Pierce™ Antibody Biotinylation Kit for IP - FAQs

I'd like to use the Pierce Antibody Biotinylation Kit for IP (Cat. No. 90407). Is it okay if my antibody storage buffer contains sodium azide?

Make sure that the final concentration of sodium azide in the reaction volume does not exceed 0.02%. The Zeba Spin Desalting Columns provided in the Pierce Antibody Biotinylation Kit for IP can be used to remove sodium azide from the storage solution.
