Frequently Asked Questions

Question 1:
How to store the antibody?

Answer:
Store the undiluted solution at 4 °C in the dark. Freezing antibodies can result in a loss of activity caused by the freezing/thawing process. Diluting antibodies to working concentrations and storing at 4°C for more than a day should be avoided. Additionally, make sure to keep the antibody sterile. Under these storage conditions, your antibodies should remain active for up to one year and oftentimes longer.
