concentration estimates are simply recommended as a starting point, and it may require optimization based on your own experimental results.
